INOVA X5 Ultraviolet Flashlight

Got a CSI fantasy? Then just drop one of these in your bag of tricks and start shining it around in spare moments. Featuring five high-power LEDs backed by two 123-sized lithium batteries, the X5 puts out a surprisingly strong UV flood, capable of fluorescing most common hidden inks, watermarks, and other hidden aspects of your daily crime scenes. Bored at lunch? Dump out everybody’s wallets and check out the hidden markings on currency or your video club card. Need a good scare? Turn off the lights in your bathroom or kitchen and start looking around with the X5. I’m still reeling.
