Interesting theory. I am not sure if I got my timeline straight, because I do not remember what months the supply of Rebels decreased (in 07). Also, do you mean the decrease in supply during the months this year where the TFFC Rebels and K2s were recalled? This thing was probably built months ahead of time. In addition, we can never be sure if only RBG rebels were used in this ball, or if any whites were used (if so, then TFFC or non TFFC). That is a good quantity of emitters (32,256), but how does that compare to the monthly production from Lumileds? I heard about the 32K emitters used late last December, but I assumed that regular Luxeon K2s or Luxeon III emitters were used to save money (using older technology). Hmmm... :thinking:

They used RGB K2s in the central sections and the linear sections of the ball housed either Rb80 or Rb100 TFFC white rebels.

Good god how do you cool that many LEDs inside a ball?

With ~30 degree F ambient air, I'd think pretty easily because they could use active cooling with fans.

PS Speaking of 30 degree weather. Our oldest is away at college and had her first night below freezing. Now they're talking maybe snow on Monday. Did not like that at all .
