said by Subaru:what was the lamp? CFL? being 7500W a small lamp is hardly a load, however I noticed most CFL's will flicker with on a generator, I did not have the right meter with me but I guess it's the AC cycle and if it's not a inverter generator that would be the case as well, but it's nothing to cry over.
Instead of cfl's, I took the LED bulbs out of the hanging light in the kitchen and used them in a torch lamp during the outage. They were stead, bright, and drew very little wattage. I'm sold on the Philips LED bulbs - just have to get the cost down a bit ...
