ACRUNU 3250 Lumen Rechargeable Bike Lights — 180° Wide Beam Front + USB-C Tail Light, 8000mAh

ACRUNU's rechargeable front and rear bike light set delivers a 3250-lumen wide beam and a USB-C taillight to boost night visibility for commuting, road, and off-road cycling.

Designed to upgrade your after-dark rides, this kit pairs a high-output front headlight with a compact rechargeable taillight. The front unit casts a broad 180° beam for both forward and peripheral illumination, while the rear light offers multiple flash patterns and long runtime. Aluminum construction, IPX4 splash resistance, and tool-free mounting make it practical for daily use on a wide range of bikes and e-bikes.

How bright is the front light and how far will it reach?

The front lamp produces up to 3250 lumens and is engineered to spread light across a wide 180° angle, improving side visibility as much as forward throw. The manufacturer rates the maximum beam distance up to about 300 meters under optimal conditions, making it useful for fast road or trail rides where seeing obstacles early matters.

• Peak output: 3250 lumens for high-speed or poorly lit routes
• Wide 180° beam to illuminate peripheries, not just the center
• Rated beam throw up to ~300 meters for early obstacle detection
• Four selectable modes to tailor brightness and runtime

What battery life and charging options are available?

The front light houses an 8000mAh rechargeable battery that provides extended runtimes—up to roughly 11.8 hours depending on the selected mode. It charges via USB-C in around five hours and doubles as an emergency power bank for compatible phones or devices while you're on the road.

• 8000mAh capacity for long group rides or multi-day commuting
• Approximately 5-hour full recharge with USB-C input
• Power bank function to charge mobile devices in emergencies
• Multiple modes let you trade brightness for longer runtime

How easy is installation and will it fit my bike?

The front light mounts to handlebars using a secure dual bracket designed for 22.2–33 mm round bars, and the rear light uses a flexible strap for quick attachment to seatposts, racks, or bag straps. Both mounts are tool-free for fast transfers between bikes or removal when parking in public spaces.

• Dual front bracket fits most road, mountain, folding, and e-bike bars
• Flexible rear strap secures to a variety of seatposts and luggage points
• Tool-free mounting for quick installs and removals
• Durable aluminum housing resists daily wear and light impacts

Will this set handle wet weather and everyday use?

The headlight’s aluminum alloy shell and IPX4 water resistance rating protect against rain and splashes during routine outdoor use. While it's built for commuting and trail conditions, avoid prolonged submersion and store the lights dry when possible to prolong their service life.

• Aluminum construction for improved heat dissipation and durability
• IPX4 splash resistance suitable for rain and wet commutes
• Robust lens and button design for frequent operation
• Rear light visibility up to approximately 150 meters in flashing modes

Who is this for: Cyclists who ride in low-light or mixed-weather conditions and want a reliable, rechargeable lighting solution that balances strong forward illumination with rear visibility. The set is ideal for daily commuters, night-shift workers, e-bike riders, touring cyclists, and anyone wanting a quick-install light package that can also serve as a power bank in a pinch.
