They work great! Easy to solder by hand, good viewing angle, satisfactory brightness. The images show them being run at 18mA (green) and 17mA (red), in a fully lit room, and is enough to swamp out the camera.
They're running lukewarm at 20mA on FR4 PCB-board.
The description claims they're rated for 0.5A, but I have my doubts about that considering it also states they're 0.5W at 3-3.3V. Might refer to another product?
Very nice
