We recommend the UltraFire S3 for hikers and campers who want a slim light that does more than light. Price $44.99. The partner record does not list eligibility for this product. Best for hikers, campers, and everyday carriers who want a slim pocket light with UV and a laser pointer.
A 92g flat light with white, 365nm UV, and a red laser.
We recommend the UltraFire S3 for hikers and campers who want a slim light that does more than light. UltraFire lists 1,200 lumens on the white beam with a 130 meter throw, a 365 nanometer UV mode for 50 hours, and a red laser for 25 hours, selected with a side slider so you do not cycle through modes in the dark. It is 102 millimeters long and weighs 92.1 grams with a built-in 1500mAh battery, charges over USB-C, and carries an IPX6 rating, a two-way clip, a tail magnet, and a lock mode. At $44.99 in black, midnight blue, or army green, it competes well with the EX3. The trade-offs are a built-in battery and an IPX6 rating that is not for submersion.

Who should buy the S3?
The S3 suits hikers and campers who want a flat pocket light. If you prefer a warm white beam and a rotary selector, see the EX3. For more range, see the T5 or LRS2.
White beam
The white beam has four levels: 3.5 lumens, 55 lumens, 220 lumens, and 1,200 lumens, with a 130 meter listed throw on the highest. The light remembers the last white level you used.
UV and laser
UV at 365nm runs for up to 50 hours and the red laser for up to 25 hours. UV is useful for spotting scorpions at camp or checking stains, and the laser is a pointer for presentations or trail markers.
Charging and build
The aluminum body has a hard-anodized finish, and the 1500mAh battery charges over USB-C. UltraFire lists a 50,000 hour LED lifespan.
Price and the UltraFire code
UltraFire lists the S3 at $44.99 in black, midnight blue, or army green. Our UltraFire reader code applies on the official store at checkout.
Why we like it.
Three tools, one slider
A side slider switches between white light, UV, and a red laser, and the front button turns the selected mode on or off. You always know what comes on.
Real runtime figures
UltraFire lists 152 hours on the 3.5 lumen mode, 4 hours at 220 lumens, and 122 minutes on the 1,200 lumen mode, which helps you plan a trip.
Carry and lock features
A two-way clip, a tail magnet for hands-free work, and a double-click lock mode keep it ready and prevent accidental activation in a pack.
A few things to consider.
Built-in battery
The 1500mAh cell is not user replaceable. Charge it from a power bank on multi-day trips.
IPX6 is not submersible
Treat it as rain and splash-resistant, and keep it out of lakes and streams.
Laser safety
Never point the laser or UV at eyes, people, animals, vehicles, or aircraft.
