Product Information
Full details
The Godox KNOWLED M300D is a high-output 300W daylight-balanced LED designed for professional cinematographers, commercial photographers, and studio content creators who require intense, reliable illumination. Its primary strength lies in its exceptional brightness and color accuracy, though it is important to note that its heavy-duty construction and external control box design are best suited for permanent studio setups or organized production environments rather than fast-paced, run-and-gun shooting.

Troubleshooting
Light unit is not turning on despite power connection
Verify the connection between the external control box and the lamp head is secure and that the locking mechanism is clicked into place.
Godox Light APP cannot find the device
Ensure Bluetooth is enabled on your phone and the M300D is in pairing mode. Ensure no other devices are currently overriding the connection.

Setup, Compatibility & Care
To set up the M300D, connect the power cable to the external control box and use the included multi-pin cable to link the controller to the lamp head. Ensure the locking collar on the cable is fully secured to prevent signal loss. The light is compatible with any standard Bowens-mount modifier. To attach a light shaper, align the pins on the modifier with the Bowens receiver, rotate clockwise until it clicks into place, and tighten the tension screw.
For care, always keep the protective cover on the COB glass dome when not in use to prevent damage to the LEDs. Avoid touching the glass surface with bare fingers, as oils can cause uneven heating. Store the control box and head in a dry, ventilated area, and periodically check the fan intake vents for dust buildup to maintain efficient cooling.
