Flipo's Radius Zoom makes hands-free illumination a snap for any outdoor activity or indoor project. The Radius Zoom has a twist focus lens with a 150-lumen COB LED for narrow or wide beams. Two clips secure the contoured body of the Radius Zoom on the brim of a cap, hat or hardhat for hands-free use. The lamp pivots up to 90-degrees and has 3 illumination modes - high, low and flashing - activated by a conveniently located push button. Measuring approximately 3 3/4" x 2 1/4" x 1 3/8", the Radius Zoom requires 3 AAA batteries, (included), and can be used as a handheld flashlight if needed.
