The Advantages of Group Relamping
Why Group 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.
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
Spot vs. Group Relamping
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
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
When to Relamp
Improved Safety and security
Maintain lighting efficiency

Importance of Lighting Maintenance
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 startHID - Average rated life based on 10 hrs. per startHalogen/Incandescent - Not affected by hours per start

Relamp at 70- 80% of Rated Life
- Less than 15% failures at this point
- Failure rate increases rapidly after this
Economics of Group Vs. Spot Relamp Example
Number of Lamps: 3000 OCTRON FO32/735 lamps
Annual Operating Hours: 4000 hours (14 hr/day x 5.5 days per week x 52 weeks)
Number of Fixtures: 1000 3-lamp Parabolic Troffers
Economics of Group Relamp
Group Relamp Costs:
Group Relamp Every 5 years
Labor Costs* $3000$3.00 per fixture X 1000 fixtures
Lamp Cost $4800$1.60 per lamp X 3000
Cost for Group Relamp $7800
* Labor rate of $15.00/hour & 12 minutes per fixture to change lamps and clean fixture
Economics of Group Relamp
Spot Relamp between Group Relamps:
About 15% failures or 450 lamps
Labor Cost* $2250$5.00 per lamp X 1000 fixtures
Lamp Costs $720$1.60 per lamp X 450
Cost for Spot Replacements $2970
* Labor rate of $15.00/hour &
20 minutes per lamps replacement - includes time to carry ladder from
storage, get new lamp, replace failed lamp and return ladder
Economics of Group Relamp
Cost for Group Relamp $7800
Cost for Spot Replacements $2970
Inventory Management Costs: $5405% of total labor & materials
Total Cost of Group Relamp $11, 310
Every 5 years
Annualized Cost $2262
Economics of Spot Relamp
Spot Relamp Costs over 5 years:
Labor Costs* $8625$5.00 per lamp X 345 lamps replaced per year on average** X 5 years
Lamp Cost $3625
$2.10 per lamp X 345 lamps/year X 5 years
Labor & Lamp Costs to Spot Relamp $12,250* Labor rate of $15.00/hour &20 minutes per lamps replacement - includes time to carry ladder from storage, get new lamp, replace failed lamp and return ladder
** Based on lamp mortality curve it would take 10 years for all the lamps to fail - about 15% of the lamps would be replaced twice - 1.15 X 3000/5 - 345 lamp failures per year
Economics of Spot Relamp
Spot Relamp Costs over 5 years:
Labor & Lamp Costs $12,250
Inventory Management Costs $122510% of total labor & materials
Total Costs to Spot Relamp $13,475
Average Annual Cost to Spot Relamp $2695
