At IBC 2025 in Amsterdam, Godox introduced the KNOWLED MG4K Bi-Color LED Monolight as a smaller but powerful option next to the MG6K. With 2000W of output, it matches the brightness of traditional 4K HMIs but is lighter and easier to set up.
The MG4K also brings smart features like advanced cooling, G-mount compatibility, and IP65 weather protection, making it a strong choice for modern film, photo, and content production.

1. MG4K Brightness and Performance
Brightness is one of the most important factors in any professional LED light. The MG4K delivers up to 25,600 lux at 5 meters using a 30° reflector, and it can reach 124,000 lux with the optional 15° reflector. To put that into perspective, this is enough light to illuminate large sets or outdoor scenes, similar to what older 4K HMI lights would produce, but at half the power and weight.
2. Lightweight Design for Easy Handling
At just 10kg (22 lbs) without the yoke and 12.5kg (27.5 lbs) with it, the MG4K is about half the weight of a standard 4K HMI. This compact build makes rigging, moving, and positioning faster, safer, and manageable even for a single operator.
3. Precision Color Control of the Godox MG4K
One of the standout features of the Godox MG4K is its color control flexibility. The light offers a range from 2800K (warm) to 10,000K (cool), allowing you to adjust it for sunrise or daylight effects. You can also fine-tune the green/magenta balance, which is essential for matching multiple light sources on set.
The dimming is precise to 0.1% so that you can achieve subtle lighting changes without flicker. This level of control is beneficial for filmmaking lighting and photography lighting where the smallest adjustments can dramatically change the mood and feel of your scene.
4. Advanced Cooling and Durability
LED lights can get hot, especially when running at high output for long periods. The MG4K comes with an advanced cooling system that improves heat dissipation by up to 67%, keeping the light safe to handle and maintaining stable performance.
Its IP rating is IP65, which means the MG4K is weather-resistant, so you can confidently shoot outdoors even in challenging conditions. Rain, dust, or heat won’t affect its performance, making it a reliable choice for both studio and field work.
5. Easy and Flexible Control
The MG4K gives you many ways to adjust the light without hassle. You can make quick changes directly on the light, or use DMX and the mobile app. It also supports wireless control through LumenRadio CRMX and can be connected with Ethernet for more setup options.
6. Versatile Mounting and Accessory Ecosystem
The Godox MG4K uses a G-mount system, compatible with a wide range of accessories:
- Reflectors
- Fresnel lenses
- Softboxes
- Projection attachments
This flexibility allows you to create cinematic lighting setups tailored to your creative vision. Whether you need a soft, diffused light for portraits or a focused beam for dramatic shadows, the MG4K adapts to your needs.
Pricing, Availability of the Godox MG4K
The Godox MG4K is priced at around $4,299, with travel kits including cases for $4,499. While it’s an investment, it delivers performance comparable to much larger 4K HMI lights at a fraction of the weight and power consumption.
