Consumption : 36 W 14 W
Luminosity @ 1m : 230 Lux 300 Lux
Lifespan: ~2 years ~10 years
Energy savings : 96 kW.h/yr/bus shelter
 Equaling a reduction of 22 metric tons CO2* for a city equipped with 500 bus shelters.

 

These calculations are based on an average lighting duration of 12h per day.

* 1kW.h = 0,46 kg CO2 (european average)
