  1. The Advantages of Group Relamping

  2. 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.

  3. 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)

  4. Cost of Lighting

  5. 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 • Lamprecycling more cost effective

  6. 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

  7. Importance of Lighting Maintenance • Improved Safety and security • Maintain lighting efficiency • Optimal light output • Reduced labor costs • Increased productivity • Corporate image I

  8. 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

  9. Average Rated Life 50% lamp failures

  10. Average Rated Life Vs. Operating Cycle Fluorescent Lamp operated on Instant Start Ballast

  11. Average Rated Life Vs. Operating Cycle High Intensity Discharge (HID)

  12. Lamp Lumen MaintenanceFluorescent

  13. Relamp at 70- 80% of Rated Life • - Less than 15% failures at this point • - Failure rate increases rapidly after this

  14. 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

  15. 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

  16. 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

  17. Economics of Group Relamp • Cost for Group Relamp $7800 • Cost for Spot Replacements $2970 • Inventory Management Costs: $540 • 5% of total labor & materials • Total Cost of Group Relamp $11, 310 • Every 5 years • Annualized Cost $2262

  18. 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

  19. Economics of Spot Relamp • Spot Relamp Costs over 5 years: • Labor & Lamp Costs $12,250 • Inventory Management Costs $1225 • 10% of total labor & materials • Total Costs to Spot Relamp $13,475 • Average Annual Cost to Spot Relamp $2695
