I just got some solar garden lights, and they seem to power an LED (colour changing) from a single 1.2V NiMH. Can you get LEDs with a forward voltage that low, or does it have a booster in it? All I can see is a microchip (one of those black blobs so I don't know what's in it), a capacitor, and a resistor.
