When 25% of a household’s electricity bill is due to lighting, it is becoming increasingly more important to keep this number down. One easy way to do this is through which bulbs you buy and where you put them. Energy efficient bulbs are available in a range of fittings from spotlight to fixed and more.

Which bulbs are energy efficient?

In the UK, there are two main types of energy efficient bulbs. These are Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs). The most cost effective option out of these two is the CFL bulb which will save you about £5 per year compared with a traditional incandescent bulb. A traditional incandescent bulb uses a substantial amount of energy to produce light, and therefore much of the energy is lost as heat.

When comparing CFL’s with LED’s, LED’s are more energy efficient. LED’s fit most light fittings around the house including spotlights, dimmers and normal lamp fittings. What makes them more energy efficient is that they require much less wattage than CFL’s and traditional incandescent bulbs. This makes them longer lasting and hence, more energy efficient.


LED’s is short for Light Emitting Dodes. When they were first developed, their main use were for single bulb use in various applications such as pen lights, electronics and more recently, Christmas lights. They are a solid light bulb full of energy efficient power.

LED’s were then transformed into what we know them as now. This is due to the bulbs now using as many as 180 bulbs per cluster rather than just one. The first of these kinds were used for battery powered items including torches and headlamps. However, LED’s are without doubt the best energy efficient lighting as they are available in most common household fittings.

LED’s come in a range of colours. White being the most commonly used, they also come in red, green, blue, white and amber.

When it comes to LED’s, price does matter. To get the most out of your energy efficient lighting it is best to choose the more high quality otherwise they will die out early. Stick to quality retailers rather than cheaper high street.
