Someone mentioned, I think the OP, that the most important thing though is to get the heat away from the emitter as fast as possible. That’s why just a copper star is so effective. Surely the most bang for the buck.

That was me! Silly

Yeah, imagine a world without direct copper PCBs, where XM-L2s catch fire at 4A, and MT-G2s start to diminish in output above 3A.
It’s a distopian nightmare…

So basically what have been said is that no host is has the thermal capacity to house the XHP70 at Maximum power?

I put an XHP-70 in this light, 6V and 7+ Amps and it hardly breaks a sweat.
42 Watts isn’t exactly pushing it, but diminishing returns sets in anyway.

Does anybody have experience with this cant seem to find any info about that website and light?
Would it be reasonable to install 3 MT-G2 in this host? And what driver?

I think I have had four of them total and they are an amazing light but not really set up to do 3x MT-G2. The problem is the battery carrier is 3× 18650 so that’s a bit of a problem. The only drivers around that I know of that will function for any time at all while driving 3xMT-G2 Are Direct Drive Drivers and It just doesn’t work out with 3×18650. If you wire the emitters in series a DD driver doesn’t have enough power if you wire the emitters in Parallel it’s too much and the emitters are killed.

The Trustfire J-19 is the best light that I have worked on to make a 3xMT-G2 build actually work.

I’m a junky, I mod lights so I can sell lights so I can buy more light to mod so I can sell lights to buy more lights to mod.
