This is the ZHIYUN FIVERAY M20C COMBO 20W RGB LED light for photography. I prepared it for a single shoot and am selling it now that I'm finished using it. It's very small, yet boasts a high output of 20W. It also has a built-in cooling fan and a significantly thinned heat sink to optimize airflow. CCT: 2500K～10000K, TLCI≥96, CRI≥94, peak illuminance of 1950 lux, making it very bright with reduced flicker and a wide range of color temperature options. This product combines RGB and HSI dimming functions, allowing for light painting with a single touch. It features 10 creative lighting effects, music mode, and synchronized speed and temperature adjustment. Color settings can be adjusted on the unit itself, but the app installed on your smartphone makes it easy to intuitively set colors, making it very user-friendly. This product is the COMBO version, so it comes standard with an extension bracket, USB-C cable, diffuser, honeycomb grid, barn doors, and a logo-printed drawstring bag. The diffuser, honeycomb grid, and barn doors can be purchased separately, but it's more convenient to have them included from the start. Especially the grid and barn doors are great for controlling the direction of light. I've only used it about 3 times, so I don't think the battery has degraded much. It's a much better deal than buying new. ★Please Read★ Regarding the selling price, I do not accept price negotiations.
