composite suspended ceiling / panel / acoustic / luminous
A starlit ceiling can be installed by a drywaller or plasterer.
The most advanced technology offers the best aesthetics (perfect LEDs, transparent, with optical lenses, pined as you like into the entire boards) and reliability (reinforced contacts, anti spark connector, fire resistant, stabilized driver, no toxic smoke). And the ceiling can be repainted, unlike all other technologies.
It can be easily installed by a drywaller/plasterer (like a plasterboard ceiling) or an electrician (like a ceiling light: version with finishing).
Board 18mm or 5cm, your painting, LEDs, drivers, insulated misc, invisible joints.
