The Ledlenser EXH8R rechargeable headlamp offers excellent safety in any Ex-Zone 1/21 areas where flammable gases, vapors or dust clouds hazards occasionally occur. Not only is it lightweight and comfortable to wear but the Ledlenser patented Advanced Focus System allows you to transition light from a broad flood beam to a sharply focused long-distance beam. The powerful 200-lumen light beam illuminates those dark and dangerous places, helping you stay safe and able to get the job done.
