The ROCKBROS JHL 1200 is a versatile bicycle light designed to provide clear visibility during night rides. It utilizes 5050 20W lamp beads to reach a maximum brightness of 1200 lumens, while a wide-angle spherical anti-glare lens with a cut-off line ensures that you illuminate the road without blinding oncoming traffic. Built from a combination of aluminum alloy and engineering plastic, the main body weighs 154g and measures 107 x 26 x 30 mm. The device is powered by a 3.7V 5000mAh lithium-ion battery that charges via USB Type-C in about 3 hours. Depending on your needs, you can choose from four modes: the high setting lasts 3 hours and 20 minutes, the medium provides 500 lumens for 4 hours and 20 minutes, the standard mode offers 330 lumens for 5 hours and 20 minutes, and the eco mode extends runtime to 8 hours at 150 lumens. For added flexibility, the light features a detachable body that allows it to function as a handheld flashlight. It comes with a quick-release 360° rotating base for easy positioning and an anti-misoperation lock key to prevent accidental power changes. With an IPX6 waterproof rating, this light remains reliable even when you are caught in heavy rain.
