I just wish all these "el cheapo" outfits could just cross-over the line and come up with a 2.5 or three-watt "cheapy" light.

I've bought, tried and measured five head lamps, three energizer styles, one unknown, and one Lenser.

The one thing I know for sure - you can't do it right with only one-watt of power. It's best to have at least 2 watts, and three watts makes a light usable for primary lighting. I can't believe I once rode around at night with two 40 lumen cat-eyes thinking I could actually see well because i aimed one spot a twenty yards up the road.
