Wuben H4 - 800 Lumen Rechargeable LED Headlamp
The Wuben H5 is a versatile headlamp designed for hiking, repairs, and daily tasks, delivering up to 400 lumens of light from its OSRAM P9 LED. Its innovative dual-axis rotating clamp allows for full 360ยฐ adjustment and 180ยฐ forward/backward tilt, ensuring flexible, no-dead-angle illumination. With a maximum beam distance of 73 metres and a peak beam intensity of 1338 cd, it also offers a wide 175ยฐ beam coverage. Powered by either a Wuben ABF920R rechargeable 14500 lithium-ion battery or a standard AA Ni-MH battery, it features convenient USB Type-C recharging and provides an ultra-long runtime of up to 120 hours. The H5 includes five practical lighting modes: High, Medium, Low, Moon, and SOS. Constructed from durable aluminium alloy, it has an IP68 ingress protection rating and 1.5 metres of impact resistance, complemented by a magnetic tail cap for hands-free use.
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 โ 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.
