The SPERAS U4 is a compact, rechargeable keychain flashlight that combines a powerful front spotlight, a versatile white/red COB side light, and a magnetic tail in a lightweight everyday carry design.

Delivering up to 500 lumens with a maximum beam distance of 100 meters, the U4 provides useful illumination for everyday tasks, outdoor activities, and unexpected nighttime situations. Its side COB light adds broad-area lighting for close-up work, while the red light offers an alternative for nighttime use and emergency signaling.

Measuring just 62mm long and weighing approximately 23g, the U4 is easy to carry on a keyring, backpack, or in a pocket. USB-C charging, a built-in battery indicator, and electronic lockout make it a practical companion for daily use.

Dual-Light Design: Spotlight and COB Side Light

The SPERAS U4 combines two lighting systems to handle different everyday tasks.

Front Spotlight – Up to 500 Lumens

The front spotlight delivers up to 500 lumens and reaches a maximum distance of 100 meters.

Its focused beam is useful for checking dark paths, locating objects, walking outdoors, and illuminating areas beyond immediate reach.

White COB Side Light

The integrated COB side light provides broad, close-range illumination for tasks that benefit from a wider beam.

Ideal for:

• Car and roadside repairs

• Camping and tent setup

• Reading and household tasks

• Equipment inspection

• Hands-free work when attached to a metal surface

Red COB Light

The red side light provides an alternative to white illumination when working in darkness or signaling in an emergency.

Available red-light modes include steady illumination and flashing.

Magnetic Tail for Hands-Free Lighting

The U4 features an integrated magnetic tail that attaches to suitable ferrous metal surfaces.

This allows you to position the flashlight as a small hands-free work light, freeing both hands for practical tasks.

Attach it to a compatible metal surface under a car hood, inside a workshop, or near camping equipment to illuminate your work area.

The magnetic attachment works on suitable magnetic metal surfaces; it will not attach securely to every material.

Ultra-Compact Everyday Carry

At approximately 62mm long and 23g, the SPERAS U4 adds minimal bulk to your everyday carry setup.

Its integrated keyring loop allows convenient attachment to keys, bags, and backpacks, keeping a useful light readily accessible.

The compact size makes it suitable as a backup flashlight for commuting, travel, camping, and everyday emergencies.

USB-C Rechargeable Battery

The U4 features a built-in rechargeable lithium battery and a USB-C charging port.

A full charge takes approximately 1.5 hours under the manufacturer's specified charging conditions.

The integrated charging port is protected by a cover to help keep out dirt and debris during everyday carry.

Because the battery is built in, it does not require routine removal or replacement during normal charging.

Battery Level Indicator

The illuminated switch ring provides a quick indication of the remaining battery charge.

• Solid green: 75% or more

• Flashing green: 50%–75%

• Solid red: 25%–50%

• Flashing red: 25% or less

This indicator helps you decide when to recharge the flashlight before heading out.

Electronic Lockout for Pocket Safety

The U4 features a four-click electronic lockout to help prevent accidental activation during transportation.

When the flashlight is off, click the side button four times rapidly to lock or unlock it.

In lockout mode, accidental button presses trigger two brief flashes from the main light to indicate that the flashlight remains locked.

This function helps prevent unnecessary battery drain when the light is carried with keys or other everyday items.
