| This flashlight produces UV light, so it is not useful for normal illumination tasks. This is a higher quality version of the UV light that we have been selling for several years now. It is VERY useful for tasks requiring UV light, such as currency authentication, spotting scorpions, and Crime Scene Investigation work. Uses 3 AAA batteries, not included. Aluminum Construction with pewter finish. 12 Bright UV LEDs, tailcap click-on button operation. Significantly brighter than the Inova X5 UV Size: 3.75" long x 1.14" head diameter, 2.4 ounces (9.5cm x 2.9cm, 67 gm) Note: Batteries not included |
