In my quest for a completely silent drape runner, I ended up with a "universal" LED Floodlight Driver.
Essentially, it's a driver for the WS281x RGB LEDs commonly used in floodlights. However, this driver's range is 12V-35V, and the current can be regulated (by swappable SIP-resistors) from 240mA-1400mA.
It's been fine driving a 10W LED (12V, 350mA) and a 50W LED (25V, 650mA). So far, I've only been able to push it to 30V (that's as high as my PSU goes) to regulate a constant-current of 1000mA (I don't have a 100W RGB LED nor appropriate heatsink, so I'll need to fully test there).
Anyway, thought it was pretty neat--especially since I use several floodlights in my show.
