The new bulbs last forever though, Right back at the beginning of these I was sent a couple by my electricity suppliers (now this was definitely whilst I was still in the family house, from which I moved in 2003. I put that one in the bedroom and took it with me to my new bedroom when I moved.
Still going strong and it has come with me to this flat. Will probably outlast me.
I have one of Ikea units in my hallway which is just a series of square areas, in which you can fit drawers, cupboards etc. The bottom four has wicket baskets and one of these has loads of light bulbs. Got rid of the older type ones during my clutter clearance before I moved. So just modern long-lasting economical on electricity ones now.
Couple of days after I moved, I had my 6 foot 4 inch tall g.son change a lampshade in a ceiling fitting for me,. Clever lad, he has four A levels in science and maths, but had no idea how light bulbs worked. So, there was I having to talk him through taking out the bayonet bulb = he said he did not know these existed, thought all light bulbs were screw ones. Then telling how to, safely, take down the old shade and put up the new one, and then put in a modern bayonet light bulb in the fitting.
