I use the TL-50 by Torchled which works very well. I put it on a mini tripod so I could put it anywhere on the floor. Its great cause of the 1/4 20 threads you can mount it anywhere, with a clamp, on top of camera etc. I bought it off amazon after I saw it in a review. It is Made well and has really bright output better than what I have used in the past. The battery that comes with the unit lasted me over 3 hours, and the accessories that come with it serve justice as well. Neat LED product.
