MicroBeam Flolight with 5D Mark III
 

I'm looking to pick up an on camera LED light ASAP to use with my cameras and I've heard a lot about the Flolights. Does anyone have any experience with these lights. If you're wondering, I've selected this light because I'm told that for the price, they are the best and are as close to a Litepanel light that you can get for the price. It has also been said that only lights light these can overpower the sun during outdoor shooting and allow me to properly white balance in most any situation. Am I making more of this than necessary?
