That is why Hella does not rate it's lamps in Candlepower. There is no industry
standard on how to do it.

The way you figure the Amperage draw of a light is to take the Wattage and
divide it by the Voltage. For instance, if you have a 55W Fog Lamp on your
truck, it would draw 4.58 Amps. Of course, this is *assuming* that your charging
system runs at a constant and exact 12V, and most of us realize that it
fluctuates, usually hovering just over 13 or 14V.
