An optic fiber star ceiling is a lighting installation that creates the illusion of a starry night sky by using small, flexible strands of optic fiber cable. The fiber optic strands are typically bundled together and attached to a light source, such as an LED or halogen bulb, which illuminates the tips of the fibers. The fiber optic strands can be arranged in different patterns and densities to create a customized starry sky effect. The installation is often used in home theaters, bedrooms, and other spaces where a relaxing and immersive environment is desired.
