Larry, I got what you say about 500w not being all that much. However, thats one of the advantages I see with hot lights. When I want to shoot at f1.2 or f.18, I'll grab the hot lights rather than the strobe. I can shoot at the wide apertures and blur the background even if its only 5' from the model. I can't do that with my stobes since I can only dial them back to 1/64th power, which is still far too much.
Tim, There is that cost advantage between the two. But on the bright side, using the continous lighting will give you an edge in the end IMO, It is harder to work with, so you learn some excellent techniques required to work with them effectively which also carry over to using strobes. And, it puts more 'tools' in your lighting tool kit.
I also think the heat aspect of the lights are over exaggerated by some. I've heard sweating bullets, melting models, squinting, etc, but I have yet to have any model complain of any of those things. If you are very close to the light and its direct, yea, it will be hot. But diffused through a light panel with the model 6' or more away, they are unaware of any heat issues at all.
I use them when it makes sense, like any other light source including the sun, available light, hot lights, strobes, flashlights, etc [img]/ubbthreads/images/graemlins/smile.gif[/img]
I posted these images in another thread on home depot lighting, so I apologize if its redundant here for those that read both threads. These were done with hot lights, some with and without panels.
