SD4A is a solid and durable mini searching flashlight. Although at just 4.41inches and weighing less than 6.28oz, SD4A can deliver a strong output reaching to 1000 lumens max. To meet different illumination needs, we made two types of LED available: CREE XM-L2(U2) and Cree XP-L HI LED.

High strength aerospace aluminum alloy construction with anti-scratching type HAIII military grade hard-anodized finish makes SD4A lighter and more tough. Cylinder-like “unibody” design is simple yet decent. Stainless steel anti-rolling head retaining ring offers more premium quality, which of course, is more sturdy, durable and eye-catching. Exquisite square-cut knurling feels chic and delicate. Invisible lanyard hole is smartly chamfered on the thermal dissipation zone without doing any harm to the overall beauty of SD4A.

What’s more, SD4A enjoys strong university as it can run run on basically any type of battery including 4x AA Ni-MH with battery holder or D-cell. Its heat-dissipating zone is deep and large enough to ensure better heat dissipation. Also, the front side double-switch not only provide one-handed operation and easy access to all functions, but strengthen its safety performance as the light can be locked if you depress and hold both buttons for more than 2 seconds.

We promise that you won’t be disappointed at SD4A when you have it in hand.
