Which is better:

Cateye HL-EL 530 headlight or Task Force 3-watt 225285 flashlight?

I sometimes bike on country roads at night, always under 12 mph. Either I lost or someone stole my Cateye 530. I was pretty happy with it. It provided sufficient light when combined with a helmet-mounted headlamp.

The Task Force seems quite heavy. Anyone know how long the C batteries will last?

Which one is brighter? Widest spill? Etc.
