Really? I've never understood the affection for dimming lights. Essentially always I want lights on or off.
But other times I'm just wanting to cozy up to the fireplace with a book and some light music and a dram of whiskey late in the evening. I don't need the room to be super bright, so I might just have the lights over the fireplace on set very dimly.
Same goes with the kitchen. When I'm actively cooking a meal, I want it very bright. But I don't always need it that bright, sometimes I just want it a bit more ambient in its lighting.
Or the dining room. Sometimes I use that space for projects as it has the large table, and I'll want it as bright as possible. But other times, I could probably stand to have it at about 75% of its brightness as we're just sitting around together having a meal, and with my home layout its a bit of a central space so its nice having it at like 20% brightness to act as a bit of a night light as people go through the house.
But, dimmable bulbs are also an indicator of quality. Someone cared enough to make sure it worked in that situation, so there's evidence that someone was caring during the design.
Maybe. It could also be to avoid the situation in which the average consumer just picks up the cheapest bulb and, when he gets it home and it is flaky when used with the dimmer, returns it to the store.
Or maybe it's a low quality way of ticking a feature that a customer has been told to look for regardless of whether it is relevant to his situation.
It also is a tad hyperbolic to include non-dimmable bulbs in the pantheon of things to make homeowners lose their minds.
I think the big surprise for most people would be that many LED bulbs are not dimmable, as that hasn’t been something they had to worry about with older bulbs (it was also an issue with CFLs, but people avoided them because of the harsh color)
I'm really miserable in a too-bright room. I have some sensory processing issues which contributes a lot to this admittedly, but when I talk about it with people who don't they often understand it immediately or admit to experiencing the same thing, though to a smaller extent.
It's about choice. I have several dozen LED can lights in my house producing 1600 lumens each. Sometimes I want every bit of that power, but I also like being able to turn them down a bit in the evening when I don't need it.
You could hire a lighting consultant, then buy expensive bespoke bulbs so that having them at 100% is the right choice, or you could spend an extra ~ $50 per room for a dimmer.
