I set up a 3W violet LED to run on the T680 (above the Kohler unit) and used one of those motor controllers this time. It seems to work fine. I just have to set the input voltage to 5V then a very slight turn of the pot from minimum and the LED just starts to glow. Probably a slightly higher input voltage would allow some overdrive, if needed. So thanks for your idea, Greg - a very cheap and easy LED driver/dimmerGreg Howald wrote: ↑Thu May 19, 2022 10:10 pmYour equipment if far better than mine. I have a power block, a pvm, and a lamp.
