Lightweight yet powerful, the FLX40R offers five modes, a focusing optic, and USB-C charging in a compact headlamp.
Shine two beams from one optic with PURE BEAM technology—seamlessly transitioning between Ultra View Flood and BULLS-EYE™ Spot Beams.
Adjust the beam shape—flood, spot, or anywhere in between—by twisting the bezel to focus the light exactly where you need it for any task.
Stay comfortable during long use with a breathable, silicone-lined mesh head strap that offers a secure, reflective fit for any task or condition.
Shine bright through rain, splashes, and storms with a rugged IP54-rated build that's water- and dust-resistant—ideal for tough, dirty jobs.
Rely on the built-in ZITHION™ rechargeable battery for strong performance and cost savings.
Recharge without any fuss by plugging power into the integrated USB-C port, offering fast, convenient charging when needed.
This light features standard modes plus COAST’s Turbo Mode, delivering overpowered brightness when needed most in critical moments.
Preserve power—the lock-out mechanism prevents the light from accidentally turning on when stowed away.
