As my current supplier is located in Europe, communication is going slow and they don't really care about their customers. That's why I don't like big distrubuting chains! Argh I will see if I can work sth out, I'll let you guys know in case I have some useful info.

That is what i saw to the same supplier here in EU. I didn't like the fact that their reply was as if they were bored to make business with me.So i gave up with them, good luck Erasmus! I guess they told you almost the same prices with me right? At the current currency it is not worth buying from EU...

I have a chance to play with SST-50 and SST-90 a little bit. As you could guess, the beam is pretty floody, just like MC-E and P7. Using a McR-27S reflector and driving at the same 3A , SST-50 seems to have 20% more lux at 1m when compares to MC-E. But I'm not 100% sure if focus is optimized in either case, and I didn't measure overall light output.

I tried a 45mm smooth reflector that I had on hand. I couldn't see any dark hole. That's good news. Beam pattern seems to be pretty smooth as well.

SST-50 could be a drop-in replacement for some MC-E applications. I'll try to replace the MC-E from my Legion II with SSR-50, and see if it will take care of that awful cross/hole in the middle.
 
Cool, I'll wait till the low serial numbers get used up and the novelty wears off.

Edit: Just saw they are the 6500K, 70 CRI ones. I'm so done with those from any manufacturer.

where can I buy stars for sst-90?????????????????

for sst-50 we can use XR E stars but the sst -90 maybe are too big for xr e stars

XR E star : 9x8-10x9 mm

sst-50: 9x7.3 mm

sst-90 11x10 mm (maybe too big for XR E stars)

I would just solder a 3mm or so copper shim on the bottom to raise the electrical pads above the heatsink, solder wires on and attach the shim to the heatsink. It has way better thermal conductivity than a star too which is very important with a LED as big as the SST-90.

Or are the contacts on the top? I'm not sure and don't want to download the datasheet right now... if they're on the top, just epoxy it on. If they're on both sides, just use the shim but solder the wires to the top.
 
Just one note on these LEDs. As you might be able to see in these pictures the die is attached with a conductive epoxy. Also since the construction is similar to the Cree with a glass dome and silicone gel holding the dome on they will be easy to knock off. This provides a tantalizing opportunity though as it may be possible to to remove the die and mount it directly to a heatpipe.:naughty:
