Last week I bought a Streamlight Stylus Pro (90 lumens), which was an impulse buy (I do like the form factor of AAA pen lights). I had bought one of these when it was first made available to the public a few years ago (I think it had 47 lumens). I sold it to a co-worker when I bought a Pelican 1920, who promptly thrashed it. The switch is a little hard to push for constant "on," but is supposed to lighten up with use. We'll see.
The week before, I bought a Fenix PD25 and 2 Photon 2s at a gun show in Orange County. The PD25 will be an EDC light. One Photon light is currently on one of my SAKs, and the other one I gave to a female friend. I've been using Photon lights for years - never a problem.
