Are There REALLY Tangible Savings? |

Replacing lighting with energy efficient alternatives is the right thing to do. But many question what the ACTUAL
cost effectiveness is given that CFLs and other energy efficient lighting are more expensive than traditional
incandescent lighting. We have put together a few abbreviated case studies (based on actual clients) to help
you decide. See examples for a Restaurant, a Hotel,
a Large Retail Outlet, and a Residential Example below.
You will learn that savings can be significant and payback on investment is almost immediate.

- 61, bulbs totaling 3770 watts, changed to 689 watts, the numbers are calculated based on all the lights being on for 5 hours a day. This will vary as most people don’t keep all lights on at the same time. The example is to show just how much energy and money is used per year with old incandescent lighting.
