I found that the LED lamp also works well for photography.  Here are some pictures showing the set up that I used.
The light and umbrella are sort of cobbled together, but it worked.

The graduated background.  I have a sheet of Formica and 1/8" Baltic Birch plywood to create a curved sweep.  I use white and black pieces of foamboard to modify the light.

I have my camera about ten feet away on a gimbal mount.  I'm using a 70 - 200 mm lens which covers most things without needing to move the camera position.  The two targets ae a WhiBal white balance card and an X-rite Passport for creating custom color profiles.

Anyway, I really like the LED for photography.  It beats the heck out of the 500 watt photo floodlights that I have been using.  My latest piece in the gallery, Celebration Basket, was shot with this set up.
