Anything L&M makes is excellent.

If you are serious about riding after dark, I highly recommend L&M's Arc-LiOn lamps. They are an investment but very much worth it.

I also have the Dinotte. I use it for a backup headlight. Quality-wise, it can't touch L&M. I've had to improvise by gum-banding the lamp attachment to the battery because the connection has gotten increasingly unreliable. Not a big deal but be advised. YMMV. I plan to replace this one w/the Stella, perhaps sometime in '09.
