The MAXTOCH L2KSD is a compact, extreme-distance LEP spotlight built for users who need to see far beyond the reach of conventional LED flashlights.

Powered by a single 21700 battery, the L2KSD produces up to 900 lumens and delivers an impressive maximum beam distance of 3,400 meters (2.1 miles). Its highly concentrated LEP beam minimizes unnecessary spill and directs the light toward distant targets, making it ideal for long-range observation, search applications, large properties, open terrain, and outdoor exploration.

As the shorter version of the L2KD, the L2KSD maintains serious long-range performance while reducing overall body length to just 181 mm. The result is a specialized long-distance flashlight that is considerably easier to carry and handle.

Diamond Phosphor LEP Technology

The L2KSD uses an advanced Laser Excited Phosphor (LEP) light source featuring MAXTOCH's diamond-based phosphor technology.

Instead of spreading thousands of lumens across a wide area like a conventional LED flashlight, the LEP system concentrates its output into an exceptionally intense and narrow beam.

Combined with a precision aspheric lens, this allows the L2KSD to achieve extraordinary throw from only 900 lumens.

The result is a clean, focused beam designed for one primary purpose:

putting usable light extremely far downrange.

Extreme 3400-Meter Beam Distance

The standout feature of the L2KSD is its maximum rated 3,400-meter beam distance.

That's approximately:

3.4 km / 2.1 miles

This exceptional throw makes the L2KSD suitable for situations where identifying or illuminating distant objects is much more important than lighting the entire foreground.

It is particularly useful for:

• Long-distance outdoor observation
• Search and inspection
• Large-property monitoring
• Open fields and remote terrain
• Mountain and wilderness exploration
• Long-range signaling and spotting
• Flashlight enthusiasts looking for extreme throw

Unlike a high-output floodlight, the L2KSD concentrates its energy into a narrow hotspot with limited surrounding spill.

900 Lumens – Designed for Intensity, Not Flood

With LEP flashlights, lumen output tells only part of the story.

The L2KSD produces a maximum output of 900 lumens, but those lumens are concentrated into a much smaller area than they would be with a typical LED flashlight.

This produces extremely high beam intensity and allows the light to travel dramatically farther.

If you need to illuminate an entire campsite or trail at close range, a high-lumen LED flashlight may be the better tool.

If you need to illuminate something hundreds or even thousands of meters away, the L2KSD is designed specifically for that job.

Compact Single-21700 Configuration

One of the biggest advantages of the L2KSD is its relatively compact size.

Instead of using a long multi-cell body, it operates on just:

1 × 21700 rechargeable Li-ion battery

Overall dimensions are approximately:

181 × 60 × 25.4 mm

with a weight of approximately:

295 g

The large 60 mm head provides the space required for its long-range optical system, while the shorter single-cell body makes the flashlight easier to carry, store and operate.

For users attracted to the performance of the L2KD but looking for something shorter and more manageable, the L2KSD offers an excellent alternative.

Precision Aspheric Lens

The L2KSD uses an aspheric surface lens engineered to control the highly concentrated LEP light source.

This optical design helps produce the characteristic LEP beam:

tight hotspot · minimal spill · exceptional distance

Rather than illuminating everything in front of you, the beam directs the majority of its useful intensity toward the target area.

This makes the L2KSD especially effective across large open spaces where conventional flashlight spill can become unnecessary or distracting.

Up to 4 Hours Runtime

Despite its compact single-cell configuration, MAXTOCH rates the L2KSD for a maximum runtime of up to 4 hours, depending on operating mode and conditions.

The removable 21700 battery format also provides additional flexibility for extended outdoor use, as spare compatible batteries can be carried when longer operating periods are required.

Three Colored Filters Included

The L2KSD comes with three colored filters, giving the highly focused LEP beam additional versatility.

Users can adapt the light for different observation and outdoor situations without needing multiple dedicated spotlights.

Simply install the appropriate filter when a different beam color is required.

L2KSD vs. Conventional LED Flashlight

The L2KSD is not intended to replace every flashlight.

It is a specialized long-range lighting tool.

Choose an LED flashlight when you need broad, comfortable illumination around you.

Choose the L2KSD when the target is far away and maximum beam concentration matters more than flood.

Specifications

Who Is the L2KSD For?

The MAXTOCH L2KSD is best suited to users who prioritize distance over flood.

Its combination of a 3,400-meter rated beam distance, compact single-21700 body and highly concentrated LEP optics makes it an excellent choice for long-range observation, outdoor search, remote-area exploration and serious flashlight enthusiasts.

It isn't designed to light up everything around you.

It's designed to put the light exactly where you need it — even when that point is kilometers away
