This lightnis made from aircraft grade aluminum, which makes it light weight and extremely durable. It has rubber gaskets throughout that allow it to be submerged in water and still work. It uses a 18650battery that last a fair amount of tine depending on brightness and whether or not its in UV mode. The UV mode is by far the moat interesting as rhis flashlight features a zoom so you can focus the uv beam and look for bet stains, bidy fluid or if your like me you can use it to activate glow lights or glow in the dark paint.
When shined on glow lights or paint it super charges the particles sok they not only glow brighter but the glow also last longer. Highly recommended for halloween time.
