ML-B4
Magnetic Barndoors for Precise Beam Control
The Godox ML-B4 Magnetic Barndoor is a compact light shaping tool for the Godox ML-series bi-colour LEDs. With four adjustable leaves and a magnetic design, it lets you flag spill, narrow the beam, and control where your light lands. It is a perfect add-on for creators who want more control from the Godox ML80Bi or Godox ML150Bi without adding bulk to the kit.

Control Spill and Keep Your Set Clean
Barndoors are one of the simplest ways to make your lighting look more intentional. Use the ML-B4 to cut light off the background, prevent flare, or create a tighter highlight on a subject. It is especially useful in small rooms where light bounces everywhere.
Fast Magnetic Workflow
The ML-B4 is built for quick setup. Snap it on when you need control, remove it when you want open coverage, and keep your ML-series setup streamlined for mobile production.
Made for the ML80Bi and ML150Bi System
The ML-B4 is designed to work with the ML-series accessory ecosystem. For mounting, it requires the ML-Z lens reflector on the light, then the barndoor attaches magnetically for secure, repeatable positioning. This reflector is the one normally included with the ML80 and ML150.

FAQ
Which lights is the ML-B4 compatible with?
The ML-B4 is designed specifically for the Godox ML80Bi and Godox ML150Bi.
Do I need anything else to mount the ML-B4?
Yes. The ML-B4 requires the ML-Z lens reflector on the light. The barndoor then attaches magnetically to the reflector for beam control.
What does a barndoor help with?
Barndoors help you control spill and shape the beam. They are great for keeping light off backgrounds, creating tighter highlights, and preventing unwanted light from hitting parts of the scene.
Is this useful for small studios and home setups?
Yes. In smaller rooms, light can bounce everywhere. The ML-B4 helps keep your lighting clean and controlled, especially for backgrounds, hair light, and accent lighting.
