my lbs is doing a light demo next week- they've got some great pricing on
lights and I'm trying to figure out which way to go and have narrowed it down to a couple of
different lights. one is a 400 lumens LED the other is a 900 lumens HID. the primary use
is going to be for commuting- half of my commute i rail trail (very dark) the other is city
which do you think is more durable? which is a better value since both are basically the same price?
