Savings per year: 15,67 euros / year

 

Model calculation 22)

Savings per year when replacing eight 58 watts 150cm neon tubes (for example office lighting) with eight 25 watts 150cm led tubes

Power consumption with conventional neon tubes: 1694 kWh / year
Power consumption with new led tubes: 730 kWh / year

Basis of calculation:

1) 365 days/year, 4 power-on hours per day, electricity rate: 0,29€/kWh gross

2) 365 days/year, 10 power-on hours per day, electricity rate: 0,29€/kWh gross
