Help put the stars back in the sky……
On average about 30% of your electricity bill is for lighting, so leaving lights on unnecessarily can be a real waste of money and energy – reducing the use of a 60-watt bulb by just one hour a day will save 22,000 watts of electricity over a year!
Outdoor halogen security lights are usually fitted with at least a 150-watt bulb, and often as high as 500-watts. They also tend to light up too easily and stay on for too long, making them both expensive to run and annoying for neighbours.
The Campaign to Protect Rural England (CPRE) and the British Astronomical Association have been campaigning to reduce light pollution of the skies at night. You could help them ‘put the stars back into the sky’ and reduce your electricity bill at the same time by replacing the bulb with a dimmer one. Or it’s possible now to buy low energy units with power saving bulbs – some are even solar powered (available from Nigel’s Eco Store).
Angling the light downwards to illuminate the immediate area better makes more efficient use of the unit and causes less light pollution.
