Headlamp SANDBERG Headlamp 500 Duo — LED 25–500 lm, USB rechargeable, 800 mAh, aluminium housing, IP44

The SANDBERG Headlamp 500 Duo is a compact, USB-rechargeable headband lamp with an aluminium housing and an adjustable swivel head. The LED light delivers a variable output from 25 to 500 lumens and includes a red-light option. Its 800 mAh Li‑Ion battery supports multiple brightness levels and the device provides splash protection rated to IP44. Small dimensions and a lightweight headband make the lamp practical for camping, outdoor work, cycling and any hands-free tasks that require both bright and low-power illumination.

Advantages

The aluminium housing offers a balance of durability and low weight while the swivel head allows the lamp to be used either mounted on the headband or held as a compact flashlight. Rechargeable power via USB and an 800 mAh Li‑Ion cell eliminate the need for disposable batteries and simplify recharging in the field. Five brightness settings plus a red-light mode give flexible control over beam intensity and preserve night vision when needed. IP44 splash protection makes the lamp usable in light rain and damp outdoor conditions.

How to use

Turn the lamp on and cycle through brightness levels to select the required lumen output; access the red-light mode when reduced glare or preserved night vision is required. Recharge the internal battery using a USB cable connected to a standard USB power source; charging status is indicated by the lamp’s built-in indicators. Allow the battery to fully charge before first use for optimal performance.

Usage recommendations

For prolonged outdoor use, select a lower brightness setting to extend runtime and reserve high-power mode for short, high-intensity tasks. Keep charging contacts and the USB port dry and clear of debris; avoid submersion as the device is splash resistant but not fully waterproof. Store the headlamp in a dry place at moderate temperature when not in use to preserve battery life.
