SD4A is a solid and durable mini searching flashlight, running out up to 1000 lumens. High strength aerospace aluminum alloy construction with anti-scratching type HAIII military grade hard-anodized finish makes SD4A lighter and tougher. Cylinder-like “unibody” design is simple and decent. Stainless steel anti-rolling head retaining ring ring offers more premium quality, which of course, is more sturdy, durable and eye-catching. It’s anti-dropping and waterproof, workable when completely wet.
