S50 Sheath
-
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 Power
Options to stay ready. With COAST Dual Power technology, you have the choice to power your light with USB-rechargeable batteries or with standard alkaline batteries.
-
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.
-
Flex Charge
Power up on your terms. Lights with COAST Flex Charge technology feature a rechargeable battery that can be recharged either inside or outside the light. A simple USB connection to either AC or DC ensures you can always get juice.
-
High|Medium|Low
Control your light power with the push of a button. Cycle between full light, medium light and low light options.
-
Magnetic Tail Cap
Attach the light to magnetic surfaces. COAST lights with a Magnetized Tail Cap have an integrated magnet that enable you to affix the light to magnetic surfaces for easy storage or hands-free use.
-
Pure Beam Focusing Optic
Pack two powerful beams into one and seamlessly transition—with no halos or hot spots—between short and long-range viewing. COAST’s patented focusing technology adapts to your need. The Ultra View Flood beam delivers edge-to-edge clarity in a broad circle, and the BULLS-EYE™ Spot Beam sends a sharp ray of light at a distance with a transitional halo around the spot to increase the effective viewing area.
-
Twist Focus
Dial in the shape of light you need for the situation. COAST’s TWIST FOCUS™ system makes it easy to move between spot and flood beams by simply rotating the head of the flashlight.
