1,200 watts of throbbing LED power. These are going to be used in a strobe unit to freeze falling water drops, or depending on the frequency, to make them (seem to) flow in reverse. While 1.2KW sounds impressive, and it is, note that these will have a very low duty cycle. In other words, 99.9% of the time they’ll be off, so the apparent brightness will be pretty reasonable, and no heatsinks will be required. The very brief ‘on’ time is required to solidly freeze the motion of the drops, kind of like a fast shutter speed on your camera.

An excellent example of the fine motor control that 6 month old babies are capable of. I think she has more sweet potato on her feet than in her stomach.

Lake Mead.  Colorado River, Hoover Dam, border of Nevada and Arizona. About 45 minutes outside of Las Vegas.  Largest man made reservoir in the US. Currently 125 feet below the top of the dam. In 1998, the level was 7 feet below the top of the dam, which for the record is more than a bit too high. A 14 year drought has put that worry off for a while.

Being productive in Las Vegas. It’s beautiful, but the opulence seems to foreshadow something very dire. Don’t get me wrong, I’m enjoying this, but I’ll take a spot in the forest overlooking the ocean any day.
