Ceiling profile for creating a shadow effect.

The geometry of the profile allows for indirect lighting.

This technique provides a perfect gradient of light on the wall without the need for a plastic diffuser.

This profile makes it possible to significantly simplify the installation of the unit and improve the quality of the shadow finish in every sense.

The stock programme includes products painted in white (RAL 9003). Other RAL colours are available on request.

The fixing method is mechanical.

Detailed description:

The C-1 RAL 9003 aluminium profile by ASP Profiles is a professional solution for creating architectural lighting lines in the wall–ceiling junction. Its design allows you to adjust the distance from the wall, forming different types of lighting niches, concealed LED lines, reflected light effects and decorative light contours in modern interiors.

C-1 is used to create soft indirect ceiling perimeter lighting or expressive geometric light accents. The profile is made of 6063-T5 aluminium alloy, ensuring effective heat dissipation for LED strips and long-term system reliability. The standard colour is RAL 9003 (white), with any RAL colour available upon request.
