The Ulanzi LM-P40 Bi is a versatile bi-color video light designed to provide reliable illumination for content creators and videographers. It features a total of 120 LED diodes, split evenly between warm and cold tones, allowing you to adjust the color temperature from 2500K to 9000K to match your environment. With a power output of 40W and a brightness reaching 14,000 lux at 0.3 meters, it delivers a wide 160-degree beam that ensures your subject is well-lit, while a CRI/TLCI of 95 keeps colors looking natural and accurate. Constructed from a blend of ABS and PC, the light is compact and weighs about 352g, making it easy to handle during long shoots. It is powered by an integrated 6400 mAh battery consisting of two 3200 mAh cells, which can provide up to 3 hours of light depending on your settings. To keep the device stable during intensive use, a built-in cooling fan manages the heat. You can recharge the unit via a USB Type-C port, and the battery even doubles as a power bank with a 5V 1A output to charge other small devices in a pinch. For flexible positioning, the chassis includes dual 1/4" threaded holes for both horizontal and vertical mounting. The package comes with a diffuser to soften the light, making it a practical choice for those who need a portable yet powerful lighting solution for interviews or vlogging.
