Compact keychain light for everyday carry

The Olight LT-Mini01-Black is a 4.5-gram aluminum flashlight built for pockets and key rings. Its 3535 LED runs on three LR41 button cells and offers a simple rotating switch. IPX-6 water resistance and 1.5-metre impact resistance suit daily urban use and light outdoor tasks. The body measures 25 millimetres long and 11.5 millimetres in diameter.

Replaces a phone torch for short bursts

The light is brighter than a smartphone LED and covers close-range needs such as finding a keyhole, reading a menu or walking a dim hallway. Battery capacity limits sustained high output, so it is not intended for extended high-brightness runs or long-distance illumination. After a few minutes at full power it drops to a low mode that can last 40 to 50 hours. Users needing all-night brightness or throw distance should look elsewhere.

Button-cell capacity and low-mode endurance

Three included LR41 cells power the emitter for brief high-output tasks and then sustain a faint glow for up to 50 hours. The LED is rated for 50000 hours of service life. Spare O-rings are supplied to maintain the waterproof seal. The tiny form factor means no room for larger cells or rechargeable circuitry, so runtime at full brightness remains short.

Questions about this item

What are the exact dimensions of the LT-Mini01-Black so I know it fits my key ring?

The body measures 25 mm long by 11.5 mm in diameter and weighs 4.5 grams, making it roughly half the size of a finger.

How do I install the three LR41 button cells without damaging the O-rings?

Unscrew the tail cap, stack all three cells positive-side forward, then tighten the cap just until the two spare O-rings seat — over-tightening crushes the seals.

When will the 3535 LED or the LR41 cells need replacement?

The LED is rated for 50000 hours; the included alkaline cells typically last 40 to 50 hours on low mode after the initial high-output minutes.
