More Emitter Test Results (xpg2, xpe2, mtg2) Updated 11-12-12

Thanks for doing this match. I love real world technical data.

Match ...............where the rubber meets the road .

If you do, please take before and after beamshots :slight_smile:

Thanks Match,

your led ‘horsepower curves’ are some of the most important light info out there!!

xp-g2 @ 2A = killer!

Really interested in the XP-G2. I have an XP-G p60 driven @ 1.4A. I really like it, and the XP-G2 sounds even better :bigsmile:

I read over on cpf, one of the traders who sells p60’s measured xxx number of lumens driven at 1.4A for the XP-G2, and output only fell by something like 7-10 lumens after several minutes running.
Then an XP-G2 driven @ 1.75A measured more lumens initially, but output fell to the same level as the 1.4A p60 after a few minutes run time due to heat build up.

Have these results been seen here in testing too?
I’d really like an XP-G2 p60 driven at 2A, but wouldn’t want to if its output fell after the first few minutes.

Cheers

Hi Bob

Yeah, 100,60,20% sounds good.
I have my 1.4A XP-G s2 in an Lop reflector and i really like the beam. I’m looking for something similar but more lumens.

Cheers

I don’t think I’m capable of doing it but I’ve asked E1320 to have a look at what can be done, he’s pretty busy right now tho…

Perhaps I’ll look at doing the Ultra OK for now as I don’t mind cocking that one up, I have a spare lol

Pretty sweet data, the XP-G2 is pretty cool, still trying to see one in person though, lol.

BobK,

Excellent report on the xpg 2 P60. What specific reflector did you use? I've noticed this makes a big difference with any emitter. For example, the smooth reflector on the MF UF 3-mode xml blows away the generic smooth reflector that comes with most drop-in kits. Same goes for the smooth reflector from the SF low voltage xp-g drop-in...I wish I could buy just those reflectors.

I'm currently going through the various supply sites and seeing what's out there for xp-g specific reflectors (Much like the xp-g reflector in the SB s-mini...dang near perfect beam for the xp-g2).

I’ve got an XP-G2 running in a Dereelight P60 XP-G/E SMO reflector (with the emitter-side bored open slightly) and after some height adjustments, it gets a nice and tight beam.

I’ve also tried the XP-G2 with the SMO reflector from a Solarforce 0.8-4.2v XP-G module but it does not want to focus at all. Weird, considering how well it does with the XP-G.

Hope this not posted in the wrong section but does anybody know where I can get one of these in a drop-in? I don’t think Erik has any of these yet. I have tried Manafont and Kaidomain but with no results. I have a UF WF501b light that has a dead xenon drop-in and would love one of these XP-G2 drop-ins in it. Thanks in advance.

Awesome info, and exactly what I was looking for. Looks like I'll remove two 7135's from my 105C and run it at 2.1 amps on high in my Mag with Rebel reflector. Thanks for this data Match!

Where are you guys buying your XP-G2’s? I’ve been looking for an outdoor white and can’t find any.

just waiting for triple XP-G 2 stars to become available. Hopefully someone will start making those!

I just got one from www.illuminationsupply.com. I don't even know what tint ;)

Man, there are a lot of people from WI on this forum.

Iternational outdoors is where i got mine at.

Put one in KD small hole reflector empty dropin module and the beam is nice. Driving with a KD V2 2.2a driver. Its a nice bright setup. Gets warm pretty fast in my L2m running SF protected blue and white. Definately recomend that setup. I have one more xpg2 and going to try it in a big reflectored light just havent decided which one to try it in. Maybe the Jacob A60, or maybe the ebay ultraok 57mm head.

Cutter.com.au is the only place I’ve seen that has R4-5B Neutral White bins in stock at the moment, but shipping’s gonna be killer.

I see those at cutter, but the shipping is three times the led price. :open_mouth:

Group buy .... I'll take 3

5B is the tint I want :)

I’ll wait for the NW or WW to become available from Ill. Supply, shipping is too $$$ from Cutter.
