I was spoiled by a 25w halogen for a few years. but lack of reliability (burned bulbs, batteries), weight, complexity, got to me finally.
the dual setup works great. Not quite as much light as the 25w Halogen but close. PLENTY of light for as fast as I can go....
Oncoming cars think I'm a motorcycle
i like the fact i can turn them down to Hi and run for almost 5 hrs at 240lumens!
I like so far.
