Shooting Reviews is finally up and running after several platform changes. My first article, on one of my favorite subjects, the personal light, has been posted.
In this age of bright and compact lights, I have often suggested carrying 2 or 3 lights. It's just too easy to carry a Photon microlight on a keychain, and I have frequently also carried a lower-powered task light and a higher-powered tactical/emergency one.
Redundancy is a good thing, when it comes to personal protective devices, and lights certainly fall into the category of frequently-used PPD. I still suggest carrying the Photon, or a similar small backup light, but I think you'll agree after reading the review that the ElZetta M60 is the most light you'll need for the rest of your life. It's not the most expensive light I've ever owned, but it's certainly the toughest, and I think the most useful.
