“These are amazingly bright - and they work exactly like regular NeoPixels. It’s quite hard to power them - I used LM7805 regulators, which get quite hot (6V - 33’C; 7.5V - 50’C), and if you do not have a regulated supply, then I noticed that the LED’s brightness changes a lot with small voltage changes, and can pull down the voltage a lot for other components. The warm white is good, and brighter than the other channels as well. Just one word of warning though: the lights are so bright that even one channel at 3/4 brightness was hard to look at.”
