BTL50—New-Gen Digital Zoom Flashlight,As Bright As You Need

Over the past two years, HT70 and GR36 have earned strong support from our backers, motivating us to keep improving our designs. We’re excited to introduce our latest upgrade — the BTL50 Electronic Zoom Flashlight.

Compact and easy to operate with one hand, BTL50 delivers a significant performance leap over conventional zoom flashlights. With up to 3000 lumens, a beam distance of 916 meters, and a high-performance LED rated for 50,000 hours, it combines powerful output, long-range precision, and long-term reliability in a balanced, hand-held design.

Unlike traditional mechanical zoom mechanisms,BTL50 features an electronic focus system.With a long press of the power button, you can precisely switch between a floodlight and a spotlight — all with one hand. No changing lenses, no mechanical wear, just smooth and accurate beam control.

With BTL50, light doesn’t rely on guesswork. It responds exactly as you intend.

BTL50 delivers a maximum output of up to 3000 lumens with a beam distance reaching 916 meters.

LC Diffractive Electro-Optic LensPlanar Diffractive Optical System

Unlike traditional focusing flashlights that require adjusting the distance between two lenses to change the projection plane of the emitted light, this system significantly reduces the thickness of the optical setup. It eliminates the need for motorized mechanisms or manual operation, enabling instant switching of the emitted light’s projection area through simple circuit control. Additionally, it greatly improves the light source efficiency.

BTL50 is designed for intuitive, one-hand operation, even in the dark. 

Electronic Focus Control

Easily switch between spotlight and floodlight with a one-handed rear dial, featuring four adjustable levels for precise lighting control.

Brightness Levels

When the light is on, press and hold the power button to cycle through 15/250/550/1000 lumens. Release to lock in your desired brightness.

Turbo & Strobe 
Double-press the tail switch at any time to activate Turbo mode (3000 lumens). Double-press again to enter Strobe. A single press exits these modes.

Smart Features

BTL50 features smart built-in protections, including mode memory that automatically restores your last-used brightness level, intelligent thermal control that reduces output when the body temperature reaches safe limits, a low-battery warning indicator that alerts you when power is running low, and a lockout mode activated by a triple-click to prevent accidental activation during transport.

With a built-in 3000mAh high-capacity, high-drain 18650 battery and USB Type-C fast charging, BTL50 can be recharged anytime using a power bank or other external power sources — keeping your light ready wherever you go. 

No matter where you are, your lighting device will always be ready when you need it.

Built with an aerospace-grade hard aluminum alloy body, featuring 1-meter impact resistance and an IP56 waterproof rating, it performs reliably even in harsh outdoor environments.

IP56 Rating

IP56 waterproof rating, rain, dust, and demanding environments are all part of the design brief.

The BTL50 is equipped with one latest-generation professional long-throw LED imported from the United States, specifically designed for high-intensity, long-distance illumination. It delivers a maximum lifespan of up to 50,000 hours.

Compactly designed for everyday carry, measuring just 4.33 × 1.38 × 1.52 inches and weighing only 8.47 oz. Easy to carry, comfortable to hold, and always ready when you need it.

Equipped with a durable lanyard that helps prevent accidental drops and allows you to conveniently attach it to your bag for easy access on the go.

Available in Black, Gray, Gold and Blue, BTL50 lets you choose a finish that fits your gear and your everyday carry — the same performance, tailored to your personal style.

BTL50 is estimated to begin shipping in June 2026. Shipping costs will be collected after the campaign ends through PledgeBox, allowing us to calculate accurate rates for your location. Please note that import duties, taxes, and customs fees are not included in the shipping cost and are the responsibility of the backer.
