For DJI Osmo Action 6 5 Pro 4 3 STARTRC Small Cube Fill Light(Black) Features 1. One-Click Quick Release, Universal Compatibility: Designed specifically for the ACTION quick-release ecosystem, it features both a 14-inch screw hole and a cold shoe adapter, allowing for seamless switching between DJI ACTIONNANO360 action cameras, cameras, desktops, tripods, and handheld use, adapting to most shooting scenarios. 2. Soft Light and Beauty Enhancement, Radiant Complexion: Built-in high-CRI LED beads and an external soft light diffuser transform harsh direct light into even, soft diffused light, naturally brightening skin tone and smoothing skin texture for a "physical-level skin smoothing" effect. (The soft light diffuser reduces light directionality, making the transition between highlights and shadows on the skin surface smoother.) 3. Four Color Temperature Presets, Ambiance Master: Provides four professional color temperature settings, from cool white light (7500K) to warm yellow light (3000-3500K), switchable with a single click. Cool light is refreshing and clear, while warm light is cozy and enhances complexion, easily creating the ideal lighting for different scenes. (First setting: cool white light 7500K, second setting: natural light 5000-6000K, third setting: warm white light 4500-5000K, fourth setting: warm yellow light 3000-3500K. It can simulate the daylight color temperature trajectory by adjusting the redblue light ratio. Warm light 3000-5000K: increases the proportion of red light, neutralizing the yellow tone of Asian skin for a rosy complexion; Cool light 5000K-7000K: increases the proportion of blue light, brightening dull skin and enhancing the transparency of the image.) 4. Flicker-Free Stepless Dimming, Brightness at Your Fingertips: Supports long-press stepless dimming, providing soft, flicker-free light that is gentle on the eyes. Whether fine-tuning the ambiance or meeting the needs of high-definition shooting, brightness control is completely in your hands. (Double-click to switch onoff
