C20-R G2

Direct light, low glare


When is a room professionally illuminated? We think it’s when the lighting supports you in carrying out the tasks that the room is designed for. Whether it’s children’s exploration of building blocks or an adult interpreting the facial expression of a client, proper illumination can make a big difference.  

Visually beneficial light 
Glamox C20-R Generation 2 is a recessed luminary developed to give you light that is both comfortable and visually beneficial. This is achieved by using double parabolic softlight louvers that secures good shading and high efficiency. The louvers are especially developed for LED, and the semi diffusing material creates a soft transition from light to dark and softer shade.  

Why louvres?  
Glamox has been working with louvers since the beginning of 1980s and although we in recent years have developed products with different types of optics, we are certain that louvers will never disappear. The design has of course been modernized and refined over the years, but the basic principle stays the same. Louvre are extremely efficient way to direct the light exactly where you want it and at the same time keep glare well under control.  

For kindergartens, schools and offices 
C20-R is well suited for applications that involve small children like kindergartens and primary schools. Up until the age of 7 it is important to have more direct light to increase the depth view. The louvers in C20-R offers direct light – with low glare.
The excellent glare control (UGR 19) and high energy efficiency also makes C20-R a good choice for offices.  

Light management 
Modern schools and offices are often equipped with a light management system. C20-R is of course available with presence and daylight sensors that allows it to be a part of a LMS solution.  

Low maintenance high flexibility 
C20-R has a flexible design that can accommodate most ceiling systems. A smart external driver box ensures easy mounting and maintenance since everything can be done without opening the luminaire. The luminaire is available in three different sizes and can be supplied with 1-4 louvers depending on size. C20-R is also available with emergency light.
