Samsung 3535 LED, white, 512lm

Someone has tested these LED's?

They seem to have a good price, and a very competitive efficiency.

Looks interesting.
I notice that on the datasheet, the normalised flux is charcterised at aprox 60 degrees, with a degredation to aprox 92% by 100 degrees. Note that the general chars are listed at 25 degrees ambient - a useless figure without any details of heatsinking etc. One must assume that these are instananeous figures from ambient. this may make the temp v's flux graph a bit misleading perhaps?
Note tha 160 Lm at 350mA is max - bin min is 130
