What does "cut-off angle" mean in lighting?

ما معنى فتحة القص في الإنارة؟

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.
