Looking at the higher res picture closely it seems they’re using the same types of leds I made my LED light source from. ( http://www.ebay.com/itm/50-Pcs-1W-High-Power-Cool-White-Led-Lamp-Beads-90-100-Lm-5000K-/330722723619?pt=LH_DefaultDomain_0&hash=item4d009c4723 ) They probably ordered the same thing from ebay. :)

I made mine from 40 leds as a strip 150 mA instead of 300. They probably underdrive them about as much.

I dislike the yellow (mocked as warm-white) that most light sources produce.

Cold white is not that good either outside bathroom/kitchen.

(It only really gets blue above 6500K. 6000-6500 is sterile white)

Many will consider this too blue/cold for at least residential use.
