I bought the Fifthunit/DealExtreme version a couple months ago to have as an emergency light or possibly as a camp light. I have not used it for either purpose yet but from the initial "first light" tests I find the direct light from it very harsh and distracting - especially if the LEDs are in the line of sight which is unfortunately how it is designed to be used. It works OK with a ceiling bounce or basically any position that keeps the LEDs out of direct sight like putting it on top of a fridge or using the hanger in the opposite way than it was designed. I would not want to use it on a table, wall, or floor of a tent without a diffuser - an empty margarine or cottage cheese tub should do the trick.
A couple other observations on the DX version: On the plus side it has a couple magnets that will "just" hold it to the side of a fridge or side of a car. On the negative side, the build quality is low – but for around $7 shipped it was as expected.
