Me too. There are advantages and draw backs to any set-up. But for me and my buck Halogens win.
They're lighter, cheaper and readily available. Bust a fixture and a replacement is as close as your nearest hardware store.

Like slim said, go with the lower wattage bulbs. The 500 just draw more juice to put out more heat.

I did see something I'm gonna hafta experiment with at Farm and fleet the other day. A flourescent that has a similar housing to a work light. The box said it drew 70 or 90 watts ( I can't recall) and put out as much light as a 350 watt halogen. It was $40 and I had one under my arm when I realized I'd left my wallet in the truck. Whew! dodged a bullet there.
