therefor saving of £611 so far.
and more importantly just over 1 tonne of CO² saved
the LEDs were £9 each back in Jan 2014, think they are about £3 each now.
I have probably saved even more since swapping to LED's. I bought around 20x 3.5w quality LED's at BHS store closure at 50p each. They put out a surprising amount of light and I used them as my general replacement around the house, where a lot of light wasn't essential, backed up by more powerful CFL lighting sources for when more was needed, with the addition of turning lights off when not needed.
I still have two tungsten lamps, one lighting the under stair cupboard, the second lighting the back door foyer area - neither are normally used. Three florescent tubes in my loft workshop, another lighting the utility, then several modular florescent fittings lighting my garage and workshop.
