I put an Optisolis LED into a modified AA flashlight. I had a leftover 4000K Optisolis that I got from eurekatronix last year. I saw the 16mm copper MCPCB for nichia 276A on the Convoy website and it looked like a good fit.
I reused the single mode AA driver which produces 350mA.
Overall the beam was ok, but the Optisolis hotspot had a strange off-centered blob. So I put some Dc-fix #3 between the lens and reflector and wow, what an improvement!
The beam turned out great and the tint is slightly rosy.
