The K&F CONCEPT 135 LED RGB Video Light is one of the best compact lights I've tried in this price range. Its small size and low weight make it perfect to always carry with you, even in a light backpack or jacket pocket. Excellent battery life: the integrated 5000mAh battery lasts quietly for several hours even at full brightness, and can even be used as a power bank in case of emergency. The USB-C interface ensures fast and modern charging. The quality of the light is very good: 2812 lux at 0.3m are more than enough for studio or mobile work, and the 135 LEDs offer a faithful color rendering (CRI 96+) and homogeneous. Plus, thanks to the full RGB mode and 13 preset special effects, you can really play with the atmosphere of your creative shooting or shooting. The rear display is clear and shows color temperature, saturation, selected effect and battery status in real time. The control with the wheel and buttons is simple and effective, although a slightly more intuitive interface would have been the best. Small drawback: a protective case is missing in the package, which would have been very useful to protect it during transport. In conclusion, it is a versatile, powerful and well-built light, perfect both for those who are starting out and for those who already have experience and want something compact but effective. Recommended.
