Its a pretty cool industry. I have worked on similar tech signs and the advancements on these new billboards is awesome. I currently service a sign right now but of course a much much smaller scale. I also live right next to YESCO now Prismview (Samsung) that literally built most of Las vegas Signs and Digital billboards. Prismview is A competitor to Daktronics but still a major player in that market. Every once in a while I get access to their excess LED's when they expire them. What is insane is the price of these Buggers. A YESCO sign with a dual 6ft x 6ft panel (front and back) is well over $65k I could only imagine what these massive signs would run. easily in the 100's thousand to millions I would imagine.

I ran across this guy yesterday: https://www.youtube.com/watch?v=e-rdgB_19Fg

I gave up trying to calculate the cost, etc. My math must not be working this morning, but I came up with 1000A worth of 5v at full power. That doesn't seem right. (35 rolls of 96 led/roll was my guess)

35x96x0.060A =~200A still a lot!

My bad though, 96 led/meter on 5 meter rolls=1000A. I'm only assuming 96 led/m, based on the videos. There's no way in hell, they must be limiting brightness to 25%. That'd be some Christmas Vacation level stuff firing up that many pixels at full volume.

I mean, this is about 200 ish 2812s on 100%

While in Las Vegas I got to see the light show "Lake of Dreams" at the Wynn hotel.

Very cool - underwater 4000 leds.

Heres a photo during the day I took.
