Lighten7 Diver U22A is a heavy duty underwater light for diving and more specific for underwater applications such as hunting. It is designed for over 50 meters water resistance. Adopted CREE XML-T6 4C warm tint LED, it generates yellowish light beam for over 800 lumens. The fully water proved side swtich controls on/off and 5 levels of output with SOS on double click. A battery indicator is located at side switch to alert user for different power level.
Powered by high capacity 1 or 2 x 26650 lithium ion batteries, the extension tube provides flexibility to adopt addtional battery to increase runtime. U22A can shine over 3 hours at 100% output which is sufficient for continuous usage.
Milled from solid rod of high grade 7075 aluminum alloy, and type III anodized surface that assures the durability and sturdiness. 4mm double thickness of armored lens provides additional strength from external impact and water pressure.

While U22A is also a stronghold on land usage from its sturdy design , powerful and longhaul illumination which is excellent for search & rescue, caving and cave diving.
