Site Considerations - Customer Criteria and Lighting Basics

Reasons for Outdoor Lighting1. Safety:

• Protecting people from things including safe working conditions, safe passage and identification of hazards or obstructions

2. Security: • Security lighting is intended to protect people and property from criminal

activities.

3. Wayfinding:• Illuminating ones location, destination and means to get there from your

current location.

4. Aesthetics• Designers raise the attractiveness of a design and assess what kind of

emotions the lighting should evoke.

Good LED Area Luminaire Typical MH Area Luminaire

• LED• Greater coverage• No wasteful hot spot• Better back-light control• 70% energy savings

Example of Replacing Metal Halide

• Metal Halide (hydroformed reflector)• Lots of light at nadir (hot spot)• Lots of light behind the pole

The Standard for Lighting Management Quality since 1953 w w w. n a l m c o . o rg

• Use photometric distributions to place light where it’s needed

• Additional savings by using less luminaires/equipment

Invest for the Long Term

• Partner with a reputable manufacturer that can help customers make good choices in specifications and lighting design

• Partner with a manufacturer that can supply all types of products across a broad range of applications

• Consider ease of installation to save time and more money

• When considering controls, consider if the system is capable of upgrade…or expensive to add later!

• Use common sense and invest in products that are of sound design

• Seek quality designs and components; not only easy to service but possible to service.

Saving Energy with Motion Sensors

The incredible uniformity that can be achieved with LED Area luminaires makes dimming during periods of inactivity particularly effective. Even when reducing energy consumption by 55% the site is well illuminated. The difference is imperceptible by the end-users as their eyes automatically adjust to the lower light levels.

100% Power 45% Power

The Down-side of Stand-alone Motion Sensors

Being able to “group” luminaires overcomes the shortcomings of limited stand-alone sensor range. The visual environment becomes customized to the end-users’ requirements.

Wireless Control Solutions

• Consider wireless for ultimate control• Look for easy commissioning tools

• Example: From-the-ground sensor programming via smart phone or other personal device

• Leverage grouping for sensor “group response”.• Typically dusk-to-dawn operation can be achieved by using

a circuit-level control (time clock or photocell) or by using the sensor’s on-board photocell.

The Standard for Lighting Management Quality since 1953 w w w. n a l m c o . o rg

Wireless Control Across an Entire Site

• Consider a system that is “flexible and upgradeable” (adding more light points, scheduled dimming, etc.)

• Consider a system that can be used across the entire site both exterior and interior including a broad range of product applications

• Field adjustable output controls are adjusted in the field

• Allows for easy ordering, installing and adjustment on site

Controls can help minimize the number of luminaire types required on the project schedule
