I have several of the streamlight Stylus, but they are just a bright LED and really don't light much up. I'm much happier with the microstream for just a bit more cost. Much better focused light output than just the pen lights.

(ps, I'll be selling my set of streamlight stylus lights soon, once they return from warranty repair)

Too many great options for lights now to deal with the cheap stuff I've bought over the years. I'm going to replace it all with modern LED lights. 20 lumens and up.
