This compact silicone bike headlight employs the NEWEST COB (chip-on-board - see below) LED technology for a super bright white light. It will dazzle you and anyone in your path! Never change batteries or bulbs again! Micro-USB rechargeable, so just plug it in anywhere for a fresh start. LED bulbs last 100,000 hours, so never change those again either! The light includes a low-battery indicator, so you know when it is time for a charge. All charging accessories and mounts are included. Silicone casing means it is more durable and can withstand falls and other mishaps. It is also water resistant, so if you get caught in a rainstorm, it will still be lighting the way for you! The light has Steady and Flash modes. Steady lights the way, Flash grabs attention and conserves battery power. Battery is a rechargeable 3.7V li-ion 300mAh. Imported. "Chip on Board (COB) is the most recent development in LED technology, using chips with multiple diodes (typically 9 or more). There is no casing with COB technology, which enables a much denser LED array of light compared to SMD."
