LIGHTBULBS

Under EU Regulation inefficient incandescent light bulbs are being phased out throughout Europe with effect from the 1st September 2009 and are being replaced by more energy efficient alternatives such as compact fluorescent lamps (CFL's) and light-emitting diodes (LED's).

While CFL,s are the most common in Ireland, LED's are starting to revolutionise the whole lighting concept throughout Europe and are making their way into Ireland. The equivalent wattage (power) for CFL's to Incandescent standard bulbs is shown below in Table 2.. This is quite good and saves you on average 80% on your lighting bills. LED's however are better again and can save you on average 95% on your lighting bills. But most homes will still require a balance between CFL's and LED's as certain situations will often favour one over the other i.e. light warmth, light strength, room position, frequency of use etc. There are energy efficient bulbs for all types of fitting. The most common types are shown below in Table 1and are available as CFL,s and LED's.

Some people have the idea that because the price of the energy efficient bulbs are greater than that of the Incandescent ones, its will work out cheaper to keep using the standard old bulbs for as long as they are available. This so not the case and please note the examples below which are factual calculations.  

Bulb Type. Time switched on. Initial cost. Life duration. Cost to run per annum. Saving in first year. Saving in year two.

Total saving over 10 yrs

Standard 75W B22d 5 Hrs/day €0.50 1-2 yrs €21.91 €0.00 €0.00 €0.00
CFL 13W (Equ. 75W) 5 Hrs/day €6.00 6-8 yrs €3.79 €12.62 €18.62 €180.20
LED 4W (Equ. 75W) 5 Hrs/day €12 10 yrs plus €1.17 €9.24 €21.24 €212.40

These savings are for just one bulb. Multiply these saving by the number of similar bulbs in your house and/or business.

  

Room with 6 no. spots. Time switched on. Initial cost. Life duration. Cost to run per annum. Saving in first year. Saving in year two.

Total saving over 10 yrs

Standard 50W GU10 5 Hrs/day €6.00 1-2 yrs €87.59 €0.00 €0.00 €0.00
CFL 11W (Equ. 50W) 5 Hrs/day €36.00 4-5 yrs €19.27 €38.32 €74.32 €707.20
LED 3W (Equ. 50W) 5 Hrs/day €72.00 10 yrs plus €5.25 €16.34 €88.34 €883.40

These savings are for just one room. Multiply these saving by the number of similar rooms in your house and/or business.

The above examples show what savings are to be made and include the initial investment cost. They show that your initial investment will be paid back (and more) within a year. Then its substantial saving every year after that.

A typical home will save around €200 a year by just changing to energy efficient light bulbs for an initial cost of around €150.

There are other products that will help reduce your lighting consumption (cost) even further, such as Dimmers, Motion Sensors etc, allowing you to only use what level of lighting you require.
