Energy Reduction

When replacing street lighting, the adoption of LED light sources results in white light. This allows substantial improvements in the quality of lighting and considerable reductions in energy consumption.

Stela has been proven in practice to save even more substantial amounts of energy due to its highly efficient and precise Directa lens technology system, which eliminates waste light. Existing installations have shown energy reductions ranging from 42% to 78%.
