Efficient lighting of Plymouth Devon offer a range of lighting solutions. In most homes, lighting accounts for around 10-15% of the electricity bill. By replacing old and in-efficient light bulbs you can reduce the cost of lighting your home significantly. It is possible to save up to £10 a year by switching one tungsten bulb over to an energy efficient light bulb, such as can be seen below. Realistically the savings per bulb replaced will be closer to £5 each per year. This still means that your investment will be paid off within a year for the majority of our energy efficient light bulbs.
