Built-in 9W luminaires with special springs for easy and quick installation in the mounting hole. Due to two beam angle options and the ability to adjust the light module horizontally by 355° and vertically by 25°, they can be used for zoning, local and accent lighting, as well as for general lighting. A high color rendering index and low flicker coefficient provide comfortable light that does not distort shades in the interior.

"Those working in V-Ray versions lower than 3.1 should be careful; in the materials section, BRDF is set to Microfaset GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward - whichever is preferable for you."
