I am trying to properly wire and then dim Cree LED tri-pods (3 LEDs on a disk).
The spec sheet appears to read that the way to connect 2 * tri-LED pods (6 individual LEDs in total) would be in series, incremented at 2.6v per pod (maybe LED). It is not clear about the pods at all.
Bench top test result only produce any light at all above 4v per tri-LED pod, with optimum at 7.8-10v in 'parallel' for two pods LED info
Also, you would think that dimming these LEDs would be via PWM but my benchtop potentiometer demonstrates that lowering voltage is the way you dimm these units.
1) Can someone explain these LEDs pods to me, their optimum voltage and proper dimming? I think my benchtop results tell the story, but I am very unsure.
2) With 7.8v being the calculated max, how bad is it to run them at 9v? There is a difference. I am sure there is some resistance in this circuit I am not factoring in.
