Hhmm, I'm reading this thread, and I don't understand... I thought the K40 is exactly a TN31 - same driver, same UI, same everything accept for the styling around the head? Well maybe, maybe not - ThruNite says the TN31 XM-L2 has a XM-L2 U2 1C tint, not 1A. The manufacturer quoted #'s are extremely close, extremely... Even the odd discrepancy between the quoted throw distance and kcd #'s.
If this is a true TN31 clone accept for style, then this thing throw's like 140-150 kcd or so -- the 95 kcd is simply wrong, just like it's always been from ThruNite. The distance is the close to accurate # while the kcd # is from who knows where?
Also 3 amps should be totally wrong -- it's closer to 4 amps and at least 3.5, just like the TN31 -- same driver I thought -- in a TN31 mod thread, I thought someone posted a pic of the K40 driver and it was identical? Also, the TN31 XML and XM-L2 use the identical driver, I mean identical exactly.
Am I missing something here? I got a stock TN31 XM-L2 at home right now so I can do a quick lumens and throw check on it for comparison purposes...
If it match's up well with a TN31, then I'm in for one for sure - one resistor mod, de-domed, wire/grease upgrades and you can get 350-370 kcd.
