Just picked up one of these and must admit that I am very impressed with the optional 6/55 lumens packed into this little dude. The Nite Ize INOVA X1® is a serious flashlight that offers exceptional engineering and illumination for its compact 4-inch size. Its patented optical system, precision machined aluminum reflector with thermal interface provides superior light projection and visibility. Updated performance and new dual-mode functionality provides long hours of either High or Low power light output. Featuring a uniform focused spot with flood beam pattern that has an effective range of 223 feet, its beam can be also be seen in the dark for up to 1.5 miles. Perfect for keeping close at hand in a glove box, purse, brief case, backpack, and everywhere you go. Probably the best pocket/glovebox light you’ll find for under $40 that runs on a single AA battery (included). Another very cool option for you forensic scientist out there is the x5 UV model.
