Do you care about return on investment?Let's calculate based on an example project!
Let’s assume this project needs 500 pcs High Bays Retrofit.
|Traditional Lamp Source||400W MH|
|What is the quantity of luminaires ?||500pcs|
|Cost of replacement lamps in ($)||$5|
|Cost of disposal per lamp ($)||$5|
|Time per fixture for lamp maintenance (Hours)||2hrs|
|How many people are required for lamp maintenance ?||1|
|Labor rate ($ per Hour)||$75|
|What is the energy cost on site ?||$0.2|
|Lighting hours of operation per day||10|
|Operation days per week?||6|
|Lift Rental, Scaffolding Costs, Contractor Costs, Ect||$500|
|Estimated Tax Rebate Per Fixture (if available)||0|
We will use 120W HiCloud LED High Bay Light to replace 400W Metal Halide. If you don’t know how, please contact us!
Before we do the calculation, we need to know these:
Total ConsumptionThe existing 400W metal halide fixtures draw 456W (including ballast consumption).
Two PersonsUse the fully loaded labor rate. Many Harsh and Hazardous locations require 2 person teams.
Replacement TimeBe sure replacement time includes time for approvals, down time, paperwork, lock out tag out, man lift, etc.
Working TimeIf you work 8 hour shifts, don‘t forget to add an hour at the end and a hour at the beginning of the day. We often find that there is usually someone there early and late, So you want to take all factors into consideration.
MH Yearly Energy Costs:
0.456kW X 500pcs X 3120hrs/py X $0.2/kw= $142,272 per year
HiCloud LED High Bay Yearly Energy Costs:
0.120kW X 500pcs X 3120hrs /py X $0.2/kw= $37,440 per year
Yearly Saving at Energy:
$142,272 – $37,440 = $104,832 per year
MH Yearly Energy Costs US$142,272
LED Energy Yearly Costs US$37,440
Yearly Energy Saving US$104,832
So you’re saving US$ 104,832 per year. NO! You are making US$ 104,832 per year
Don’t forget that we haven’t considered conventional HID maintenance costs saving yet.
Oops! We forget to consider conventional HID maintenance costs saving!
You will agree most of projects could be paid back in less than 2 years if you have got the HiCloud LED high bay price.
