I know that no question is stupid, but this very well could be. I have a 3 set of 800w fresnels, and as I am starting to do some research on lighting, I see the importance of different intensities. With out buying another housing, I should be able to use my current ones with a 300 watt or so right? It's technically an incandescent, so it's like putting a 30w in a fixture that can handle 75w. That's what I'm trying to hit at I guess, when buying a fresnel, the wattage shown is how much it can handle right?
