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 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
