Doug's light is a decent compromise. Nothing wrong with it.
You know what I like best about the Arc, though? It's (almost) idiot proof. I mean, it only has one function... it's either on or off. Changing the battery is so simple my parents can do it. There are no precautions you have to give someone before they carry it. Sit on it? Well I wouldn't (owww!) but you can and it won't hurt it. Get it wet? Sure...go ahead. Drop it? No problem. I mean, you just can't hurt an Arc in any situation likely to come up. Mostly, you just hand someone an Arc and say "Twist it on, twist it off, change the battery when it gets dim. Have fun.".
