I have a 1W Blaze and a front Flea. The Flea is bright,but does not have the throw of the Blaze. On the ground right in front of you it looks brighter because the 4 LED's in a row make a wider,more 'filled in' spot,but shine them out a ways and you'll see farther with the Blaze. Basically,the Blaze makes a better headlight,the Flea makes a better blinky. I do like the ease of mounting with the Flea. I put it on the front of one of my helmets with one of those PB rear blinkys with the pivoting helmet mount on the rear,so when I got bar hopping I don't have to pull lights off the bike when locking up.

One thing I don't like about the Flea is that when the battery drains it goes right from full bright to dim without warning. I wish it would gradually dim the way most lights do,so you'd notice it and know it's time to recharge. Twice I've been riding and had it crap out.
