ordered a couple of these:

Note - the 100W chip and the 70W chip are exactly the same -- no sense in ordering 100W version.
I was hoping these would compare favorably to a vero 18 (I have a gen6) when run @ 10W or less and so far, it appears to do pretty well in my simple lux meter tests. I tested the chinese cob against a vero18 4000K 80CRI (gen6) at 270ma. the Chinese cob was drawing 27.5V and the Vero 27.0V. the both scored really similar #s on my cheap lux meter at equal distances. I don't have any good ways to do precise measurements so maybe I'll ship one over to @CobKits to throw in the sphere just for fun If it was to hold up over time, it's a decent value at $2.19
