Low Energy Lighting

Did you know that lighting accounts for 8% of a typical household’s energy bill.

There are many ways to save energy and save money on your electricity bill but one of the easiest and most cost effective ways to do this is to switch over to low energy lighting.

So what difference does it really make?

Well let’s look at one example.  If you run one 50W halogen bulb for 5 hours per day the annual running cost would be approx. £12.78 (assuming a current energy cost of 14p per unit). 

If you replaced this with a 5W LED bulb, the annual running cost would be £1.28.  So that’s a saving of £11.50/year on just one fitting.  How many 50W lamps do you have in your home?

Lamp types

Traditional light fittings use incandescent or GLS light bulbs and most down lights/spot lights use halogen bulbs. 

However, technology is moving on at pace and today’s low energy and LED bulbs are very efficient and quick to start up (unlike some of the earlier low energy bulbs).

Here’s our quick guide to the different types of standard light bulbs available:

  Type of Lamp Average Life
   Eco Halogen Saves on average up to 30% of energy compared to traditional incandescent lamps.  42W roughly equivalent to 60W. 2,000 hrs
  Compact Fluorescents (CFLs) Saves on average up to 80% of energy compared to traditional incandescent lamps.  11W roughly equivalent to 60W. 10,000 hrs
  LED (Light Emitting Diode) Saves on average up to 85% of energy compared to traditional incandescent lamps.  10W is roughly equivalent to 60W. 25,000 hrs

Most of the traditional shapes of bulb are now available in the 3 main types of lamp outlined above: Standard/GLS, Candle, Golf Ball.

There are many other types of lamps used in a wide variety of fittings but probably the most common down lights and spot lights take a GU10 or MR16 lamp.  Retrofit Compact Fluorescent and LED lamps are widely available and can simply be swapped over in your existing fitting.  Dimmable and non-dimmable versions are also available.  However, not all fittings will take LED lamps due to a difference in transformer type within the fitting. 

If you would like to swap over to low energy lighting but don’t know where to start, why not book one of our free lighting surveys.  An experienced electrician will visit your property to assess your current lighting and recommend low energy options.  We will then provide a written quotation of the cost to make the changes for you.  Included with our quotation will be a summary of the changes and the energy/cost savings you can expect to make.
