"Great light and I can’t believe how Streamlight has progressed. I’ve carried a ProTac 2x 500 lumen for ages. Amazing that this is the same output and similar runtime in a comparatively tiny form factor. It’s quick and easy to use, super bright, and is a perfect balance of design and output for serious use while being small enough to be convenient every day. Rechargeability is also a big plus."

I have had this flashlight for almost 6 years now. It’s never failed me. I dropped it in the woods at a zoo. I work at, and it was lost for a month, found, and worked perfectly. It also dropped out of my pocket and went in the water with over 30 big alligators. Stayed in the sand at the bottom of that pool for about three weeks before I drained the pool, moved some alligators, and found it mostly buried in the sand. Picked it up, and it worked perfectly still. I cannot recommend this flashlight enough! (The reflective and glow-in-the-dark tape I added to the flashlight is due to the nature of my job and makes it easier to find if I drop it in the dark and it’s not on.)robert g

I own several flashlights, and this one is close to if not my favorite. I use it for work (septic systems) and it will light up a tank or down a deep cleanout really well! The hat clip is also really useful. The battery life leaves some to be desired, but other than that it is great! It will probably run for 30min+ on high.What Customers Talk About
