I speculate the 1W blinkies on the market only deliver 1W in flashing mode, if even then. If you want a high-brightness steady-burn light, the Hotshot might be your ticket to ride. I haven't checked burn time in steady mode, but if it's of particular interest I could do a runtime test.
Cygolite claims a minimum 4.5 hour runtime, with a 3 hour charging time on USB. If those numbers are accurate, that light can put out an average of about 1.2w.
Are there any tests or measurements that compare the visibility of taillights with car tail/brake lights? I don't need crazy -- I've seen bike taillights that were way too bright and I don't want to go there.
