This is a lovely, for fun, thread, (at the moment).
Re the light bulbs. I decided to take down the bedroom ones, and the shades, give them a clean and replace. DH fetched the stepladder, with safety handhold (H&S) and climbed up. He took so long to unscrew one bulb, that I did it myself.
Climb onto bed, wobble a bit, I can’t reach the bulbs from the stepladder, and decided to leave shades in situ and just wipe. Replaced bulbs, one now doesn’t work. Go downstairs and fetch a new one, from my stash of old type ones, climb back onto bed, wobble a lot, and before replacing it, try turning it a bit more. Hurray, we have light. Take replacement bulb back to it’s hiding place.
By the way, the switch is a dimmer, can you get new LED dimmer bulbs?
