I've got the Cygolite Hotshot Pro 200 .... amazing light with very long battery life. Extremely bright but you can set the brightness. Also very good for daytime cycling
Oh... I bought the 100, because I got the impression the 150-200 were too bright and annoying for people. I didn't realize you could adjust the brightness, or I would have got the 200 because they are essentially the same price.
