If you are looking to conserve energy, than 2-3 ultrabright white LEDS, capable of 15,000mCD on just 20mA, are the way to go.
Hi CrossRoads
Are you talking about something like this :
So I don't waste the energy on the 7805, but instead use that energy on 3 of these connected in series, with a 56 ohm resistor ( 0.5 W ) onto the 12vDC supply ?
I assume that if I need to tone them down, I can just increase the resistor value ?
