Light Pollution

LED street lights have many benefits for residents, pedestrians, cyclists and motorists.

Stela’s unique design means that light pollution is kept to a minimum. This is achieved through the careful design of the lens system that only puts light where it is needed and avoids the scattering of light seen in many traditional luminaires.

Light that is emitted above the horizontal of the luminaire is called upward light and is primarily responsible for light pollution. Stela virtually eliminates light pollution by placing 99.5% of available light onto the ground.

Stela’s design guarantees more accurate and uniform light distribution, which eliminates light pollution.
