The profiles made of acrylic material are about 11 mm wide, permitting the installation between the panes of standard double-glazed windows.

In such an installation their life span is greatly extended thanks to protection from ultraviolet radiation, contamination, and the effects of weather. In addition there is no need for cleaning the profiles.

The intelligent profiles redirect the sunlight independent of the incident angle and illuminate uniformly the ceiling with diffuse light.

LIF Light Guide solves its task only optically without any moving parts. For this reason LIF functions maintenance-free and without running expenses.
