I recently saw this on Topeak's new products PDF, and am thinking about getting one. It would replace a Cateye HL-EL500 which broke. The Cateye was a 1 watt led and was a decent battery headlight. I'm intrigued by this new Topeak model because it's a 3 watt led. Bikesomewhere has it for under $75. Has anyone tried out this light?
