Energy Efficient LED vs. Traditional Incandescent Light Bulb

Energy Calculator Example
Current Lamp Wattage 60 watt
No. of hours on per day 10
x 365 days 219,000
** x 12p kWh pence per hour cost total/1000 (£26.28 per year)
* Low Energy Wattage 5 watt
No. of hours on per day eg.10
x 365 days 18,250
** x 12p kWh pence per hour cost total/1000 (£2.19 per year)
Current price per annum £26.28
New price per annum £2.19
Annual saving per lamp £24.09

* based on 5w low energy LED lamp and a 60w traditional incandescent household lamp

** based on standard energy charge 12p kWh
