The days might be getting longer and the nights shorter so we are all probably using the lights round our home less. But, lighting is still one of the most significant uses of electricity in our. Lighting offers some of the simplest, cheapest and most cost effective ways to save energy and money at home.
Types of lightbulbs
There are lots of different types of lightbulb that you can buy in the shops. There are different types of technology and each uses different amounts of electricity.
Buying and comparing lightbulbs
In the past we used to compare bulbs by looking at the wattage of the bulbs: the bigger the wattage the bright the bulb. But, due to newer technology it hard to now compare them in this way any more. It is important to compare the brightness of the bulb. Brightness is measured in lumens and is shown on the front of the box. The more lumens a bulb has the brighter it is. A standard 60W traditional incandescent bulb has a brightness of about 700 lumens, so if you wanted to buy a replacement energy efficient bulb you’d want to get a 10W LED bulb. Use the table below to help you.
Typical yearly running cost
You don’t have to wait for your old bulbs to break to replace them. If you still have any traditional bulbs around the house and you replaced them with LED bulbs you’d probably save enough money over a year to cover the costs of buying the replacement bulb.
Let’s have a look at some examples of how much you could save:
If a bulb is used for 4 hours each day for a year, how much does each type of bulb cost? We have assumed a unit of electricity costs 15p/kWh. Savings are compared to replacing a traditional lightbulb.
There are lots of ways to reduce the cost of lighting your home. Check out this calculator to see how much leaving your lights can cost you.
