There are two situations to consider when installing Mingtai ceiling shadowless lamp.

When installing on the ceiling, it is required to embed four M12×200mm bolts in the ceiling concrete, exposing the ceiling 30mm (diameter 240 on the circumference, 360 degree quarters) in order to install the fixed disc and the fixed seat. The disc can also be hoisted and fixed with round steel bolts not less than 20mm in diameter. Then install the holder.

When installed on a beam, a hoisting chassis with a diameter of not less than 320mm and a thickness of not less than 6mm can be made.
