How much recess depth do I need?

Most JCL recessed downlight fittings require a ceiling recess depth of 120mm minimum. This allows room for the movement of directional fittings, and allows a good airspace around the back of the fitting for air ventilation and fireboxing if necessary and allows for easy installation of a transformer. Our collection of wall and floor recessed fittings have individual recess depth requirements – please refer to the specific detailed product information available.
