I just did another test run and I'm having issues with how to dim these. My controller has 5 channels, but for some reason when I run these through the controller, one light works great, but when I add the second one, they lose brightness.
The power supply is not the issue as it has the ability to do 20 amps, but it must be a channel limitation of the controller.
I'll have to go back to the drawing board with these "pucks". I really want to stay with the current power supply and controller I have, as they work great. I'll keep you guys updated.
