I could be wrong here and I guess it doesnt really matter but a Lux 5 is not made by prolight. Prolight is a brand of LED and Luxeon is a different brand. But they do both have 5W LED's. Anyways here is what you can find from using the search function.

Most of us are waiting for the K2's as they need less cooling than a 5W but are around the same brightness.
