Transcript Relamp vs Spot - Association for Facilities Engineering

The Advantages of Group Relamping
Spot vs. Group Relamping
Why Group Relamp
Group Relamping is crucial to a successful lighting program aimed
at getting the optimum light output at the most effective cost.
The more lamps burn, the less light they deliver.
Vs. Spot Relamp
Lamp replacement on an as-needed basis, only after lamp has failed
Spot Relamping labor cost is generally 5 times greater than Group
Replacement labor costs.
Cost of Lighting

Initial Investment/Considerations

Materials: The cost to purchase lamps, luminaries, ballasts &
wiring
• Lamps: Consider efficacy (LPW)
• Ballast: Choice will effect power consumption and light levels
• Fixtures: Ability to deliver light where needed?

Operating Costs: The electrical energy costs to operate the
lamps over their life

Maintenance: The cost of replacement lamps and ballasts,
and installation labor costs to replace burned out lamps
• Labor to Install: Dependent on fixture type and number being
installed

Electricity = Lamp Watts X Rated Lamp Life X Cents per kWh
(Kilowatt Hour)

Importance of Group vs. Spot Relamping
 Lighting System Maintains Higher FC Levels
 Reduced Labor Costs
.20 Minutes/Fixture - Sport Relamping (Higher Hourly Rate)
vs.
.03 Minutes/Fixture - Group Relamping (Low Hourly Rate)
 Fewer Work Interruptions to Replace Spot Failures
 Labor slated in off peak hours
 Lamp to Lamp Color Uniformity
 Light level uniformity
 Less Inventory
 Lamp warranty tracking easier to administer
 Lamp recycling more cost effective
When to Relamp
 Fluorescent: 70-80% of Rated Life at Given Burning Cycle
 Incandescent/Halogen: 85% of Rated Life
 HID:
 Metalarc - 70 to 80% of Rated Life at Given Burning Cycle
 Lumalux Plus - 70 to 80% of Rated Life at Given Burning Cycle
Importance of Lighting Maintenance
 Improved Safety and security
 Maintain lighting efficiency
 Optimal light output I
 Reduced labor costs
 Increased productivity
 Corporate image
What Are the Primary Light Loss Factors?
 Lamp Lumen Depreciation (LLD)
 Lumen loss over time due to lamps
Fluorescent: Degradation of phosphor
Incandescent: Gradual evaporation of tungsten electrode material, depositing on the bulb wall
HID Lamps: Consumption of the sodium or metal halide salts in the arc tube over life
 Luminaire Dirt Depreciation
 Lumen loss over time due to dirt accumulation on lamps, luminaires and room surfaces
 Failed Lamps
 Dead lamps and lamps approaching the end of their lives can cause substantial light losses
 Average rate life of any group of lamps is wh4en 50% have failed
Fluorescent - Average rated life based on 3 hrs. per start
HID - Average rated life based on 10 hrs. per start
Halogen/Incandescent - Not affected by hours per start
