You'll have no problem putting a 200 watt bulb in a 500 watt socket. Just like household bulbs. You can put a 50 watt bulb in a lamp that had a 100 watt bulb in it. The other way to reduce light is to move it further from your subject.

If your lens aperature is at F8 and the lights are 5 feet from the subject and you move the lights to 10 feet, your aperature will be F4. You lose 2 stops of light.
