Crelant 7g5 turned monster

So last night I was fiddling around with my 7g5 that was having some non contact issues on the negative path, while surfing around I found mention of saablaster running a XP-G-2 on the TN31 driver.

I just happened to have a XP-G2 LED on a 10mm star sitting on my desk so I thought “why not” since the 7g5 is under driven to begin with and it would be a good excuse to order an XM-L 2 if it didn’t work out.

Swapped it out pretty easily, just had to sand the star down to 1.6mm thick (my 10mm star was 2 mm thick vs the 1.6 for the one I got with the crelant) soldered it on and let me tell you, it’s a beast.

Side by side it throws at least as well as my TN31, the spill seems nearly as bright.

If you have a 7g5 it seems to be a very worthwhile mod, I think I’ll use mine a lot more now that it’s lux has doubled.

Wow, nice mod!

Just wondering, what’s the stock current?

I don’t remember, I actually toasted the current function of my DMM, but I do remember it was around or under 3 amps.

Not really very scientific, more along the lines of latenight desktop tinkering than anything.

next step might be to dedome one and put it a k40 host.

Thanks for your reply.

Enjoy your throw monster!

The way I see it, a dedomed xpg2 should triple the lux of an xml light, if the tn31mb is any indication.

Is it easy to dedome an xpg2? i was going to pit an xre in my thrower, but would the xpg2 beat it?

I’m also really interested in the answer to this question… Subscribed

Only LEDs I have any experience dedoming are XR-Es (the cheap crappy ones, not EZ900s) and XM-Ls

I found the XMLs easier to dedome after shaving them down, quite frankly I prefer them just shaved, a full dedome drops the output a lot and makes it far too yellow for my liking.

The XP-G2 dome seems to be pretty soft and it has very short bond wires, both of which should make it pretty easy to do, I don’t have another one on hand so I’m not willing to risk bricking it.

EDIT;

After thinking about it for a few minutes I’m also not convinced it would be such a great idea to run one of these on an XML driver without a dome.

The whole point of my post was to say that on a conservatively driven XML light it’s a drop in swap that doesn’t seem to lose much in output but grants a pretty big bump in lux.

Is your 7g5 v1 or v2? I wouldnt think my 7g5 v1 is under driven at all. Sounds like a cool mod though.
