Randy Nix brought to my attention a 500W area light. The light is Flourescent consuming 65W of power while producing 500W of light. I bought two and installed them on one of my vac islands. The results are dramatic. The fixture cost me $45 per fixture including bulb. The cost to operate per fixture 12 hours per day 365 days per year is $34 per year. I decided to buy 10 more fixtures after seeing the results of the brilliant white light and coverage. This will enable me to discontinue the area lights provided by Progress Energy at at saving of $150 per month. My electrican informed me that Wall Packs are now being offerd with Flourescent bulbs. We are converting two Metal Halide wall packs to Fourescent by disconnecting the ballast and wirering direct. I plan to convert all bay wall packs to Fourescent. The 500W bulbs are $14 each, another cost savings. The fixtures can be purchased at Home Depot and Lowes. I bought from Home Depot. Also, bulbs are available in 750W and 1000W. The 1000W consumes 100W.
