5 advantages of SL27100 LED linear lighting

Balanced light

The SL27100 LED linear lighting uses an up-and-down luminous pattern to even out the light in the space and reduce the contrast between light and dark in the space, which is very good for eye health and allows for constant, focused, and productive work.

Outstanding energy efficiency

The SL27100 LED linear light uses high-quality LED drivers with a PF ≥ 0.9 and has more energy use than conventional types of lighting, making it the luminaire of choice for sustainable lighting solutions.

Long life

The SL27100 linear lighting with LED chips has a very long life span, typically up to 50,000 hours as tested by kosoom engineers, which means that the maintenance and replacement of LED linear lighting fixtures is greatly reduced, reducing maintenance costs and inconvenience.


The SL27100 LED linear lighting is green, both the chips in the luminaire and the various accessories such as the housing do not contain harmful substances such as mercury, making it easier to recycle even at the end of its life without impacting on the environment.
