Safe for use in Ex-Zone 1/21 areas and with a battery life of up to 45 hours (on low power), the rechargeable Ledlenser EX7R will keep a bright light on the job no matter how long your work shift is. Ledlenser patented Advanced Focus System allows you to transition light from a broad flood beam to a sharply focused long-distance beam, allowing you to control the powerful 220 lumens of output. The magnetic power switch makes operating the flashlight easy even while wearing heavy work gloves.
