This tiny COB light is what many creators have been eagerly anticipating. The size of the light and the compactness of the carrying bag make it an easy go-to option for on-the-go lighting. The K&F Concept RC 60B is a 60-watt bi-color continuous LED video/photography light with a wide range of color temperatures, ranging from a warm 2700K to a cool 6500K. The knobs are exceptionally smooth and easy to adjust for brightness, color temperature, and modes. It includes a COB light, a handheld mount, a silicone soft light cover, and a reflector, along with long and short USB-C cables for charging.The built-in 4500mAh battery provides up to 45 minutes of usage at 100% brightness. Typically, I use these lights at less than 50% brightness in most cases. They are employed for product videography, photography, and talking head-style content creation. I appreciate the small detail of the expected battery life based on the current mode and brightness in use (refer to the photo).Overall, this is an excellent compact light at a reasonable price for its features. I own other similar 60-watt lights with fewer features that cost more.
