The UltraFire is a very high power UV light for professional use - and is nothing like inexpensive UV flashlights you see with clusters of LEDS in them. Instead of an array of standard UV LEDs, the UltraFire UV flashlight uses a recently developed single, 3 watt high power LED chip. This chip produces an intense UV beam unlike any other flashlight.
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 switch is sealed, and self-cleaning. The flashlight head is a machined anti-roll shape to keep it in place when set on uneven surfaces.
The 3 watt high power UV  LED will of course last a lifetime.
For maximum power, the UltraFire uses two CR123A batteries. The UltraFire has a 1 year warranty, and is water resistant.
When you need the highest UV intensity in the smallest possible package, the UltraFire will fill your requirements.
