R&N Solar can help consult, design, and install with your ideas and dreams in living a greener lifestyle

The figures below are of the E-house lighting, which has been fitted with energy efficient CFL and LED lights, the calculations at the bottom are the daily average usage in Kilowatt hours and carbon dioxide per kilogram emission.

CFL & LED Lighting

1. 40*CFL Down lights throughout household.
2. 10*CFL Outside lights.
3. 10*CFL Outside lights.

Electricity consumption

1. 40*11 Watts per fitting = 440 watts
2. 10*13 Watts per lamp = 130 Watts
3. 6*20 Watt Per lamp = 120 Watts

Daily consumption

1. Lighting Total = 690 Watts
2. Average daily usage 5 Hrs
3. Daily KWH Consumption = 3.45 KW/Hrs
4. C02 Consumption Daily = 3.90Kg/C02

Conventional Halogen lights

The figures are based on the conventional house that would have halogen down lights installed throughout the house instead of the new CFL lights, the comparison in electricity and C02 emissions can be clearly seen.

Electricity Consumption

1. 40*60 Watts per fitting = 2400 watts
2. 10*50 Watts per lamp = 500 Watts
3. 6*150 Watt Per lamp = 900 Watts

Daily Consumption

1. Lighting Total = 3800 Watts
2. Average daily usage 5 Hrs
3. Daily KWH Consumption = 19 KW/Hrs
4. C02 Consumption Daily = 21.51Kg/C02
