Hi folks ~ another question if you don't mind...
Rather than commit my mother's bedside light to a landfill, I want to see if I can hack it to power a nice bright LED strip (
this one) which runs @ 12v DC.
My tranny puts out 13.7v AC and I have one of those square-block rectifiers for DC but so far nothing else.
The LED product info does not give the LED config (series/parallel) or the forward voltage and I'm stuck on how best to drop the volts to 12v DC. I realize a cheap switch-mode PS would be the most efficient but I hate to add to the landfill and prefer to work with what I've got.
Is an LM317 the way to go, or will a simple series dropping resistor do?
This LED strip seems more complicated than a simple LED and I don't know how to calculate the appropriate resistance/wattage for the array.
Thanks for your input!
