Dublin business group DublinTown has started putting up the city's Christmas lights so they are ready for switching on by the middle of November.

25 streets will have energy efficient lighting for the festive season this year.

The Christmas lights are by far the biggest task that DublinTown undertakes for its business members and the people of Dublin.

It takes 30 people working through the night, over four weeks and over 200 hours to completely put up all the lights.

Each single bulb and fixture are tested by lighting contractors in advance of the big switch on.

DublinTown said the presence of Christmas lights gives a sense of joy to the city and adds to the buzz and excitement as Christmas approaches, attracting thousands of people.

In line with previous years there will be no public event this year, but the lights will be officially switched on in November and light up the city each day until early January.

DublinTown is the city centre's Business Improvement District, which stretches from Parnell Street to St Stephen's Green.
