Ya know, I usually don’t “like” random meme images in discussion threads, but I’ve texted that one to enough people that I had to come back and click it.

I suspect that is often the side effect of the fact that most construction isn’t specced by the future long term occupant:
If you were building your own house to spend 20 years in you’d be silly not to take the long view(unless absolutely at the edge of your ability to pay now and save over time, that’s unfortunate but understandable). If you are just slapping together a realtor-ready burbclave cluster as quickly as possible to be ready for resale; or moving a few spit-and-drywall ‘build to suit’ walls around for some cube farm’s new lease your incentives are different.

That all makes sense, but what I’m reacting to is infill or teardown building in my established neighborhood, not fungal housing. Most of it probably is contracted by the owner, not built on spec for later sale (judging by lack of “for sale” signs). Which then has me scratching my head. The marginal cost for better insulation is pretty small in the overall scheme of the cost of a construction project.

What we have here that I described above " tall slim houses with a lot of surface area per enclosed volume, six inch fibreglass batts in the walls… and still nat gas heating" is infill housing. The city loves it;higher tax revenues with little to no increase in infrastructure cost. Ten years ago it might have been a large duplex with a shared wall ( thus lower heating costs ) now it’s these quickly and poorly constructed half lot infills.
Rough-service bulbs are called for in that application. That makes me wonder, are LED bulbs suitable for environments subject to vibration or physical shock? There’s more inside them than a few pieces of wire, in any case.

Not that there are any left here to invest in.

all LED lights have spectrum issues, since the actual semiconductor comes from the same handful of (stupendously advanced and expensive) factories whether it’s a cheap lamp or a more expensive one. The difference is in quality control and design competence – cheap lamps are more likely to fail due to shod, or use a poorly-chosen LED, e.g. with a higher color temperature than most people want in their home, or using an RGB LED as a white light source.
With any modern white LED, the light is absolutely fine for almost all purposes and no one can tell the difference. However, if you’re, say, a painter or printmaker, LEDs can produce some significant odd effects when comparing certain specific colors due to the presence of small, sharp discontinuities in their spectrum.
Needless to say, a cretinous goiter like Turmp could no more access that level of cognitive discrimination than a flatworm can grasp general relativity. Roadkill has more exacting lighting requirements. If he took a magazine quiz about what kind of lighting would work best for him, the answer would be “X-ray laser”.

Unfortunately that’s one of those ‘it depends’ questions.
Rough service incandescents are inherently less good at their jobs than standard ones, since mechanical durability is an enemy of keeping the filament hot by minimizing thermal conduction.
LED bulbs vary vastly in durability; but in large part because of the support circuitry that drives the LEDs, with some contribution from the quality of the LEDs and phosphor(if white).
A high quality LED driver circuit, especially if potted. would be both more efficient than a cheapie and likely to be extremely durable; while a ‘printing the UL logo on the box is compliance, right?’ issue unit might have components cracking off the board inside a week.

Hey, thanks! I have an opener I haven’t managed to get working with LEDs in it, it seems they emit too much RFI. The failure mode is that if an LED is in it, you can operate it using the remote once, but then you have to wait a few minutes (until the light shuts off) until you can operate it again. So, I’ve had CFLs in it; it is a terrible location for CFLs since it gets cold in the winter, which makes the CFLs get dim, and they never get a chance to warm up. Your expedient hack would probably do the trick for me, just move the source of RFI a little farther from the opener and Bob will undoubtedly be my uncle.

There is some small bit of truth (though not much) in what he says. ALL light bulbs I have a spectrum that is much more narrow then sunlight. Which is the color of light that your eyes work best with. The way to make that better is to use, when you have several light bulbs on in the room, ones with different color temperatures.
Yet another example of how he is reflexively reactionary. Just about anything new is wrong. Grandpa Simpson is now president.

I try to get 2700° K LED bulbs. They seem to give a more natural (i.e., less blue) light.

When the TV was the only source of 6500K light in the house, it became particularly hypnotic
Now people can light their real-world environments the same way if they want
I guess it’s good to have the choice

Well I believe in museums they have actual color balanced lighting to bring out the colors as close to sunlight as one can. Most homes, though, have some natural light.
Everyone preferred painting with sunlight in the room, as you colors look the best, but of course if you were staying up painting late at night you dealt with what you had.
Low-pressure sodiums are my FAVORITE. Though I see them more as intensely orange than pink.

There are different ways to make “orange” light. Some of them offer us the opportunity to distinguish red, yellow and green objects. Others actually make everything look orange, or brown, or black. It’s one way we can tell the difference between incandescent and LED Halloween lights, for instance.
