Saving energy on lighting

The cost of lighting

Lighting is one of those essential things you need in your house, but that doesn’t mean it has to cost the earth. If you still have old fashioned incandescent light bulbs in your house, you really should replace them as soon as possible with new LED lights. In the old days lighting was fairly simple, as you had 3 main choices of light bulb, 100 watt, 60 watt and 40 watt. But now you have all sorts of wattages available in LED, so it can be hard to know what is right for your home.
