School louvre luminaire have been used for a very long time and have not changed with the advent of LED sources. MODUS is able to offer louvre LED lights with modern chips. The advantage of using louvre lights is undoubtedly low glare. LLL luminaires are the direct successor of LLX luminaires, which have been used extensively in classrooms. LLL luminaires are developed so that the luminous flux is the same as the previous version of LLX on T8 lamps. Lamps LLL can therefore be used as a 1: 1 replacement.
