I remember the Taz 1000 making a little noise when it was on and I just loved it...it was ridiculously powerful at the time. Now I see it as a better practicality at lower settings since you can run a higher low setting for a lot longer then smaller lights. That is why I am considering a Cateye 6000 just to run it at low settings and not recharge it for a long time. 500 lumens for 12 hours sounds pretty cool and if I ever need to burn through stuff I can go up to 6000. However it is an expensive light and would be a rather silly purchase just to max out at 1000.

Granted I am also super interested in dynamo stuff so I might not be buying USB lights for a while the only bike I would ride at night that I wouldn't put a dynamo on is my Ti road bike at this point.
