After years of watching energy cost rise we’ve insulated the house, installed low energy devices and now it’s time to look at the lighting.
The 50w Halogen lamps are replaced with 5w LED lamps
Replacing 1 Halogen lamp with 1 LED lamp saves £13 a year, see below for details.
It is very important to make sure that the replacements are selected and installed correctly otherwise the energy and maintenance savings may not be as expected, see note 3.
Average daily use of 5 hours per day, 7 days a week, 52 weeks a year.
