Dust Resistant
Take on any dirty work environment with this dust resistant light.
-
Pro-Tek Charging
Charge directly from AC, DC, and USB. Flashlights and headlamps with COAST PRO-TEK Charging include a direct-connect port for powering back up.
-
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.
-
Rechargeable Dual Power
Each COAST Rechargeable-Dual Power product comes with a ported ZITHION-X™ rechargeable battery or a non-ported ZITHION™ rechargeable battery and is compatible with either COAST Extreme Performance alkaline batteries or other brand-name battery types, depending on the product. This provides you the cost savings of using rechargeable and the flexibility of reverting to alkaline.
-
Storm Proof
Don’t worry about the weather. COAST lights that have passed the IP54-level resistance tests are splash-resistant and built with durable materials that stand up to nature.
