A CAMPING ESSENTIAL: Part lantern, part tumbler holder, the GLOW lights the way as you walk around the campsite sipping your coffee — no extra flashlight required. Both lightweight and strong enough to carry 20 and 30-ounce tumblers filled to the brim. 3 DIMMABLE LIGHT MODES: Choose the COB Task Light setting for 220 lumens of forward-facing illumination, light your path with the bottom-facing Lantern mode (130 lm), or use both at the same time for 350 lumens of portable, mug-mounted light. SECURE, COMFORTABLE GRIP: With an ergonomic design, water-resistant build, rubberized non-slip grip, and an insert for carrying 20-oz mugs, this light-up handle for 30 oz tumblers is easy to carry while walking the dog; no more tripping in the dark. HANDY FEATURES: The GLOW has Power Memory Recall to remember your last light mode, with Direct-to-Lantern functionality so you don't accidentally shine the light in your friends' eyes at the campfire; conveniently powered by 3 AAA batteries (included).
