CATEYE AMPP USB Rechargeable Bike Light 500 Lumen Headlight

In this review of the CATEYE AMPP USB rechargeable bike light, the bottom line is simple: it is a versatile, bright headlight suited to commuters and cyclists who need dependable daytime visibility and strong night illumination. The light's single biggest selling point is the combination of a 500 lumen LED with OptiCube lens technology and wraparound side visibility, which makes the rider more conspicuous from multiple angles. Practical features like USB-C recharge, a 2200mAh battery and mode memory round out a package that balances safety and convenience for everyday riding.

Key Features

• 500 lumen high beam: A high intensity LED with OptiCube lens delivers a wide, well-defined beam that illuminates the road and improves detection by oncoming traffic.
• Wraparound side visibility: The lens design provides visible light to the sides so the rider is easier to spot at intersections and from lateral angles.
• USB-C rechargeable battery: The 2200mAh Li-ion pack recharges in about 4 hours and offers up to 60 hours of runtime on the lowest setting for long-term use between charges.
• Five selectable modes: High, Middle, Low, Daytime HyperConstant and Flashing cover commuting, daytime running and tactical use with a mode memory to return to the last used setting.
• Quick access to full power: Double-clicking from any mode instantly activates the full 500 lumen high mode for brief bursts of maximum visibility.
• Easy mounting: The adjustable FlexTight bracket fits handlebars up to 35 mm and the improved release button makes removal and charging straightforward.

Who It's For

The AMPP light is aimed at urban commuters, road cyclists and mountain bikers who want a compact, lightweight headlight that offers strong forward output plus reliable side visibility. Riders who value quick recharging and the convenience of USB-C will appreciate the 4 hour recharge and the three-level battery indicator for planning long rides.

Less suitable users are those who need extreme long-duration maximum output for multi-day backcountry use without recharging, since battery life varies by mode and some customers report mixed experiences with runtime. If you require integrated bike electronics or helmet mounting as a primary feature, consider lights designed specifically for those setups.

Cons
