Many videographers are out to get the brightest LED light for the money, which makes sense, but you also need to consider diffusion such as a softbox, scrim, reflector, umbrella, etc.
Alternatively, Fotodiox has come out with a series of lights called "Flapjacks," which are very thin of course. But more importantly, they're designed to be used without any kind of diffusion, which makes them perfect for small spaces and quick setups.
In the Flapjack lights, the LEDs are positioned on the outer rim of the casing, facing inward rather than out, which diffuses the light into a large source.
The trick with these lights is they're not as bright as other LEDs out there, but when you add any kind of diffuser to a bright LED panel, you're cutting the light by at least half (1 stop of light), or more.
The Flapjacks come in a variety of sizes, but we're particularly interested in the Studio XL, which is their largest at 32", to use as our main key light on interviews and shoots where we can throw it in the back of a car, rather than shoots where we have to fly.
Update: We now have a Studio XL in hand, and are giving it lots of use before we write a review about it. Stay tuned!
