Energy Calculator

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
