The cut-out hole is the size opened in the ceiling to install the recessed light fixture, and it differs from the product's full outer dimension.
For example, a light fixture might have a diameter of 10 cm, but the required cut-out hole is smaller so that the frame sits properly on the ceiling.
Therefore, it is essential to check the cut-out hole size before purchasing, especially when replacing an old spotlight or preparing a new ceiling.
Al Zamil Lighting offers recessed units with various sizes and cut-out holes, which helps in choosing the appropriate size for existing installations.
