The Imalent BTL50 is a digital zoom torch that offers electronic beam adjustment, allowing instant switching between flood and spot illumination. It delivers a powerful maximum light output of 3000 lumens and a beam distance of 705 metres. Powered by a built-in 3000mAh 18650 lithium-ion battery, the BTL50 provides a maximum runtime of 89 hours and supports USB Type-C fast charging. Its innovative electronic focus system, featuring an LC Diffractive Electro-Optic Lens, ensures smooth and precise beam control. Equipped with a cool white LED, it achieves a peak beam intensity of 124270 candela, offering stepless brightness adjustment, Turbo, and Strobe modes. The torch is rated IP56 for ingress protection and has 0.5 metre impact resistance, with smart protections including intelligent thermal control, a low-battery warning, and a lockout mode for safer transport.

Performance and Runtime Disclaimer
How to read the data: The outputs provided above are maximum outputs for each mode, and the runtimes provided are the time it takes to drop to 10% of the initial output. This is in line with the International Flashlight Testing Standard ANSI FL1.
Any visual representations (graphs) of the data are approximate only.

The actual output of the torch/headlamp is controlled by an in-built temperature regulation system. As the torch/headlamp heats up, the brightness will drop to prevent overheating. The Turbo modes of torches/headlamps usually drop down significantly after anything from 15 seconds to 2 minutes. High modes often also experience a drop down over time. Medium and Low modes, however, can be constant for very close to the length of time specified. As the torch/headlamp cools down, either from being turned off or from being used on a lower output level, you will be able to access higher brightness levels again.
Example: An output of 2000 lumens and runtime of 5 hours does not mean 2000 lumens for 5 hours — it means it starts at 2000 lumens and drops below 200 lumens after 5 hours of continuous use.
Turbo and high modes may be unavailable or limited as the battery gets low on charge.
Exact specifications can vary between torches, batteries, age and environments.
