Here's another LED lighting product coming out of the Fotodiox company. The FlapJack panels use an array of LED lights that sit only at the surrounding edges and point inwards. The result is an extremely soft and diffused light source without hot spots or multi-shadow issues that can be placed very (very very) close to your subject. Here's a little demo video below.
I've actually reviewed a set of similar lights from Rosco several years ago, and my experience was that they were a very effective diffused light source, but weren't extremely powerful and had a slight color cast. Of course LED lighting has changed dramatically over the last few years offering more output and higher quality color reproduction. Combine that with cameras that actually require less lighting, and these lights may be a great item in the bag since they don't require any light modifiers or diffusion.
Hopefully i'll get a set to test out at some point and also run it through my handy iPhone Bluetooth Light Meter for some test results. More information about the new FlapJack LED lights can be found at the FotoDiox website (click here).
