We’ve had a few users asking if these multichip LEDs would work on the MakersLED Heatsink.
We decided to grab a 40mm and a 20mm wide multichip off eBay and put them to the test. The larger multi-chip LEDs require high forward voltages, so of course we decided to our new MakersDRIVER which has up to a 45V forward voltage.
As you can see in the pictures, our patent pending LED star mounting t-slots had no problem mounting these big guys down to the heatsink. We did put a dab of thermal grease down under the LED to make sure it was completely in contact with the heatsink.
We turned the LEDs waaaaay down with the MakersDRIVER to take these pics.
