It has the efficient TIR/reflector zoom mechanism(supposedly the same as LEDLenser lights). This zoom mechanism is suppose incur much much less lumen loss vs aspherical only designs. But like all these TIR/reflector zoomies, the driver(or the lack of) and emitter totally sucks. Wondering if that single CR123 Nu-Flare can be modded to a XML-2 with good 3 mode driver(max ~2.3A). That would be my dream every day carry pocket torch.
I don’t have that light, but if it really does have the same zoom mechanism as an LEDLenser then you may have a problem.
The LEDLenser mechanism works by having the LED mounted on a post. The lens then retracts around the sides of the post. There’s very little lumen loss because in both flood and spot mode all of the sidespill goes into this wraparound lens.
That small zoomie almost certainly was not designed to work with an XML2, and as such both the post and the wraparound lens would likely not be the right shape for such a large LED. Also, heat transfer down a relatively small post may be much less efficient than for an LED sitting flat on a conventional star so running such a light at 2.3 amps could be questionable.
I see, 18650 told me the same thing, so recommended a possible XP-G2 mod… Thanks for the input!
I thought 2.3A is possible because that is about how much my S10 Baton draws on a XML-2. The S10 is even small than this Nu-Flare!
The S10 has a conventional star so there’s more metal close to the LED to help transfer heat away from the LED. With the LED mounted on a raised pillar like on the LEDLenser it’s going to be harder to transfer heat away because there isn’t the mass of metal close by.
This could be a complicated mod if the existing pillar won’t fit your new LED. The Modder would have to get creative in fashioning a replacement pillar.
