Energy efficient lighting has two major benefits – it reduces the impact of our homes and businesses on the environment, and reduces our home energy costs.
Lighting is a big source of energy consumption and in many homes, lighting makes up about 10-15% of the electricity bills. The carbon dioxide created by the generation of this electricity is harmful to the planet so by switching to energy efficient light bulbs, the carbon emission is reduced along with the electricity bills.
The incandescent light bulb traditionally used to provide light in homes and offices are very inefficient and on average convert only 5% of the energy they receive into light. Similarly, fluorescent tubes used in commercial buildings tend to be inefficient also.
Various options exist for energy efficient lighting, including Compact Fluorescent Lights or CFLs. These are mini versions of the full-sized fluorescents and fit standard sockets in the home, giving off lighting that resembles that of incandescent light bulbs. Far more efficient and long-lasting compared to traditional bulbs, CFLs reduce lighting costs too.
LED, or Light Emitting Diode, light bulbs are gaining in popularity because of their small size and durable nature combined with efficiency. LEDs can replace both halogen and traditional bulbs, and manufacturers now “cluster” the small bulbs and include diffuser lenses giving a better spread of light. These energy efficient light bulbs fit most household lighting fixtures and last up to 10 times as long as CFLs and significantly longer than traditional incandescent bulbs. LEDs are solid too, making them less susceptible to knocks and breakages; and they remain cool with no heat build-up.
As energy efficient light bulbs use less energy and are a lot more efficient, energy bills for the home and office can be reduced by as much as 80%. A good investment, LED bulbs last a long time and do not need to be replaced often, saving money for the individual and also maintenance costs for companies as the bulbs need to be changed less frequently.
