Lead vs Aluminum

I would like to know the difference of consumption of amperes, for anodizing tank with lead cathodes and an anodizing tank with aluminum cathodes. I'm using 100 amp per square meter of aluminum and 20 minutes of time to form 6 microns with aluminum cathodes; how many amps and what time do I need to form 6 microns with lead cathodes.

Because of Faraday's Law, the required amperage to anodize should be identical regardless of cathode material. However, the required voltage is said to be lower with aluminum cathodes, meaning power savings. I can't personally put a figure on the savings, but some of our other readers hopefully can.
