The inner 66mm recessed LED channel profile is designed for lighting solutions that are brilliant and all-in-one. It has a great height of 18mm and a big inner width of 66mm, so it can store a lot of multi-row LED strips and give off more light.
This wide, shallow aluminum channel with flanges is meant to be put together without any seams. As shown in the installation diagram, it is safely attached to ceilings with spring supports. Adding a PC diffuser cover to the profile will give you a wider, softer lighting effect that looks more professional by cutting down on harsh shadows and hot spots.
