The Flashlight body itself is machined from high-quality, aircraft grade Aluminum with neoprene "O" rings on the flashlight head and battery compartment seams. The rear switch is sealed, and self-cleaning.
The 12 watt high power UV emitters will of course last a lifetime.
For maximum power, the UN Pro UV uses a built-in rechargeable lithium battery. It is easily recharged via any USB port or charger. Charging cable is included. Also included is a pair of UV glasses which protects your eyes from the intense UV light as well as making anything viewed under the UV light much more discernible. The flashlight has a 1 year warranty, and is water resistant.
When you need the highest UV intensity in the smallest possible package, this flashlight will fill your requirements.
