I had my local electric utility do a lighting audit on some of my locations. They have programs that will replace metal halide lights for more efficient CFLs. They pay 60% of the total cost of the new lights and labor. They also replace all T12 bulbs to the better T8s. In my SS bays I use 2 250 watt MH and one 400 watt MH. We have decided to replace the MH bulbs in each bay with 5 42 watt CFL wall paks. They have 2 SS bays done with the CFLs and 2 that are still MH. From the street at night you can not tell which is which. Inside the bay my guess is that you have about 90% as much usable light with the CFLs while only using 1/5th the energy. The energy savings per year is enough to light 3 homes a year per location. Projected energy savings for me is about $158 per month. I will update as work progresses on the upgrade installs.
