I thought the TIR might be an issue. A pity though, I quite like the M2R Pro and I would love it with a good LED.

KD got a few 80 and 90 CRI XHP35’s but who knows how good they are.

I already put one of those 90 CRI ones in my M2R Pro. They are loads better than the original, but not as good as this LED.

Damn it. This just put the T2 on my wish list.

I’m wondering if there are any optics suitable for this emitter and other xhp35 lights like the M300 and Klarus E3. The E3 is particularly attractive to me in form factor as a slim 21700, deep carry, and tail switch design.

I sent Maukka 2pcs 4000k in the production batch for him to test, and here's the report for both pieces:

 

 

 

Summary: Slightly above BBL, but not wildly out of control. This report suggests that the stock I have is very different than the ones tested in the L6 FC-40 thread.

 

At 3 A: +0.0015/+0.0019

 

At 1A: +0.0023/+0.0026

 

Note: The sample is presumed to be tested without lens. Most AR-coated lens will bump the duv values by about +0.0020.

Where we can get datasheet? Thats from FC60 datasheet, but im pretty sure its the same because both rated same 12-14V.

I have my own FC-40 datasheet, but it's for the regular 70 CRI parts. The voltage curve should still be similar, though it's rather sketchy.

Does anyone know of a good 12V e-switch boost driver, like 25-26mm ish in size? I want to put one of these in an Astrolux FT02 XHP70.2 version, but the driver is dead and I can’t get one from Mateminco.

So, I can guess this GB never happened, didn’t it? :/

It partially did (for 4000k only).

Do you still have any of the 4000K a available? If so, would it be possible to ship to Canada? Thanks

Will this fit in a Sofrn SP33S? I'd be curious about how difficult it would be to replace the XHP70.2 in that light.

The emitter should fit, but the problem would be finding the right driver. Most of the XHP70.2 are 3/6V variants while 12V ones are less common in flashlights. I have no idea of which version SP33S is using, but I have a hunch that it might not be 12V.

Thank you. You're probably right. It uses a boost driver, but I haven't seen specs on it. The may implement a 3V LED and a 6V boost for all I know.
