A compact, rechargeable handheld flashlight combining a focused spotlight and a wide floodlight in one pocket-sized package, with a magnetic base and dual-color red/blue warning output.
The LI-S3 is a compact, rechargeable handheld light combining a focused spotlight and a wide floodlight in one pocket-sized unit, with a magnetic base for hands-free attachment and dual-color red/blue warning output for hazard marking. It's the unit built to go wherever a person goes, rather than a fixed or mast-mounted light for an area.
Two independently switchable light sources: a spotlight (3W max, 400lm max, 160m lighting distance) and a floodlight (6W max, 500lm max). Modes include High Output, Low Output, Flash, and SOS, plus floodlight-specific modes: standard, stepless dimming, yellow, red/blue, and red+blue flash. A memory mode recalls the last-used setting, and a power indicator shows remaining charge.
Built-in 3.7V 2000mAh rechargeable battery, charged via a built-in port. Can also be used as an emergency power source for other small devices.
Spotlight: 5 hours max setting, 50 hours lowest setting. Floodlight: 4–60 hours depending on mode and brightness.
2-hour charge time via the built-in charging port.
190g, 200 x 41.5 x 39mm. A magnetic adsorption base allows hands-free attachment to any iron or metal surface, and the unit is small enough to clip onto a belt or vest.
IP66 rated per IEC 60529 — fully dust-tight and protected against powerful water jets — with an anti-impact housing.
At 190g, this is the most portable unit in the range — carried on the person rather than set up on-site, ready the moment it's needed.

The LI-S3's compact size and magnetic mount make it the unit crews actually carry on them.

| Factor | LI-S3 | Standard Single-Mode Torch |
|---|---|---|
| Performance | Dual spotlight/floodlight, multiple modes incl. warning | Usually one fixed beam type, no warning modes |
| Power source | Built-in rechargeable battery | Often disposable batteries |
| Fuel requirement | None | None (battery-powered), but ongoing battery purchases if disposable |
| Noise | Silent | Silent |
| Emissions | None | None |
| Deployment | Magnetic hands-free mount | Usually held, no mounting option |
| Maintenance | Recharge via built-in port | Periodic battery replacement |
| Operating cost | Electricity only | Recurring disposable battery cost |
Comparison reflects general characteristics of a standard single-mode handheld torch as an equipment category, not a specific competitor product.
Battery operation means no emissions and silent use. The magnetic hands-free mount frees both hands for the actual task rather than holding a light throughout, and the red/blue warning modes give roadside and hazard-marking use a dedicated, distinct-from-white-light visibility signal. IP66-rated, anti-impact housing holds up to field handling and weather exposure. See our guide to IP ratings and industrial lighting standards for what IP66 covers.
Spotlight, floodlight, and red/blue warning modes for hazard marking.
A magnetic base for hands-free use on any iron or metal surface.
IP66, and just 190 grams.
Up to 50–60 hours on its lowest setting, with a 2-hour charge time.
