Boy, if mine works out, I'd consider building/selling you one. Might even consider building up a bunch, but dunno much bout Int'l shipping.
Edit: Didn't have time for the driver, put I have resistor mods in place, and upgraded the LED to a XHP70.2, still using the stock MCPCB - it's a good one... Wow!
7,480 lumens @start, 7,280 lumens @30 secs, 198 kcd at 5m (890 meters)
Amazing it holds the output so well.
