Dimmable LED bulbs!
Yes, that really does say “dimmable”. And Jha says that this is the “new bulb that will hopefully make the doubters shut up”.
When I moved into my new apartment in 2005, we ended up needing a huge number of 40W reflectors, all on dimmers, which between them consume an insane amount of electricity. What’s more, they need very frequent replacing, which is non-trivial. If I can just replace them with dimmable LEDs which last for 25 years, I will be a very happy person indeed.
