Looks like the v1, v2, v100, v110W, x10 and others are being discontinued, the nubm44 may no longer be produced.....I suspect most will be switching to the cluster arrays.

I've actually discovered another source for them... I'm calling them a "V3" for lack of a better term. They don't require heat extraction, just unsoldering from PCB. There is some thermal paste on them which wipes off easily. These diodes seem to have better and more uniform beams since I believe there is some warping to the die from the extreme heat needed to extract them from the NUBM44 blocks. There seems to be a decent supply of them for now which is why I haven't had to increase my prices.

Oh yea, rows 1 and 3 are the thermal paste " V3 " and rows 2 and 4 are the indium heat bonded/extracted.......so I suppose they do the same 7.5 - 7.7w from a cold start in a room temp. sink ?
