Product description

The Ulanzi L023 40W PRO COB Fill Light is a compact yet powerful bi-color LED light with adjustable color temperature, built-in battery, and a 50W overclock mode—ideal for portable video and photography lighting.

The Ulanzi L023 40W PRO COB Fill Light delivers professional-grade lighting performance in a compact, pocket-sized design. Featuring bi-color COB LED lamp beads, it offers a wide adjustable color temperature range from 2500K to 6500K with a CRI of 95+, ensuring accurate color reproduction for video, photography, livestreaming, and content creation.

With stepless brightness control from 0–100%, this light allows precise adjustment to suit any shooting environment. In normal operation, it delivers 40W of output, while Overclock Mode boosts power up to 50W for maximum brightness when needed. At full 50W output, the light runs for up to 50 minutes, while lower brightness levels extend runtime up to 3 hours.

The built-in 3400mAh battery enables true wireless operation, making the light perfect for on-location shoots. Charging is supported via DC input or USB-C PD (65W fast charging), allowing quick recharging in approximately three hours. When charging during use, the light maintains a maximum output of 40W.

Designed for flexibility, the L023 weighs just 490g (1 lb) and can be handheld or mounted on a stand using the 1/4"-20 threaded mount. A Mini Bowens mount allows quick attachment of the included reflector and diffusion dome for softer, more even lighting. Additionally, 8 built-in lighting effects provide creative options for cinematic and social media content.
