I'm risking making myself seem foolish here but I just don't know so here goes. I have a camcorder with a 12v DC output that's intended use is an on-camera light fixture. I've traditionally used a 20w incandescent light. In an effort to increase battery life I got an LED fixture that is powered by 2 AA batteries rated for 3 to 4.5V.
Now - I don't want to be dealing with AA batteries all the time and wish to power it from the cameras output. I'm guessing I need to reduce the voltage somehow or I'll blow my LED lamp.
Is it just a matter of splicing a resistor in on the positive wire? If so what kind exactly?
I need to keep it light and compact so a DC-DC converter type unit won't really work.
Can anyone advise me in simple terms?
