LED PAR RECESSED FLOOD R.O.I.
BRIEF
COST COMPARISON TOTALS
Converting to LED lighting gives RETURN ON INVESTMENT in 3 ways:
ENERGY
–Less power consumed. (11 watts vs. 90 watts)
MATERIALS
–NO bulb replacement costs over at least 5.7 years.(This equates to 50,000 hours running continuously 24/7)
LABOR
–Maintenance and/or operational downtime costs saved over life.
Please note: We have not included the LABOR SAVINGS FOR THIS COST ANALYSIS, however, our
clients have found significant warehousing and labor savings well beyond expectations.
Using a premium quality PAR 38 halogen LAMP with a maximum life span of 2500 hours, you will need
20 bulb changes over 5.7 years. For an accurate cost analysis please feel free to estimate and add your
labor costs for changing 20 bulbs. (See ENERGY and MATERIALS costing below)
MATERIALS
-Traditional PAR FLOOD Halogen 90 Watt bulbs last 2500 hours.
-Standard PAR 90 Watt bulbs are approximately $7 in bulk supply.
HALOGEN PAR FLOOD
……24HRS /DAY…$7 divided by 104 days..…$0.0672 or 7 cents PER DAY MATERIALCOST TOTAL.(104 days = 2500 hrs.)
…..$25.55 MATERIAL COST / 1 YEAR
-A DIVVALI L.E.D. RECESSED FIXTURE using 12 Watts of power is our proposed direct replacement, fitting
neatly inside the existing fixture, or replacing it entirely as may be desired.
-Cost - $95 USD.
- A DIVVALI L.E.D. RECESSED FIXTURE TOTAL LIFESPAN is 80,000 hours. At 50,000 hrs the LED unit will
still be 70% of its original brightness (30% reduced).
-For purposes of this comparison 50,000 hours and 70% of original brightness will be considered the
end of usable life. It should be noted that traditional PAR FLOOD Halogen bulbs lose 30% of their original
brightness in the first 1/3 of their life span.
L.E.D
…24 HRS/DAY…$95USD divided by 2083 days...$0.0456 or 5 cents PER DAY MATERIAL COST TOTAL.(2083 days = 50,000 hrs)
…..$16.64 USD MATERIAL COST / 1 YEAR
ENERGY
(One KWH is 1000 watts used for 1 hour, or 1 watt for 1000 hours)
- Quebec’s 2008 publicly available statistics on power rates for major North American cities show:
9.08 cents per
KWH average cost for OTTAWA ONTARIO ‘L’-size clients.(Source:

HALOGEN PAR FLOOD 90 Watts– ENERGY COST FOR ONE x 90 WATT LIGHT
90 Watts x 24 hours /DAY= 2160 Watt-hours or 2.16 KWH /DAY
365 DAYS/year x 2.16 KWH = 788.4 KWH per year.
9.08 cents ($0.0908) /KWH x 788.4 KWH (one year)
..... $71.59/YEAR ENERGY COST / 1 YEAR
L.E.D. RECESSED FIXTURE- ENERGY COST FOR ONE x 12 WATT LIGHT
12 Watts x 24 Hours /DAY= 288 Watt-hours or .288 of a KWH / DAY
365 DAYS/year x 0.288 KWH = 105.12 KWH per year.
9.08 cents x 105.12 KWH (one year)
….$9.54/YEAR ENERGY COST / 1 YEAR
Labor / Maintenance cost for non-LED bulb replacement
