Based off of the same body that can be powered off a single Sony NP-F style camcorder battery, the 312 / 508 / 876 LED Video Lights can offer truly 'off-the-grid' shooting using some of the cheapest rechargeable batteries available.

I recently received the 876 LED Video light to test out, so I thought i'd put them side to side against the smaller siblings. You can see how much brighter and how much more diffusion is available as we get to the larger panels, but also a noticeable shift in color bias. If you're trying to mix these lights with other LED panels or ambient light, then these tests will show you how they perform.

Here's a snapshot along with specs from an LED Meter.

The images above showed the light 7 feet away from the wall. These readings (below) were taken just 3ft away from the light. (note: The 312 is a bi-color version, so it will have less output than a 312 full daylight version). Click Light Meter image for larger view.
