Here is what I'm thinking about.
SSC P7 C-Bin LED $15.20
http://www.dealextreme.com/details.dx/sku.12721
Voltage input: 2.8V - 6V
Output current: 140mA on low, 1,000mA on med, and 2,800mA on high
$6.75

i'm going to make a battery pack to clip on my belt
Parallel 4 pcs Tenergy Li-Ion 18650 3.7V 2600 mAh Rechargeable Batteries with Internal PCB
$29.00
I want to have at least two hours on high and lite weight.

I have several different old lights that I'm thinking about using for the head.
Does this sound like a reasonable build so far?
