Pros: Bulb Durability, Battery Life, Durability, Brightness
It turned on in my pocket and ran down the batteries.
I have owned Photon micro lights before, and they are all very good quality, especially the ones with high output. I made a mistake by attaching this product to my key chain. In carrying the chain in my pocket, it depressed the on button, and it ran --likely for a long time-- until it was dead. This was a self inflicted wound, not a product fault. Just be aware. Perhaps Photon, who has shown excellent product development changes, might see this message and think about how to keychain-carry enable a microlight. I always liked the short lanyard clip, and love the hat clip feature. I am not sure how I would use the longer lanyard as it is to small to fit around my fat head. Fortunately, Photon has made it easier to replace the battery cells. You no longer have to use a micro phillips screwdriver and "perform device surgery" to re-cell the light.
