The World’s Most Energy Efficient Lighting Technology Engineered for a Clean Tomorrow

IntroductionWhile the rise of technology has allowed U.S.

businesses to market their products and servicesacross the globe, the expansion of global

commerce has allowed developing countriesto quickly enter and penetrate the global

market place. U.S. businesses are realizing that they are now competingwith governments and businessesaround the world that often havelower labor rates, cheaper rawmaterials and lower energy costs.To remain competitive in the market place, U.S. companies arefeeling the pressure to lower theiroverall operating costs.

With rising energy costs and avolatile energy future, businessesare finding that they can bettermeet their financial goals by controlling their total operatingcosts through energy conservation

measures which can immediatelyand substantially impact their bottom

line performance. In most businesses,energy required to operate lighting

equipment is a primary constituent oftheir overall energy bill, therefore some

type of new, energy-efficient, lightingequipment is often a solid investment to

improve your company’s bottom line. Renovatingthe lighting system in your industrial or retail

space can result in substantial energy savings - evenusing conservative numbers, paybacks can be realized

in as little as ½ to 3 years. To provide additional incentivesfor energy conservation, federal programs such as EPAct, as

well as utility rebates, further enhance the financial package thatmost CEO’s and CFO’s review prior to final approval of a project.


manufacturing is looking to improve its bottom line by cutting operating costs through an energy savings program. It determines thatone of the quickest ways to realize a payback on their investment would beto undertake a lighting renovation project. After a quick visit with an

energy savings guru, a new lighting system was installed for $38,000 cutting their lighting billin half to approximately $20,000/year yielding a payback in less than 2 years – a seeminglysound investment...

...A few months after installation, the plant manager noticed a small decrease in productivity. After a thorough review ofthe facility, the plant manager soon realized that some areas of the facility were notas bright as they used to be and other areas were far worse than previously illuminated.An overall productivity loss of 1% was incurred when the company chose to install theirnew ‘energy-saving’ lighting system.

While seemingly small at only 7.2 minutes per day (less than 1 minute per hour),the plant manager conducted a quick impact analysis and ascertained the following:

ABC manufacturing employs 100 employees who each work 40 hours/week to make 8,000widgets per month. If each widget sells for an average of $500 then that company willmake $48,000,000 in revenue annually. The 1% loss in productivity equates to a revenueloss of $480,000/year. In short, every dollar of energy saved from their new ‘energy-saving’ lighting system winds up costing the company $13 in lost revenue.

After bringing this to the attention of senior staff, the company then decided tobring in a lighting expert from Holophane.

The local Holophane sales representative, who had been extensively trained in all facetsof lighting design, quickly determined that the initial design did not take into accountthe effect that heat and airborne grease from their daily manufacturing operationswould have on their overall light output.

A ‘Quality’ lighting solution that realized the same 50% energy savings was installedand ABC manufacturing now realizes a 1.5% improvement in productivity over their oldlighting system. Instead of losing 480,000/yr in revenue, the company now realizes a$720,000/yr revenue gain + the $20,000 of energy savings every year!

Almost any lighting solution can save you energy, but a ‘Quality’ lighting solution can helpimprove your company’s bottom line through increased sales or productivity and energy savings.In industrial facilities, a new lighting system may create a more productive work environment.

Due to the high cost of operationscoming from salaries and benefits, a 1 percent increase in productivity cancompletely pay for even the mostexpensive lighting systems. In retail environments, an updated lighting system can be easily justifiedthrough the increased revenue fromadditional customers attracted to the‘newly refreshed store’. Delayingyour lighting renovation project canactually cost your company revenue.

UsingHolophane luminaires for yourlighting renovation project willyield the lowest total cost of ownership and the greatestreturn on your investment whileconserving our environment andconsuming less energy.



Lighting Renovation MethodsWhen considering updating a facility’s lighting system, there are basically three methods to consider, each with varying degrees of cost, complexity and potential energy savings:

Retrofitting: When this method is used, lighting componentsare examined for efficiency and then replaced with componentsthat improve the efficiency of the installation. Lamps and ballastsare usually replaced while reflectors, lenses or louvers may becleaned or replaced depending upon condition and budgetary andtime constraints. Sometimes simple changes in the control system,such as adding motion sensors, are a possibility.

Replacement: This method involves replacing existing luminaireshaving older technology with a completely new luminaire havingupdated energy efficient technology on a one-for-one basis.Luminaires using HID probe start lamps or fluorescent T12 lampsare replaced with luminaires using HID pulse start lamps orT8/T5HO fluorescent lamps and luminaires using magnetic ballastsmay be replaced with luminaires having electronic ballasts.Additionally, the appearance of the luminaire may change drasticallydue to new shapes, reflector materials and/or body styles.


Hybrids of the previously mentioned methodologies are analternative, but choosing between these three methods is criticalbecause the results are considerably different.

Relighting: This method requires a more in-depth analysisnot only of the lighting components but also of many otherissues affecting the performance of the lighting systems suchas circuit sizing, appearance, interior design, traffic control,visibility, psychological responses, regulatory compliance, userexpectations, flexibility requirements, day-lighting contributionand control systems. Old luminaires and wiring/conduit areremoved; new lighting systems are installed, typically withnew control systems and in different locations than the existing system to maximize energy savings.



A Retrofitting project can usually be performedwith minimal disruption. But other than a subtle“freshening” of the space, a lighting retrofit seldom changes the character of the space. Theresult is often seen as converting an ‘inefficientand dated lighting system’ to an ‘efficient anddated lighting system’. Retrofitting is relativelyeasy to calculate cost and payback, and it is easyto manage. Retrofitting also tends to cost lessthan Replacing or Relighting, but Retrofitting is typically not viewed as a capital improvementand therefore treated more like a mechanicalrepair. For buildings that have a modest missionor don’t have to compete in the marketplace, like government buildings, a retrofit may be analternative.

A one-for-one Replacement project can often be performed with minimal disruption to operations, but the space often looks substantially different due to the change in luminaire appearance and performance. A Replacement project normally costs more than a Retrofit project, but is often less complex and time consuming to perform.Replacement projects are typically considered a capitalimprovement and therefore often qualify for utilityrebates and other financial incentives. While the costof moving or adding circuits is usually eliminated, thefinal result is typically better than a Retrofit, but is oftennot the optimal solution in regards to performanceand energy savings.


While Retrofitting was popular in the 90’s whenenergy costs were relatively low, rebates and taxincentives coupled with today’s higher energycosts make one-for-one Replacement andRelighting projects the preferred methodologies.There’s a myriad of opportunities to cut moneyout of a project that is viewed as too costly. Usinglower grade luminaires, compromising on requiredlight levels, hiring unlicensed labor, using cheaper materials and overlooking long term gains are allways to recoup initial costs. However, there isnothing more costly to your business than a project that causes disruption to your operations.Holophane Solutions yield the lowest total cost ofownership and minimize this disruption over thelife of the system. More importantly, your company can realize incremental gains in revenuethrough increased productivity or new customersby relighting your facility!

A Relighting project often requires major work that canbe disruptive to business and building operations, butthe result is typically greater energy savings through amore efficient lighting system when compared toRetrofitting or Replacement methods. Additionally, thenew lighting system is often perceived as contemporaryand thus more appealing. Relighting requires more timeand initial costs and is usually considered a capitalimprovement. Although more costly, it may prove toprovide the lowest total cost of ownership in the longrun. Incentive programs like EPAct and/or rebates fromthe local utility are excellent ways to defray the higherinitial costs. Relighting is a thorough approach that considers factors that affect the quality of light as wellas initial and operating costs. Because Relighting is not a clear-cut process of simple engineering, considerationsand results may vary, but the final decision almost alwayshinges upon an economic analysis.



Environmental ConsiderationsThe lighting designer must take into account a variety of environmental factors including user needs and preferences, safety regulations, maintenance requirements and energy consumption. To help you navigate through the multiple lighting possibilities, these factors are discussed in greater detail below.

Matching existing light levels, when relighting a facility, is a common mistake. Most retail andindustrial facilities use lighting technology that depreciates over time, therefore the designed illumination level should be focused on what light level is required at some predetermined point in the future. If your goal is to merely equal current light levels with a new lighting system, you may be missing opportunities to capture incremental savings or improve productivity.

Analysis of the SpaceAn important aspect of lighting design is a detailed analysis ofthe environment. Functional elements that impact lightingdesign and affect the overall light delivered to the task includeceiling height, room surface finishes, work plane height, windows, skylights or other fenestrations, equipment size and shape, the geometry of the space, flexibility requirements,removal of hazardous wastes and existing wiring conditions.

Environmental conditions, including dust and dirt, presence of chemicals, airborne grease, moisture, insects, temperatureextremes, vibration and incidental abuse have a significanteffect on the selection of the proper luminaire. Food processingareas, for example, sometimes require special options for lightingfixtures, whereas retail lighting is often dependent upon thetype of product or service being sold, the size and location ofthe store, function performed within specific areas of the store,colors and textures of products, method of display (racks, gondolas or counters) and the overall merchandising strategy.

Exterior spaces also require evaluation. Proper lighting caninvite and direct potential customers to enter the store, enhancethe architectural features of a building at night and providesafety and security. General exterior considerations include thetype and color of exterior building materials, type and locationof plants used in the landscape, and the placement of exteriorlighting so it does not interfere with driveways or produce glare.The design considerations must also balance with the company’sbrand image.


Retail environments require luminaires that are not onlyenergy efficient but also aesthetically pleasing. Attractingand guiding customers through the store while aiding thecustomer in merchandise evaluation through proper colorrendering, glare control and vertical surface illuminationare primary concerns. Furthermore, lighting systems forretail applications must be flexible and easily controlledthrough various means such as dimming or dual circuits.

Outdoor environments require luminaires that meet certainaesthetic requirements while offering exceptional performance.Both optical performance to optimize pole spacings and maximize safety and security and luminaire performance toinsure low maintenance costs and down time.

Industrial environments often involve grease, oil, relativelyhigh temperatures, smoke, dust, or steam which candecrease a luminaire’s efficiency. Using the latest in optical,electronic, and thermal management technologies,Holophane’s luminaires are designed specifically for a variety of environments to create safe, and sanitary environments while providing effective and energy efficient solutions for our customers over the long haul.



In some instances, activities within the same space maychange throughout the day. Manufacturing activities may be conducted during one shift, maintenance of equipmentperformed during another shift, and security may be necessaryduring the non-productive periods. Each activity may requiredifferent illumination levels, thereforemanual or automatic controls such asbi-level switching, on/off switchingand/or dimming controls may be beneficial. In multi-location facilities, building automation systems are available to seamlessly integrate all aspects oflighting control including low-voltage switching, dimming,occupancy sensing and Daylight Harvesting™ systems to maximize corporate energy savings. Holophane offers scalable and flexible control systems from occupancy sensorsfor the simplest of applications to customized functionality indistributed controls for large complexes that may be spreadacross the globe.

Safety Requirements

Light levels must be sufficient to minimize on-the-job injurieswhich occur more frequently in industrial settings. Lightingmust also ensure a safe environment during an emergency. In the event of a fire or power outage, emergency lightingand exit signs must enable occupants to identify a clear pathof egress, even through smoke. Holophane offers Emergencyand Exit lighting even for hazardous locations.

Flexibility and Control Requirements

Changes in the work space often require general renovations.If the location of product displays, assembly lines or storageracks change, the lighting must be re-evaluated. In retail stores

and certain industrial applications, where task locationschange relatively frequently, the use of flexible wiringsystems may offer significant advantages. While initialluminaire installation time will be slightly reduced,time and cost savings when relocating luminaires in the

future becomes significant when utilizing our Holoflex®

modular wiring system.

Maintenance Requirements

Maintenance requirements can be an important consideration whenchoosing a lighting system. A lighting system that requires minimalmaintenance costs allows the maintenance team to concentrate theirefforts on tasks such as keeping machines and people productive;tasks that directly effect revenue generation. In many industrial orbig box retail applications, luminaires are mounted at high elevations,directly over machinery, tall racks or in locations where special equipment is required to access the luminaire.

While some fluorescent lamps may have longer life than traditionalHID lamps, most fluorescent high bay lighting systems will require 2 to 4 times as many lamps and ballasts per fixture as an HID lightingsystem to maintain equivalent light output. Furthermore, HID ballastsoften have a rated life that is 2 to 3 times the life of a fluorescent ballast. Selecting luminaires with multiple types of lamps and ballastsmay cause issues with the maintenance department who now has toinventory more components. However, in some cases this may bebest to achieve your overall lighting objectives and greatest energysavings. Holophane offers a variety of fluorescent and HID luminairesthat incorporate maintenance savings features into its products.

Energy Requirements

In light of sweeping energy conservation measures, the Energy PolicyAct (EPAct) requires all states to meet minimum energy requirementsas specified in the ASHRAE/IESNA Standard 90.1 code. Standard 90.1establishes watts-per-square-foot criteria for various types of applications.Lighting is one of the leading energy constituents and can have a substantial impact on overall operating costs. Design criteria shouldevaluate the local energy rate, all appropriate light loss factors, lightingusage requirements throughout the day, and the availability of energysaving technologies. In most cases, using Holophane luminaires willresult in a significant energy reduction through either fewer luminairesor lower wattage while maintaining the designed illumination level.See HL-2242, Holophane’s EPAct brochure for more information on theEnergy Policy Act of 2005.



Cost Considerations

The total cost of ownership of a lighting system can be broken downinto three categories:

1) Installation costs - luminaire, wiring/conduit, and labor

2) Maintenance - ballast replacement, lamp replacement, cleaning, and labor

3) Operating - energy consumption

Of these three categories, operating costs (energy consumption) consists of about 80% of the total cost over the life of a lighting system. Incremental costs in purchasing energy-saving components arepaid back quickly with the operating savings. Premium design andmaterials selection may increase initial capital costs, but offer significantadvantages such as increased light levels, superior color rendition andconsistency, better uniformity, less glare, less maintenance, and loweroperating costs.

It is also important to consider the financial benefits that result fromhigh quality lighting: improved productivity, new customer acquisition,lower rejection rates, customer retention, better quality control, andincreased customer satisfaction.

Regulatory Compliance

Along with energy requirements, other factors to be consideredare the requirements from the Americans with Disabilities Actwhich provides guidelines and specifications for barrier-free environments. Other regulatoryagencies include but are not limitedto NFPA, NEC, UL, OSHA, USDA,NSF, NEMA, ANSI/IESNA, and theIEC each with their own specificrules and regulations that vary by application type. Your localHolophane sales representative can help you determine which regulations are appropriate for your particular application.

sThermal Factor

Unlike HID lamps, fluorescent light sources are sensitive to temperature extremes. Optimum light output for most fluorescentlamps occurs when the air temperature surrounding the lamp is25°C (35°C for T5 and T5HO lamps). Any temperature above orbelow optimum reduces light output. In general, the higher theluminaire mounting height is, the hotter the operating temperaturewhich is especially true in unconditioned spaces. These two thermalfactors are often disregarded in lighting design calculations andcan prove to have a significant difference between designed lightlevels and actual light levels.

Temperature also has a tremendous effect on the life expectancy ofa ballast and its related components. Therefore, it is important notto exceed the maximum ambient rating of the fixture. Operating a fixture in environments that are cooler than its rated ambienttemperature will greatly increase ballast life. It is generally acceptedthat for every 10° C below the fixture’s rated ambient temperaturethe fixture is operated, the life of the ballast and capacitor doubles.

Holophane manufactures several luminaires incorporating thermalmanagement of the lamp and/or the ballast into their design.Your local Holophane sales representative can help you determinethe proper thermal factor and the appropriate luminaire for yourapplication in your design analysis.



When choosing a new lighting system, it is critical that certain considerations are made. Failure to make these considerations may determine whether your lighting renovation is a long term success or not. How much maintained light is needed, why do Ineed to account for light loss factors, what is uniformity andmany other careful considerations such as these will insure asuccessful project.

Illumination Considerations

Illuminance Levels

Illuminance is defined as the amount of light (called lumens)reaching a surface and is measured in “footcandles” orlumens per square foot. The metric equivalent is measuredin “lux” or lumens per square meter. The appropriate illuminance for a space depends upon how the space isbeing used in addition to the age of the workers (older eyesrequire more light), the speed and accuracy requirements ofthe task, the task contrast, and whether errors affect healthand safety.

Recommended lighting levels are usually derived from theIESNA Lighting Handbook, however some regulatory agencies,worker’s unions or OSHA may require more stringent illumination levels. For example the USDA strictly regulatesthe lighting requirements within the Food Processing industry.Many factors have an impact on proper light levels, includingage, speed, accuracy, contrast, glare, flicker, distribution andothers. The influence of these factors may raise or lower thedesired light levels. For detailed information regarding theseand other related issues, consult your local Holophane factorysales representative. Holophane’s sales consultants are lightingexperts - they go through extensive and continual training sothey can inform our customers of the latest technologies and the best solution for their lighting requirements.


Light Loss Factors

When performing lighting calculations, many factors can cause theactual illuminance to vary from the calculated illuminance, It is important to determine what your “maintained” light levels should beinitially and plan accordingly to reach that goal. For example, incorrectsurface reflectance’s, not accounting for large machinery or otherobstacles that block or reflect light and/or incomplete or inaccuratelight loss factors (LLF) can all affect your maintained or actual light levels. Light Loss Factors are used to adjust lighting calculations from a controlled laboratory environment to actual field conditions and/orfrom an initial installation condition to a maintained predeterminedtime frame condition. Total LLF takes into account that lighting fixtures will get dirty over time, that lumen output of certain lamptypes are temperature dependent, that lamps will age causing thelumen output to decrease over time and that ballast operation plays a factor in lumen output. At a minimum, the following Light LossFactors must be taken into account:

• Luminaire Dirt Depreciation (LDD) – simply put, theaccumulation of dirt on luminaires results in a loss of light output. The amount of dirt depreciation or light loss, is dependent upon the luminaire construction, luminairematerials and surrounding atmospheric conditions.

•• Holophane has always utilized glass reflectors instead ofacrylic or aluminum reflectors. Unlike acrylic or aluminum,glass is an inert material that resists taking on the electrostatic charges that attract dirt and dust particles.

•• With the heat generated by the lamp, a constant flow of hot air creates a “venturi effect” that minimizes dirtbuildup. This simple design conceptinsures that LDD is minimized regardlessof the atmosphere it is in.

•• Unlike other materials, glass can be cleaned and broughtback to 100% efficiency throughout the life of the opticallowing it to transcend time.

• Lamp Lumen Depreciation (LLD) – most lamps yieldcontinuously lower lumen output over their operating lives.LLD is calculated by dividing mean lumens by initial lumens.The amount of lumen depreciation is dependent upon thelamp type, lamp wattage, number of starts and burn hours.These lamp lumen depreciation values are readily availablefrom your lamp manufacturer and must be taken intoaccount when completing any lighting design.

• Thermal Factor (TF) – discussed on page 17 of thisbrochure.

• Ballast Factor (BF) – ballasts are used to convert linevoltage to lamp voltage and to regulate the current for lampstart up and for lamp running. Holophane designs andmanufactures it’s own HID ballasts for a ballast factor of 1.0.This means that each lamp is operated at full wattage. Aballast factor of anything less than 1.0 means that the lampwill not receive the intended wattage and will, therefore,not generate the lumens intended thus reducing light output. It is critical to know the ballast factor of the fixture being used in your design so that you can accuratelycalculate the number of fixtures needed to meet your footcandle requirements.

Don’t be tricked into believing that the light levels that you see in a new installation will be the light levels over the long haul.Holophane designs their luminaires to maximize lumen outputwhen all light loss factors are considered. This results in fewer fixtures and lower operating costs to receive the maintained lightlevels that the end user requires.



Contrast

To be readily visible, each detail of a visual task must differ in luminanceor color from its background. Visibility is at a maximum when contrastof an object with its background is very high. For example, darkblue lettering on a yellow background exhibits high contrast and isvery easy to read.

However, light blue lettering on a dark green background is considered low or poor contrast and is very difficult to decipher.Whenever possible, task contrast should be made as high as possible. Higher illuminance through supplemental lighting may help compensate for poor contrast.

HIGH CONTRASTDesirable

LOW CONTRASTUndesirable

Uniformity

For most industrial facilities, lighting uniformity is essential for goodvisibility, however certain tasks or areas may require greater lightlevels. Light pattern striations (non-uniform lighting) in the workspace can be distracting or confusing depending upon the taskbeing performed. Work surface illuminances that are 1-1/2 to 3times greater than the surrounding areas assist in directing occupant’s attention to the task, however greater luminance ratiosmust be avoided to minimize visual fatigue. It is potentially a wasteof energy to maintain uniformity between adjacent areas that havesignificantly different visibility and illumination requirements such asstorage racks next to an inspection area. In these instances, thedesigner will need to apply the appropriate illumination to eacharea, taking care not to exceed the recommended maximum luminance ratios. To accomplish this, use luminaires of differentwattages, change the quantity and spacing of luminaires in thoseareas or use task lighting.

For retail facilities uniformity may or may not be desired as previouslydescribed in the Lighting Techniques section. In general, as theproduct offering becomes more specialized (e.g. jewelry store)and/or the square footage becomes smaller, the less ambient lightingthe store will typically have and the more accent lighting the storewill incorporate.

Many factors contribute to uniform lighting, including direct illumination that shines downward from a luminaire and indirect or ‘bounce’ light that reflects off the ceiling and other surfaces.Holophane optical systems control the light so it reaches all areas within a space without spilling over into other areas whereillumination is not desired.

Improved uniformityand reduced fixtures


Spacing Criteria

In order to maintain good uniformity in a space, the manufacturer’s published spacing criterion (SC) for a givenfixture must be known. If you multiply the spacing criterionby the distance from the bottom of the fixture to the workplane, you arrive at the maximum recommended fixturespacing. Fixtures with low SC have more of a downwardthrow and need to be spaced closer together to maintainuniformity, and fixtures with higher SC have a more wide-spread distribution and can be spaced further apart. Spacingcriteria are based on providing uniform illumination and arenot a means of defining illuminance levels. This then becomesthe engineering tradeoff – light level vs uniformity. Twoluminaires having the same total lumen output, but differentspacing criterion may provide radically different light levelsEVEN if the spacing of the two systems is identical (which isoften the case in a 1-for-1 relighting application).

Distribution

Human beings often look straight ahead at a verticalplane rather than down toward a horizontal plane so theilluminance on a vertical plane is a critical element. Many

tasks such as shopping, machining, driving forklifts, readinggauges and stocking shelves are located in the vertical

plane. To light the vertical plane, pay close attention tofixture selection and fixture placement. In open areas,

fixtures with wide distributions may be required in additionto supplemental task lighting to appropriately light thevertical plane and overcome obstructions. In tall aisles,

such as those found in factory outlets or warehouses, luminaires with narrow distributions may be required in

order to provide appropriate vertical light levels at eye level.

Shadows

Large machinery and/or tall racks may obstruct light and causeshadows unless good lighting techniques are applied. Harsh shadows are not desirable and can be avoided by providing illumination from many different fixtures or from large diffusingluminaires. However, soft shadows that are less pronounced canaccent the depth and form of objects. Clearly defined shadowsoften aid in the visibility of engraved polished surfaces, some typesof bench work and certain textile inspections. Supplementarydirectional lighting combined with diffused general lighting from several fixtures can help achieve this effect.

Glare

There are two types of glare, direct glare and reflected glare. Direct glareoccurs when light travels directly from the lamp source to the eye. Reflected

glare, also known as veiling reflections, results when light reflects from a shinysurface, such as from a luminaire’s reflector, or other glossy surfaces within

the field of view. Glare can cause fatigue, headaches, annoyance, discomfortand productivity loss due to reduced visual performance and visibility.

Direct glare can be reduced using the following techniques or combinationsof techniques: 1) paint the ceilings white and choose luminaires with high

(15-25%) uplight component to reduce the harsh contrast of the high luminance source and the dark background 2) choose luminaires with deepreflectors that block the lamp from the field of view 3) choose fixtures with

louvers or lenses to conceal the lamp 4) decrease the luminance of the sourceby using lower wattage lamps and spacing fixtures closer together.

Reflected glare can be reduced using the following techniques or combination of techniques: 1) position the lighting fixture or the task so thatthe reflected image is directed away from the observer 2) select fixtures with

adequate shielding or diffusing media 3) use lower luminance lamps andspace fixtures closer together.

Color Rendering

The use of color in retail stores or industrial plants is notnew, yet in today’s world of colored lighting and coloredmaterials, having the ability to determine the exact colorof an object may be more important in some areas than inothers. Color is a wonderful tool used to attract customersto specific products, sort various grades of product,emphasize brand image or locate items faster within awarehouse.

Color rendering is the ability of a light source to representthe true colors of an object. The closer the color renderingindex (CRI) is to 100, the more natural the colors will appear.For example, a metal halide lamp, which casts a whitishlight, can have a CRI as high as 90. A high pressure sodiumlamp, which imparts a yellowish color, has a CRI as low as20. Therefore a metal halide source will be more appropriatefor color sensitive areas even though a high pressure sodiumlamp may be more efficient by providing greater lumensper watt.


It is hard to place a dollar value on lighting deficiencies such asdirect and reflected glare, shadows or uneven light distribution.However, experience shows that as the purchasing price for a lighting system decreases within limits, operating costs goup. This is reasonable since a commodity grade luminaireoften is not as robustly designed and constructed as a morehighly engineered system. In addition, commodity gradeluminaires are usually made of inferior quality materials. A lighting system’s design, materials, and construction will dictate its usefulness, efficiency and durability over time. The final price however, will be determined by the lightingsolution’s performance and its short-term and long-termoperating costs.

Holophane lighting solutions provide the best combination oflighting performance with low owning and operating costs.State-of-the-art optical systems promote energy efficiencyand wider spacing between luminaires. Quality materials anda highly engineered design assure the luminaires provide reliable performance with minimal maintenance for manyyears.

Holophane’s software, ‘SALE’, is a financial lighting program that compares the total costs of ownership for two or more different lightingsystems. The program evaluates the systems in terms of initial costs,maintenance costs and annual operating costs. The installed cost isonly the first part of the equation. Higher initial costs may be quicklyoffset by greater energy efficiency and lower maintenance costs overthe life of the luminaires, thereby yielding an overall lower total cost ofownership.

‘SALE’ compares systems in terms of payback time and net presentvalue. The user may make comparisons based on any combination ofinstallation, energy, and maintenance costs. Under installation costs,the user has the option to include or not include variables associatedwith conduit, wiring, outlet boxes and fixture installation. This meansthe user can compare systems based on energy and maintenance costsversus initial fixture costs alone providing a clearer picture of the totalcost of ownership.

Lighting EconomicsFirst cost or unit costs should not be the only consideration whenexamining the economics of a lighting system. A better gauge ishow efficiently the entire lighting system will operate over time.

Rising energy costs have incited many companies to take a second look at their electrical systems. Whenthe management at FAG Bearings Corporation decided to retrofit the aged lighting system at its Joplin,Missouri plant, the main objective was to reduce energy consumption.

FAG Bearings is a German-owned manufacturer providing ball and roller bearings of all sizes and types.Customers include many renowned machine, vehicle and device manufacturers all over the world. Thefacility is comprised of four buildings totaling 250,000 square feet.

During the early stages of the project, an energy retrofit company was consulted about replacing just theballasts in the facility’s existing low bay lighting system. The system used 400-watt high-pressure sodium(HPS) lamps.

However, because of the fixtures’ poor physical condition, the decision was made to retrofit the entirelighting system. Over the years, the plastic lenses on the luminaires had yellowed to the point that thelight output was substantially decreased and many of the relamp doors were broken or missing.

Holophane Enduralume® fixtures with enclosed optics were selected for the retrofit. The fixtures, whichuse 400-watt pulse start metal halide lamps, include a non-yellowing borosilicate glass refractor for lowbrightness and end of life lamp containment.

According to Charlie Kissell, electronic technician for FAG Bearings Corporation, the pulse start lampswere selected because of their longer life and higher initial and maintained light levels. The metal halidelamps also have excellent color rendering capabilities.

“Although energy reduction was our primary objective, we also constantly strive for methods to improvethe quality of our products,” said Kissell. “Because bearings are manufactured to very exact tolerances,the lighting is critical to producing an in spec product.”

A total of 180 Enduralume fixtures are installed in Building A, replacing 225 low bay fixtures. TheEnduralume luminaires were mounted at 22 feet on the open pan metal deck ceiling, and spaced 20’ x 20’ on center.

Based on FAG Bearing’s production schedule, the Enduralume units were installed above existing equipment during the off-shift hours. New mounting points were required since fewer luminaires wereused with greater spacing between the units. Illumination levels are 55 footcandles maintained.

The Enduralume fixtures are manually controlled and continuously illuminated. FAG Bearings installedEnduralume fixtures in the other three buildings.

We have received many positive comments from employees who feel thenew lighting system helps them see better. A number have indicated thatthe lighting helps them produce a higher quality product

Luminaires may utilize fluorescent or high intensity discharge sources that contain smallamounts of mercury. New disposal labeling for these lamps includes the mercury identifiershown on the right to indicate that the lamp contains mercury and should be disposed ofin accordance with local requirements.

Information sources regarding lamp recycling and disposal are included on thepackaging of most mercury-containing lamps and also can be located atwww.lamprecycle.org.

Lack of proper lighting can cause increased returns of goods, less productivityand lower corporate profit. In some cases improper lighting can invite thethreat of possible operation shutdown or diminished brand image. Holophaneluminaires are optically engineered to provide enhanced visibility through highvertical surface illumination required on processing equipment, displays, signage, racks, finished goods, machinery, distribution areas, railroad cars,trucks and containers to speed product identification, minimize fatigue, reducethe possibility of pilferage and increase employee morale and productivity.
