Designed to deliver heavyweight performance from a compact frame, the three-mode XPH27R shines up to 410 lumens and weighs just 2.6 ounces. This headlamp is built from top-grade aluminum and features a dust- resistant and stormproof body that rolls in its bracket for dynamic directional lighting-which can also detach to become a handheld flashlight with a built-in magnetic tail cap and real-time power indicator. Featuring Coast's Rechargeable Dual Power system for versatility on the job, the headlamp runs on a Coast Zithion-X rechargeable battery (charging cable included) or CR123 lithium batteries (Purchased Separately). With Coast's commitment to quality, the XPH27R Headlamp is impact resistant, weather resistant and its LED is virtually unbreakable. Backed by COAST's lifetime warranty against defects in materials and workmanship
