Actually, I have a previous version of this 1000 watt continuous light from Steve Kaesar. As I use strobes for my photography (much better than continuous light in my opinion), the continuous light only gets used when I'm doing video. It works well in relatively small rooms, however, I'm sure it would help in a large room if you use an umbrella instead of the softbox (I recommend the softbox kit, though, so that you have a good, close-quarters light modifier for video). Keep in mind that the continuous lights can be very bright and can get very hot, so you don't want them terribly close to your audience.
