I'd read positive things about this light for a while, but it's not carried by my LBS or Nashbar/Performance, so I had a hard time finding one. Well, one came up on eBay for a good price so I bought it. I'm a light junkie. I thought I had the hot ticket with two Planet Bike Superflash lights on the rear(one seatbag, one helmet). Wrong. The BLT is a LOT brighter than the Superflash. It's so bright, in fact, that I don't think I'll run it on flash mode. It will be too distracting. This one gets run on constant mode, with the PBs on flash. Wow. If the BLT is this bright, I can't imagine what a DiNotte is like. It must be like staring at the sun.
