Briefly increases the light output to maximum brightness and distance.

The total quantity of light emitted in every direction from a source of light; measured in lumens.

Beam pattern affects how much you can see within the area of light thrown from the headlamp. Wide beams are good for close-up; spot or focussed beams are good for long range visibility.

Indicates the degree of protection against liquid. IP X1: Dripping water while in normal operating orientation; IP X4: Splashing water; IP X5: Water jets; IP X6: Powerful water jets; IP X7: Immersion up to 1m ≤ 30 minutes; IP X8: Suitable for submersion as specified by manufacturer.

Rechargeable lights give you hassle-free recharging with almost any power source. Replaceable batteries provide instant power, but you’ll need to bring extra batteries, recycle used ones and buy new ones.

On regulated lights brightness is consistent, and does not decrease gradually as the batteries are drained.
