I just received three flashlights from DX which I plan to convert to lasers as soon as i get the GB red LD's.

Lumiled: http://www.dealextreme.com/details.dx/sku.3329
Initial inspection / test's show that the Lumiled flashlight has a lot of potential. It uses 1 x CR123 and as a flashlight it is really nice. The driver is based on a Philips TEA1208T high efficiency DC-DC converter - datasheet found here:

A quick inspection of the circuit shows it is operating in up conversion mode. The circuit appears to be very good quality and stable. The current can be adjusted as the circuit has a current limiting pot. It should be relatively easily modified.
I have not really played around with it yet - I expect to get some time over the weekend to do so and I'll keep u guys posted.
PS. It went out of stock as soon as I bought it...I should have bought a few of them. ;D
