The LIGHT² R4 is a compact, rechargeable pen light built for durability and versatility. It features a 304 stainless steel casing paired with a precision-machined body, powered by a 13450 rechargeable lithium polymer battery that can be conveniently charged via a standard 12V/24V car cigarette lighter socket.

Equipped with a high-performance Cree LED chip, it delivers up to 320 lumens of bright light with a 150-meter beam distance and offers three lighting modes (High / Low / Strobe) via its multi-mode dynamic switch. The light runs for up to 3.3 hours on low mode (1 lumen) with a full charge time of 4-6 hours.

Designed for practical use, it is IP45 waterproof and shockproof (tested to 1m drop resistance) yet lightweight at only 89g, including the battery, making it ideal for daily carry, emergency use, and automotive applications.
