The ROCKBROS RHL3000 is a powerful bicycle headlight designed to provide clear visibility during night rides. It utilizes two 3570 30W lamp beads to reach a combined maximum illumination of 3000 lumens, featuring an anti-glare cutoff line that prevents blinding oncoming traffic. You can choose from six lighting modes, including four low beam settings ranging from 200 to 1500 lumens, which offer runtimes between 4 and 30 hours depending on the intensity selected. Constructed from a lightweight aluminum alloy, the unit weighs approximately 280g and is protected by an IPX6 water resistance rating for reliability in rainy weather. The light is powered by a 10,000 mAh battery consisting of two 21700 lithium cells, rechargeable via a USB Type-C port. This battery also doubles as a power bank, allowing you to charge other small devices through the tail output interface during your journey. To ensure longevity and safety, the device includes intelligent temperature control that downshifts at 70°C and shuts off at 100°C, alongside low voltage protection that limits output to 400 or 200 lumens when the battery drops below 15%. A built-in indicator light keeps you informed of the remaining power, while the fastener base with a rotation lock makes it simple to secure the light to your handlebars.
