Is this beam coming from a surefire l2 head with XPH70? I'd love to see a picture of the light
Nooooooooo. That was a Convoy L2. Sorry if I got ya excited [emoji23]

I'm glad you cleared that up. It is confusing when you posted that picture in the Surefire Mods thread...Nooooooooo. That was a Convoy L2. Sorry if I got ya excited [emoji23]
Since a Kroma is similar to a U2 can the emitter & driver be upgraded?
Can you please update pics for U2 xhp50? Thanks, Mike
Can't see pictures alsoAre they not showing up?
Can't see pictures also
New ones. I can only see beam shot you edited pic!The new ones, or the XPH-50 mod?

Yes sir got them now. Cool pics thx!!How about now?
Not visible.
Can you please post photo how xhp50 is mounted in U2? I have MC-E modded U2, but I would like to put other led into that.

I was not sure how this would turn out in such a shallow reflector, but I can say that the XPH50 in an L2 is awesome! Now I need to find one of these gems for my own.
Interesting note: I did not have any non rechargeable batteries to test the L2 and was not sure if they would smoke the circuit or not. A quick "Google" and many CPF'ers using IMR123s and I just had to see what this thing was like. All I can say is, WOW! With IMR batteries this sucker pulls 3 amps and put a huge smile on my face, and after a minute was a nice hand warmer. I'm not sure I would run this wide open like this unattended but it was insane!
Even at 1.3 amps Cree's product characterization tool says the J4 bin XPH50 puts out 1200 lumens at the emitter, and at 3 amps that goes up to a whopping 2375, again at the emitter. All that with a tint that, IMO is beautiful.
I have a few photos and did my best at two beamshots. The were underexposed -2 on low and high with regular cr123 batteries at two feet for the low, and twelve feet for the high to show that it has absolutely no donut hole. From inches from the ground to as far as I can see the XPH50 does not have a donut in any light I have modded unlike the Cree MC-E, or the Easywhite XM-L. This is one of my favorite LEDs.
Cool post.
I've got a NOS L2 on its way and had been finding old MCE upgrade posts that looked great and when looking at LEDs decided on a 5000K high CRI XHP50 (also on the way) thinking I might be the first before finding this post.
Sounds like I've chosen well.
What size PCB did you use? I've ordered 10mm.
Did you need to make many or any adjustments to the heatsink and/or PCB?
I'll be doing this mod in a few weeks so any tips will be appreciated.
Another question,
I don't suppose you tried running this on a single liion like the keeppower 16650? I'm hoping the boost driver works well with the XHP50 and 16650 battery as I don't want to use 2x16340 or CR123.
That would be a negative. I have a 16550 and just tried it in L2 and it does not work as expected. The only way to make it work with the XPH.50 would rebuild it with a boost driver and machining a new copper pill would be a must when running the XPH.50.
Thanks for the reply.
Are you saying that the stock driver isn't a boost driver?
I had read in old posts that it boosts the voltage to about 6.4V from 2xCR123 (which have a resting voltage of about that anyway) and even boosts a single Li-ion to 6.4V? I think they were using a 14670?
From what you're telling me it sounds like the driver might vary.
Thought I'd post here rather than PM so others can benefit from your knowledge.
Thank you.
I stand corrected! It does work off of a single cell. I did not realize the 16650 I had was at 3.8 volts and the L2 did not turn on. I used a freshly charged rcr123 and it does light up so, 1 cell will work with the stock driver but the XPH.50 will not see its full potential but will be a large improvement over stock.
