In general, there are 4 types of installation options for 120×30 LED panels:
Embedded in Armstrong plaster (without accessories), Embedded in translational Moroccan plaster, Exposed and suspended (the last three require kits). Each type of installation is efficient and aesthetically pleasing, but each has its own advantages depending on where the LED panels will be installed.
On the exterior side, a recessed panel is thinner (around 1 cm), while the surface-mounted LED panel is thicker (around 5 cm), screwed using dowels to the ceiling.
Surface or suspended mounting is perfect for mounting LED panels in a location without a false ceiling (either Armstrong or Moroccan translational), for example a plaster ceiling.
