The Flat Profile EDC

LIGHT WITHOUT
THE BULK.

Most flashlights are cylinders that fight your pocket.
The S3 is a flat, matte-black slab that disappears until you need it.

Watch Demo

Title

You peel back the seal.
The box slides open.

You lift the S3 and notice the weight first—solid, but not heavy. The aluminum is cool to the touch, with a fine-grit matte finish that feels like a precision instrument.

You slide it into your pocket. It doesn't bulge. It doesn't roll. It just sits there, flat against your leg, ready for the day.

Then, you click the button. The 1200-lumen beam hits the wall, and you realize you'll never use your phone's flashlight again.

Three Tools. One Pocket.

The S3 isn't just a flashlight. It's a multi-spectral utility device designed for the unexpected.

1200 Lumen White

Walking the dog at 11 PM? Press and hold the switch for 0.5 seconds to turn the neighborhood park into high noon. The beam reaches 150 meters, lighting up the path before you even step on it.

365nm UV Light

At a hotel? Check the sheets. Buying a vintage watch? Verify the lume. The UV light reveals what the naked eye misses, from pet stains to counterfeit bills.

Red Laser Pointer

Pointing out a leak in a dark attic or leading a presentation in a bright room. The laser is sharp, precise, and always at your fingertips.

It sticks where
you need it.

You're under the sink, wrestling with a pipe. You don't have a third hand to hold a light. You snap the S3 to the metal cabinet hinge. It stays.

You're working on a server rack. You clip the S3 to your hat brim. The flat profile means it doesn't weigh your head down or bounce while you move.

It's not just about brightness; it's about being where you need it, when you need it.

Before the S3

Fumbling with a phone light that barely reaches your feet.

A bulky flashlight that rolls off the table every time you set it down.

Checking for stains with a separate, clunky UV wand.

With the S3

Confidence. You know you can light up a whole alleyway in a second.

Efficiency. One tool for lighting, inspecting, and pointing.

Comfort. You forget it's in your pocket until the lights go out.

​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 !!

Bought one to see it’s durability.

Use it as a secondary flashlight for work. Would love to buy one for my personal car.
