The Pak-Lite SUPER Glow has the Super Glow-in-the-dark plastic cap and the same super bright white LEDs used in the Pak-Lite Super models. With its flat sides, the Pak-Lite Super can stand, lay on its side, mount to your bike's handle bars (see bike mount sold seperatily), fit in your coin pocket or shirt pocket, and mount almost anywhere with velcroe (sold seperatily) making it a very versatile flashlight! Like natural sunlight, the brilliant white light emitted by these LED bulbs reveals colors in their true sense. With the glow-in-the-dark cap, you can charge the cap up with any white, UV, or blue light source (including a bit from itself). Then place the Pak-Lite on your night stand. For the next few hours will be glowing to assist in finding your flashlight. White LEDs are the best choice for a general purpose flashlight, and they also work great for reading, walking, viewing maps, night-light in hotel rooms when traveling abroad, etc... The Pak-Lite SUPER may be used with any 9v battery, but performance choose the Pak-Lite Lithium Battery or the Made In USA Duracell Alkaline battery.
