What emitter is this?

It is a 3v led, if that helps.

And what should I put in its place? I want warm to neutral white, and a large emitting area (MT-G2 would be ideal, but it is 6v and I don’t want to driver swap this thing). I realize I will probably have to focus/spacer the LED/MCPCB due to how high the stock LED is currently sitting.

SSC P7?

With the new LEDs like XML2 you need anyway a lot more current

I would say this LED is not driver hard, maybe 500mA

CRX , you are right , is a SSC P7 , and could be driven at 2800mA but at 4.2V ! ( max. 900Lm ) , having an efficiency of around 90 Lm /W...

How does it compare to the XM-L2?

P7’s are ten year old technology. XM-L2 leds are more efficient at the same wattage levels.

I figured. Just asking for knowledge’s sake.

Yes it is, I had one in a Mag light several years back

I put one in a Nuwai Q3 when they first came out and it rocked in that tiny single 16340 cell light.
Times sure have changed for the better.

P7’s were very popular for modding when they came out. I had several friends have me make them P7 lights for hunting, law enforcement, edc. 90 LM/W was powerful back then, with excellent color and throw in a long, deep reflector. Ii have a few in my collection. My favorite is a P7 in a HS-802 host.

SSC P7, i still have that light on moded maglite.

You would probably get around triple the output by just swapping the emitter to one we use today

this is SSC P7

Why don’t you try de-doming it first? Remove all this translucent gel.

De-doming this type of led is a real challenge !...The eight wires that are connected to dies , are long ( compared with XM-L's ones ) , and acting as the reinforce in concrete.., I tried once but failed , reaping apart the wires...( I have to say that my rate of success de-doming is close to 100% , even with SST50 and SST90 !)

I suggest to try first on a dead one , to see how is acting , and I assure you that you'll never try again , on a good one ..!

I used the P7 for about a year in that old Nuwai Q3 but eventually switched to a MC-E with a 20mm IMS SMO reflector for a better overall beam.
The introduction of the P7 and MC-E were game changers for all the incan flashlight manufacturers in 2007 and 2008.
The landscape was changing and they became followers rather than leaders in such a short time.
Paradigm Shift for flashlight tech.

Excellent ! I like it
