Adjust light intensity to your circumstance. Featuring COAST Variable Light Control technology, the RL10 headlamp puts responsive lumens-control at your fingertips.

A dial on top of the light body allows you to gradually increase or decrease light output, peaking at 500 lumens from the white chip on board (C.O.B.) LED array. To prevent “night-blinding,” an anti-glare red LED option makes it easy to read in the dark or navigate with less reflection.

The battery housing located at the back of the non-slip head strap can be powered by three AAA alkaline batteries (included) or be upgraded to operate on a COAST ZITHION-X™ rechargeable battery (sold separately).

A rear-facing safety signal on the back of the battery housing shines in solid red or flashing red with its own on/off switch so that co-workers, passersby, or others can spot you easily in the dark.

Constructed of top-grade materials, the RL10 is IP54 water-resistant and dust-resistant and backed by a lifetime warranty. 

ALKALINE DUAL POWER

Each COAST Alkaline-Dual Power is compatible with COAST Extreme Performance alkaline batteries and other standard alkaline batteries. Each product can also be powered with a COAST ported ZITHION-X™ rechargeable battery. This offers you the convenience of alkaline and the cost efficiency of rechargeable battery.

 C.O.B. OPTIC

Get brilliant light tailored for specialized formats and use cases. COAST lights featuring Chip on Board (C.O.B.) technology cast a wide beam handy for up-close work—from a strip of LEDs built right onto the chassis, without a standard optic. 

DUAL-COLOR WHITE & RED BEAM

The right light for the moment. The Dual-Color White & Red Beam combines an all-white Utility Beam for general use with a red, anti-glare beam that prevents “night blinding” while also offering a tool for emergency signaling. 

HINGED BEAM

Up, down, or straight ahead. All COAST headlamps feature a hinged, tilting head so that you can adjust the light’s direction and see right where you’re looking.

LIGHT CONTROL WHEEL

Dial in your light output. COAST’s patent-pending variable light-control system puts you in control of your headlamp’s beam intensity, with a rotating sensor knob that detects a magnetic field inside the headlamp bezel.

VARIABLE LIGHT CONTROL TECHNOLOGY

Easily adjust headlamp light output. COAST Variable Light Control Technology provides three ways to precisely regulate beam intensity.
