Overview
The Godox ML-B4 Magnetic Barndoor Set for ML80Bi and ML150Bi LED lights is a practical accessory that enhances beam shaping and light control when used in conjunction with the ML-Z Zoom Lens Reflector. This set includes four magnetic leaves that attach quickly and securely around the front of the reflector, allowing users to block, crop, and direct light with precision. By restricting spill light and shaping the beam path, these barn doors help achieve more defined lighting effects — ideal for adding rim light, focusing on specific subjects, or preventing unwanted illumination on background elements.
The magnetic design ensures fast, tool-free installation and removal, empowering creators to adjust lighting on the fly without interrupting workflow. This is especially beneficial in dynamic production environments where lighting needs may change from shot to shot. The barndoor leaves are made from durable materials suitable for frequent use, and their compact size means they can be carried easily with other accessories in a lighting kit or travel bag.
Using barndoors expands lighting control beyond what is possible with soft diffusion or fixed reflectors alone. For example, photographers and videographers can use the ML-B4 set to sculpt key light edges, create dramatic contrast, or isolate backgrounds from foreground subjects. They can also fine-tune the beam for product work, interviews, or narrative scenes where thoughtful light shaping improves mood and depth.
The ML-B4 Magnetic Barndoor Set integrates seamlessly into the modular Godox accessory ecosystem, adding professional-grade beam control to the versatility of ML-series LED lights. Whether in controlled studios or on location, this set provides intuitive, effective control over light direction and spill.
