[3.4 grape of wrath]

It's time to retire my flashlight headlamp which got me through super storm sandy when we lost power for a week and I was able to work on my car without missing a beat. I'm looking for a led headlamp to work on my car. I didn't realize there were so many options. I'm looking for a light weight, rechargeable, ratcheting and cheap unit. The brightness is where I need help, not sure what lumen power I need.
