bike light

[bikin' Ed]

I've got almost everything I need to build myself a new set of bike lights. I have decided to go with HID since it seems to be the most light for the least work and money.

Here's my question: All things being equal (lens, reflector, etc.), will a 12v, 10w bulb, be about twice as bright as a 6v, 10w? It seems that my costs and labor for either is about the same, so which is the better value?

Any documentation/specs on candlepower/lumens for either?

I'm going to hazard to guess that they should be about the same, If the Wattage rating is the same 10W. You'll just draw more current on the 6V then the 12V.
