ROCKBROS Bicycle 3000 High 6 Dimming Up to 30 Hours of High IPX6 Aluminum Alloy Flashlight for Road Power Earthquake and Night Fishing Headlight,

[3000 Lumens of Brightness & 6 Dimmable Modes] ROCKBROS bike lights feature two 30-watt LED bulbs and two modes: low beam and high beam. When both low and high beams are on simultaneously, they deliver an ultra-high brightness of 3000 lumens. 1. Low beam: 4 constant modes (A: 1500 lumens, B: 800 lumens, C: 400 lumens, D: 200 lumens) + flashing mode (200 lumens). 2. High beam: 2 constant modes (E: 800 lumens, F: 1500 lumens). Switch between modes with each click of the switch. The light also has a memory function, so it will resume from the last recorded mode upon restart (low beam only). *Note for first-time use: Press and hold the low and high beam switches simultaneously for about 5 seconds to unlock (the light will go from flashing red to green). [10,000mAh Large Capacity] This road bike light has a built-in 10,000mAh large capacity, and after a single full charge, it can be used continuously for 2.3 to 30 hours depending on the lighting pattern. [Temperature control + low voltage protection] The light is equipped with a temperature measurement element, so if the internal temperature exceeds 70°C, the mode will automatically downshift. If the temperature exceeds 100°C or if the voltage is low, the light will shut down. When the remaining battery level is below 15%, only 400LM mode and 200LM mode will be used. [Design Details] 1. Aluminum Alloy: Made of aluminum alloy for impact resistance, excellent abrasion resistance, and corrosion resistance. 2. Anti-Glare: Beam distance approximately 200m, beam angle approximately 90°, and anti-glare lens. It cuts the light distribution upward, preventing oncoming traffic from being dazzled while riding, improving safety for cyclists. 3. Type-C Rechargeable: Fully charged in just 5.5 hours (battery level indicator included). 4. IPX6 Waterproof: This bicycle headlamp can be used in bad weather, allowing you to ride without panicking even in sudden rain. *Note: Do not use for long periods in downpours or underwater. 5. Easy Installation: Simply align the light with the handlebar mount, insert, and rotate to securely attach.
