Arrow Fastener 500LM Rechargeable Headlamp AOT03004A 90° Adjustable USB-C

What the headlamp is and who uses it

The Arrow Fastener 500LM Rechargeable Headlamp is a hands-free light built for outdoor activities such as camping, running, hiking and fishing. It delivers a maximum output of 500 lumens through both spotlight and floodlight beams, plus red-light modes that preserve night vision. A USB-C port recharges the internal lithium-ion cell, and the elastic headband fits securely over a cap or bare head. Workers needing reliable close-range illumination will also find it practical.

The specification that decides fit

The head tilts through a 90 degree range so you can point the beam straight ahead or down at your feet without moving your head. Six lighting modes cover spot, flood, combined spot-plus-flood, red flood and strobe variations for signalling. A rotary knob selects the main mode while a centre button handles stepless dimming and flashing functions. The motion sensor lets you wave a hand to switch the light on or off when gloves make buttons hard to press.

Behaviour during extended use

Stepless dimming lets you lower output to match the task, which stretches battery life far beyond the maximum 500 lumen setting. The red flood mode draws less power and avoids blinding companions around a campsite or on a trail. Because the battery charges via USB-C, you can top it up from a power bank during a multi-day trip without carrying spare cells. The 90 degree hinge stays firm after repeated adjustment so the aim does not drift while you move.
