Is there a preliminary setting to set the LED amperage from the power supply? It's on a Kinoton projector with analog and digital.

All of the way down!

That is where one starts on both. Normally, the analog can stay there a LONG time. The digital probably will need to be turned up. Ideal tracking on digital will be attained with the Video response at 4Vp-p (set via OScope though the CP650 with reasonably current firmware can also read out the voltage). Use a scope though since you also want to get the most uniform response.
