Sorry for starting multiple threads, but ...
Yep, I'm having a day. The bedroom light burned out after several years of heavy use. Luckily (or so I thought) the fixture is right over my bed, and that helped me pop it open. YIKES! What the hell was I looking at? There was no bulb and whatever was up there was all hardwired. There is a box that I assume must be some form of LED light (just a cube about one inch on a side and half an inch or so in depth), but I don't see any way to change it without tools and probably needing to find the right circuit breaker and I haven't seen anything like it in any of the local shops so it probably needs a specialized supplier. No thanks, it was easier to buy a lamp.
Lightbulbs. They used to be a simple choice, either an incandescent bulb or a fluorescent tube. If you were daring you might even consider a colored bulb or a black light. Now though, incandescent bulbs are a thing of the past, there are swirly fluorescent bulbs to take their place, but those are getting upstaged by LEDs. They're one of those things that don't really demand a lot of thought, until something goes wrong or you need to fit a special need.
So, what do you guys prefer? Do you use any kind of novelty bulbs? Do you miss incandescent bulbs? Are you just wearing a candle on your head and prone to getting mugged?
