I'm working on a homemade mod for my Demolition Man. I found a set of 12V LED angle eye rings made for going around car headlights. At 12V they draw about 600mA and are INCREDIBLY bright. Using my bench power supply and dropping the supplied voltage to 9V produces a better brightness and subsequently lower current draw.
My question is...Can I simply connect 4 diodes in series to drop the 12V from J116, J117, or J118 on the driver board to ~9V (4X0.7V=2.8V; 12V-2.8V=9.2V)?
Is there a better (and simple) way to do this?
Thanks in advance!
