The Cateye looks pretty neat. That's a pretty impressive light output for 3 LEDs, although I suspect the focusing lens helps that a lot. Mine doesn't have any focusing apart from what's inherent in the LEDs.

I've been using my light for a few weeks now. I'm very pleased with it so far. I've got plans to attach a focusing mirror which should reduce the amount of light spilling out the sides (and into my eyes) and direct it more where I want it. It's bright enough on the road now, but this will just make it better.

I'm not certain of the exact run time on a charge, but I estimate it at about 4-5 hours, but it runs almost indefinitely in flashing mode. Even if you get no light whatsoever out of it in constant mode, the flasher still works as well as when it's fully charged. An unexpected bonus. I could make up a bettery with 6 NiMh 'D' cells if I want (at $24 a pop it's not the cheapest option) which will more than treble the run time (and probably the weight).

I'm impressed with the runtime the Cateye claims, although I'd have to see the actual working unit to see exactly how impressive it is. Mine, despite the extra batteries runs less time, probably because I'm using 10 rather than 3 bulbs (although the rated total output of the ones I'm using is 60000mcd), and I think I'm overdriving them a bit too ie. I'm pushing more than the rated 20mA through each one.

I've updated my webpage on it recently. See this page . In fact if anyone's interested, I've given my whole site a bit of a facelift. Check it out .-damn, I just looked at it again - looks like I need to do some formatting on the front page
