I read it at last month before. /ubbthreads/images/graemlins/smile.gif What I can tell is that some new headlamps and flashlights are coming with this LED.

Seen any lifetime datasheets on their products?

I have most of the heat management and lifecycle info on their products. I'll try to post them as requested as they are detailed and product specific but for the most part they are rated at 50k hrs at nominal. Seoul is the company we have been working with on the earlier mentioned products we were looking for power supply's for. I have a meeting this week with one of their R&D guys if any of you have specific questions you would like brought to the table.
One thing we have found with their 5 watt is the heat issue. Luxeon puts out considerably more heat than the Seoul products in 5 watt. Not sure why but its important in our use. We also like the beam spread better of the Seoul without the lens. With the lens it has problems with being able to see an obvious 4 shadows in the beam caused by the 4 die in it.
