Newer construction doesn't install proper fixtures anymore. No more user-replaceable bulbs. Everything is screwed directly into the box and you have to do a minor electrical job on every unit you want to replace.
I too strongly dislike the lack of replaceable bulbs in newer LED fixtures. It's outrageous how many things in modern construction shave a few cents here and there to get the initial cost down, and the long term costs are enormous. Once the house is sold it's someone else's problem and that mentality is disgusting.
I think I solved this in my old house. BR40 bulbs. I don't recall the specific vendor but they were very expensive.
The amount of work it takes to get up to the fixture is most of the effort, so I can lean both ways on this one.
Surely someone can devise an internal circuit to disable some combination of the LEDs to do proper dimming without relying on PWM.
The luxury days of installing an incandescent bulb that lasts for ten years are gone, lucky to get six months out of "contractor grade" LED products and consumer devices usually don't make it much over a year.
Sure, burns a little less coal, but its not like LED manufacture and shipping is as environmentally friendly as beewax candle production LOL. Overall we're probably worse off as a civilization with LED lighting.
I'm always surprised to read such comments, incandescent bulbs definitely burned out regularly, and the LEDs we have now are more or less as durable in my experience.
I still have a few CFL bulbs that are more than 10 years old (that I keep because their slow warm-up is actually desirable in some cases) and my Ikea LED bulbs are all between five and three years old. One of them (out of 12 I think?) did fail last year, it was four years old.
