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 low output level, you will be able to access higher brightness levels again.

Turbo and high modes may be unavailable or limited as the battery gets low on charge.

Summary: An output of 2000 lumens and runtime of 5 hours (for example) 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.

Exact specifications can vary between torches, batteries, age and environments.
