The GVM 1200B AIO is a professional LED video light designed for photography and videography. Before use, ensure the ambient temperature is between -20°C and 45°C. Always remove the protective cover before turning on the light. Do not stare directly into the light source. The device requires a stable power supply and should be mounted securely on a light stand.
Product Overview
This light features COB LED technology with a CRI of 97+ and a color temperature range of 2700K to 6800K. It supports three lighting modes: CCT, Source Matching, and Effects. Control is available via the onboard panel, GVM Mesh Bluetooth App, or external DMX/CRMX controllers (accessories sold separately).
Installation
Stand Mounting: Slide the 5/8" receiver over the spigot on the light stand. Tighten the securing knob on the yoke to ensure the light does not wobble. Adjust the tilt angle by loosening the angle locking handle on the side of the yoke.
