    Can anyone tell me how bright an LED lamp consisting of 12 leds,
    making a 24v units, would be compared with a 24v 20W halogen capsule
    Also, can anyone refresh my memory of the candelas to lumens

    12 leds at 2 volts apiece and 20 milliamps is only 0.48 watts.
    The 20 watt halogen lamp will be much brighter, probably 40 times
    brighter or more since incandescent lamps are more efficient
    than leds.
