I would probably be cheaper and easier to use ordinary LEDs and run them
from 5V.
It's not a single led, it's a 30 led package MR16, which is a good area
light, in a nice neat package.
Works well, 10 hours off 10xnimh AA, just looking to run off 4 AA
Struck me too that AFIK most LEDs operate from 1.5 to 3.0 volts?petrus bitbyter said:It helps if you tell us what kind and type of 12V LED you're talking
about.
I never saw 12V LEDs so your 12V type is an appliance of some kind. May be
electronic, may be some LEDs in series or only a LED with a simple series
resistor. An optimum solution depends on this information.

drop-in replacements for automotive/truck lamps in
tail-lights, etc.

So the 12 volt package must either have a) A dropping resistor which wastes
some 8 or 9 volts,
or b) LEDs in series (unlikely?).
Why unlikely ?? Works for us !
