I’ve just realized that I have missed out on a generation of illumination devices. I still have a fair stock of the now banned incandescent light bulbs, bought cheaply when newspapers were doing stunts against the ban, for those places where a light is needed infrequently but reliably.
I have a much bigger stock of compact fluorescent light bulbs; bought at silly prices like 10p each when the manufacturers were trying to bribe us away from incandescents.
I should have gone on to halogen bulbs, but I didn’t and it’s too late now because the EU will ban them at the end of this month. Bring on the next brilliant idea and I’ll probably ignore that too.
