LED lighting can reduce facility electric costs by

20-50% based on which light source is being

replaced

Maintenance expenses in lighting

manifest in 3 areas:

üCost of replacement lamps and fixtures

üCost of labor to replace lamps

üWarranty protection and duration

Conventional bulbs are changed

50xbefore LEDs are changed once

Average light bulb changing time ≈15 mins

Labor cost ≈ $12/hour

Replacing 1 led bulb ≈ $3.00

Conventional bulbs are

changed 50x before LEDs are

changed once.

(50 x $3.00)= $150 for 1

conventional bulb

effect as increasing the average daily room rate by $0.62 in

limited-service hotels and by $1.35 in full-service hotels

Lighting retrofits reduce electricity by 50%

and cut cooling requirements by 10-20 %

A Las Vegas hotel replaced inefficient metal halide lights

on the building’s facade with LED lighting; this saved the

facility $41,000/annually

A Wisconsin casino saved over $221,000 in electric costs the

first year LEDs were installed, and was projected to save
