The extra large magnetic switch on the Ledlenser EX7 is easy to operate even with the protective gloves on. It is also safe for use in Ex-Zone 0/20, meaning you’re safe in virtually any environment from tank to grain elevator with explosive gases or dusts. It features Ledlenser patented Advanced Focus System which allows you to transition light from a broad flood beam to a sharply focused long-distance beam. All this and a battery life of up to 45 hours and up to 200 lumens of light output.
