What’s that light doing then having to be on all day in winter? I can perhaps understand a need when it’s dark, but daytime is a puzzle.We only have one incandescent light in the home and that is 100w and is for a lamp as I have yet to come across a reasonably priced LED lamp that will give the same illumination as our 100w lamp which is switched on most of the day and evening during the winter. It also seems to last longer than any £8 LED bulb.
