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

Thank you for the offer, but it's one I've been meaning to buy/try anyways. The one time I go to illuminationsupply to order it though, and it was out of stock. Haven't checked in a few weeks now, so maybe back in stock again.

Np. I think it would be fantastic in a mag with a rebel reflector. I plan on building one shortly, as soon as I get done with the copper mounted tests - gotta know how hard i can push it!

Thank you Match.

I’m waiting for mine from cutter.com.au too :wink:

Was that with the incan or rebel reflector? Also, I do plan on making a hot-rod P60 with one of these. My plan is to use the SF xpg reflector (best one I've seen for xpg), along with a custom copper heatsink that perfectly fits an L2P host with the emitter directly mounted to the copper. I just need to run the copper mount test first to find out the appropriate current. Most likely I'll settle at 3 amps, which will mean the same runtime on max as an xml, but with a lot more throw. Time will tell...

Yeah, just what I thought :smiley: That Nanjg 2.1A driver from IOS will be a perfect match :bigsmile:

these emitters look very interesting .. looks like it takes some amperage to make these lights really shine ..the increase is impressive ..I've always been an xpg fan .....I need to see what kind of throw they have and what it looks like in real life ...neutral of course

Someone on CPF bench tested this emitter and (IIRC) at around 4.5A he saw 850 lumens. Very curious to see what you get when you push it hard.

Wow

thanks for the test ,hope will find them soon on 14mm pcbs.

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
Matt

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!
