CofunKool Super Bright 64 LED Light Panel On Camera Light/Camcorder Video Light for Canon,Nikon,Panasonic,Sony,Samsung and Olympus Digital SLR Cameras (Battery NOT Included)
This little light surprised me, it's very bright. Has great output and can be enhanced even more by the removal of the filter. It uses 3 double A batteries, but don't let that dissuade you as it last around 4 hours on high.
