I see. Do you think the current 6A driver would be fine with the emitter? Will it overdrive a single LH351D? I see that in Sofirn lights, the max current drawn by this Led is about 3-4A, which is about 1,300 lumens. Wonder if Simon has to make some new drivers just for this.
I had the same host, with bypassed springs, and LH351D with a Mtn FET. I went on walks and otherwise used it for a few months with high drain cells. No angry blue.
But, I did switch the LED out of the C8+ for a 6500K SST40. From what's being highlighted here, I'll be fine with running the LH351D at a safer amperage.
I noticed that Gearbest has some sand colored product but anything other than the two colors, I'd ask Simon about their authenticity.
For a XHP 50.2, It'll handle the heat for a little while at turbo but this having a throwy beam, you don't have to run it at turbo to light up the target really well. Go with a 3 volt emitter.
