Overview
The Godox KNOWLED MG4KR RGB LED Monolight is a powerful 3250W RGB point-source fixture designed for studio, film, and television productions. As the full-color sibling of the bi-color MG4K, the MG4KR delivers exceptional output, full RGB capabilities, precision color control, and a rugged IP65-rated construction. Its separated controller and refined cooling system enable reliable performance in demanding professional environments, while G-mount compatibility ensures full integration with the KNOWLED modifier ecosystem.
Full RGB Lighting
The MG4KR offers a wide 1800–10,000K color temperature range with full RGB output, ±100% green/magenta shift, and 91% Rec.2020 color space coverage. It features 0–100% dimming with four dimming curves, ensuring accurate and controllable illumination for high-end productions.
Exceptional Brightness
With the included 20° reflector, the light produces 225,100 lux at 3 m (5600K). When using the same reflector, it delivers impressive color-specific output levels of 24,600 lux (red), 40,500 lux (green), and 13,400 lux (blue) at 3 m. This performance surpasses comparable RGB fixtures and approaches traditional 4K HMI brightness.
Intuitive & Advanced Control
Control options include onboard adjustment, DMX, CRMX, Bluetooth, NFC pairing, and app control via the Godox Light or KNOWLED mobile apps. The system offers Ethernet support and up to 60 m of wireless Bluetooth range for flexible operation across large sets.
Consistent Performance
The advanced cooling mechanism regulates temperature for optimal output and extended runtime. A wide 110° beam angle allows smooth, even bare-bulb fills, while Smooth Mode ensures fluid dimming transitions. High-speed mode offers flicker-free operation with no frame rate limits.
G-Mount Modifiers
The MG4KR supports the complete G-mount accessory ecosystem, ensuring compatibility across KNOWLED fixtures such as the MG6K, MG4K, MG1200R, and MG1200Bi. The included reflector and optional additional modifiers allow precise control of beam shaping and intensity.
AC Power & IP65 Durability
Built for studio and controlled environments with access to AC power, the MG4KR includes AC and DC power cables. Its robust IP65 design protects against dust, rain, and extreme weather. Delivering 3250W of RGB power, the fixture provides class-leading performance in a compact, production-ready housing.
