The item description of the Osram KW CSLNM1.TG is not accurate, as the LED can not forward 5000 mA, but only 3000-3300 mA, corresponding to the datasheet published by Osram. The light beam is larger than the one of Convoy S2+ with SST20 and does not seems to be more stronger, as I expected (just a little stronger). The worst thing is the fact that with this LED the flashlight heats up about 4 times faster than my old SST20, at the same power consumption! For now, I feel like I bought another SST20 but defective, because it heats faster, with a not so regular light beam center. For now, my favorite small flashlight is still the old Convoy S2+ with SST20... On the pictures the flashlight with the Osram KW CSLNM1.TG LED is on the right side, the SST20 in the left side.
Well, I must admite that, despite the fast warming up issue, it is a flashlight of a very good quality. I think it deserves four stars, but I can not modify the first feedback. Also, it is ok for the price.
The OSRAM W1 LED gives a nice throw for such a small flashlight!
