Cool site. I might not have even known about it but it looks like
somebody took the work out of my do it yourself project. Now I have one
more bookmark.

Many "good" machinists are good at other stuff too. A good friend of
mine is a maintenance mechanic and is into electronics on the side.

That may be due to the cell phone phenomena, but can work out for a
small bicycle, too. My Cateye may get Lithiumed.
Thanks, Chalo, that is good input.

Yeah, I was wondering about that...the optics make it so that, what,
oncoming traffic isn't blinded? Better peripheral vision??

For $500 more than an Arc Ultra HID, it only lasts 4.5 hrs., too!
Still, I applaud all development in this area...I'm surprised it's
taken this long!

Thanks. Lots of info in the links. Perhaps your blackholed reply will
show up eventually. I've got a NiteRider HID that I like quite a bit.
The bulb replacement is annoys the wallet though. I recently installed
a couple of B&M bottles and Dymotecs on my kid's bikes and was really
impressed with the setup. Now I want to build something...

That's what I was thinking. For $500, if I needed that bright a light
to begin with, I'd tilt the "cheap" one down.

I guess you only need two batteries to get you through an audax night...
