Absolutely love this light!!!!!
The light definitely holds a charge longer than most of the lights I have used. I use it on an hourly basis for my job as an hvac tech, in an attic, crawlspace or basement. Great product

"This thing is awesome, I’ve had mine about three month and absolutely love it. I’m in construction and carry it every day. Must have. Thank you ultrafire"

- James Gardiner

"I carry mine exactly like this one everyday. I have 6 or 7 EDC flashlights but I always reach for this one."

- Chip Bryant

"The UV light on the S3 has been super handy for me. I’ve used it at the garage to spot small leaks and check for fluids that aren’t visible under normal light, and even at the market to quickly check fruit freshness. Didn’t think I’d use that feature so often, but it’s actually saved me time more than once."

- Michael Anderson

Happy customer

Many people I work with have the expensive brand and I'm very happy paying alot less for a flashlight that's as good if not better

This flashlight is an absolute gem!

The UltraFire S3 is a true powerhouse, offering an impressive 1200 lumens in a compact, stylish design. The inclusion of UV and laser functions makes it incredibly versatile for everyday use and special tasks. I particularly appreciate the magnetic tail cap, which is a lifesaver when you need to go hands-free. With its solid build, easy USB-C charging, and excellent performance, this is my new go-to EDC light. Highly recommended !!
