Overview
Brighter. Smarter. More Eco-friendly
The MG4K delivers exceptional brightness with half the energy of a traditional 4K HMI—achieving 25600Lux using just 2000W instead of 4000W. Shines brighter and more eco-friendly. Brighter than 4K HMI
2000 W Power Otput 
25600 Lux at 5m, 5600K (with MGR30 30°reflector)
Half The Weight Of 4K HMI
Weighing just 10kg, the MG4K delivers class-leading output in the compact size, making rigging, moving, and positioning on set faster and safer.
Highest Optical Efficiency
The Godox MG4K maximizes the optical efficiency with its advanced light engine. Featuring the industry's smallest emitting area, it delivers the highest efficiency, optimal luminous efficacy (110lm/W) and maximum brightness in its power class.
Smallest Light Source 63mm diameter
MG4K shrinks the emitting area to the smallest, achieving a near 'point-source' to maximize brightness and optical efficiency.
No Extra Components Needed
Engineered for maximum efficiency, the MG4K delivers minimal energy loss and eliminates heat buildup, ensuring consistent, reliable illumination that maintains peak performance even during extended use.
Optimal Brightness Enhancement
Engineered with optimal optics, the MG4K paired with the 15°reflector achieves highly efficient light concentration, delivering up to 36.7 times brightness enhancement.
124000lux at 5m, 5600K (with MGR15 15°reflector)
Efficient Cooling For Stable Performance
Engineered for high-performance in a compact form, Godox’s advanced cooling system delivers faster heat dissipation by 67%, keeping the MG4K cool and reliable during every shoot, ensuring consistent performance and a longer lifespan.
Precision Lighting & Flexible Operation
The MG4K provides precise brightness, accurate color reproduction, 0.1% dimming, and versatile operation, meeting the demanding needs of film and television productions.
+-100% Green-Magenta shift
The MG4K features -100%~100% GM shift and adjustable CCT from 2, 800K to 10000K, allowing precise color tuning for accurate scene colors.
Flexible Control Options
The MG4K supports DMX, CRMX wireless, Ethernet, on-board controls, and app operation, providing versatile and convenient control in any production environment.
