What Happens ...What Happens ...

… to any lighting system?

Lamp performance deteriorates

Dirt collects on fixtures and lenses

System components fail

Lack Of Maintenance Will:Lack Of Maintenance Will:

Reduce illumination by 25% or more

Negatively affect performance,

space perception, safety and security

Waste energy by

giving less light for

the same energy dollars

Causes Of Light Loss:Causes Of Light Loss:

Lamp mortality

Ballast mortality

Dirt accumulations

Luminary surface deterioration

Failed system components

Room surface dirt accumulation

Lamp MortalityLamp Mortality

• All lamps have specific

mortality curves

• Rated life is usually

based on 3 hrs/start

• At rated life, a cumulative

total of 50% of lamps

have failed

• Burnt-out lamps can

cause rectification and high

ballast current - increasing

cycle

Recommended annually for outdoor fixtures

and signs

SummarySummary

Spot lamping is the least cost-effective way to maintain

your lighting

Typical “relamping service” from janitorial contractors is

basically just spot relamping

Janitors and other trades people are less

skilled and efficient than lighting professionals

Proactive, planned maintenance

programs enhance your facilities

and save electricity

Programs can be planned during

building design to reduce initial costs
