Bowhunt, I will throw something out there and you can take it or leave it, but I use the same generator as you have and instead of usingfive 500 watt bulbs, you can use GE Ultra 350 watts, have nearly the same amount of light per bulband be able to use 6-8 lights now without straining your generator any more. The difference and advantage7 GE Ultra 350'svs. yourfive 500 watt bulbs will be quite significant.
