I'm looking for video lights. Must be low cost, portable, "daylight" color, and have a fast setup and take down. This means those ultra-cheap CFL based soft boxes can't work because of the long set-up times I might have the DIY some LED panels. I find I can buy a 300 LED daylight (6,000 Kelvin) LED strip for $20. I might get some and glue all 300 LEDS to a 30 x 20 inch white foam core board. I would have to find some way to attach barn doors (and keep them in place) and experiment to see is diffusion is required. But maybe there are already something like this available?
