It’s the same story for basically any part of a home. Faucets, furniture, tubs, windows, doors, floors, lamps, you name it.
What a testament to the manufacturing advances that have made it profitable to cater to every possible taste, budget, and architectural layout. It’s incredible actually.
I just wish there was some way to replace the LEDs on these things when they inevitably die. And, no matter what large number of years or decades are slathered on the box, inevitably at least one LED panel will blow out three to six months after purchase, nominally still in warranty but good luck getting any service under it, I'm sure. If there was, there could be a place for at least some of these in a house, but the amount of crap that you have no choice but to throw out as soon as the LEDs fry is insane.
This is why my "fancy" lighting fixture is an old track (whose proprietary lights died a long time ago) wrapped with an extension cable with 5 standard sockets on it, and some standard light bulbs in it. We dress it up with ribbons and stuff for the seasons. It doesn't look as nice as any of the things in that article, not even the gaudy and tasteless ones, but when a bulb burn out, I put a new one in and get on with life, I don't throw out an entire fan and buy a new one.
I'm old enough to remember when I was promised LEDs would last approximately forever without having to be replaced.

Yep, I remember that when Obama banned most incandescent lights because 'LED lighting is the future and 100 year lifespans blabla'.
Mind you, we used CFLs in the warm season, and incandescent in cold seasons. Incandescents are 100% efficient in cold seasons (heater AND light).
As much as I deign to admit, Trump reversed Obama's ban. And Biden reinstated it. I don't think Trump reversed Biden's reinstatement though. He's been way too busy with wrecking the country for shits and giggles.
But what the LED manufacturers figured out is they could overdrive LEDs and use substandard electronics for driving them. So sure, LEDs are more efficient, but they're the same old burnout cycle that's forced on us.
And we know all of this by the fact that Phillips makes "Dubai Lamps", and you can't buy them at any price. <a href="https://hackaday.com/2021/01/17/leds-from-dubai-the-royal-lights-you-cant-buy/" rel="nofollow">https://hackaday.com/2021/01/17/leds-from-dubai-the-royal-li...
> Worse than natural gas or heating oil, and much worse than a heat pump.
Worse than a heat pump, yes, but very arguable whether NG is more efficient. Arguably, NG powering central electric power generation and then used for resistive would be overall more efficient. Central NG will be more efficient and also there’s substantially less opportunity for NG leakage if piping was reduced.
NG is definitely cheaper (at least in the US), but that’s not really related to efficiency or emissions cost.
I’m not sure that’s easily quantifiable. Yes, thermal efficiency of modern NG furnaces can be ~95% or whatever… but you can also run multi stage heat capturing NG power plants that have very high overall efficiency too. Not 95, but at 60-70%, it’d be a potential wash in terms of emissions if leaks are ~10% (especially considering how much worse unburnt NG is as a leak vs when it’s burnt).
Also, if you’re in the electric ecosystem, swapping to heat pump systems will obviously be lower overall power in basically every scenario, and it gives an easy transition path unlike NG.

Maybe... I've got a NG furnace now and am looking at adding a heat pump, and even with a pretty expansive budget, I'm struggling to make the numbers work on actually removing the furnace entirely vs. doing heat pump + furnace. (And the near-impossibility of upgrading my home service past 100A makes it extra complicated if I want to electrify everything.)
I’m not making the argument for total amortized cost. I’m just talking about per energy unit cost, specifically in terms of CO2 or emissions.
If the evaluation is total lifetime cost to you, using the equipment you currently have almost always wins out. Same with purchasing more efficient hvac and such: the cheapest/lowest efficiency hvac is almost always the most cost effective. That tide could turn with sharp increases in NG or electric prices… but it hasn’t historically been true for many years.

That's resistive heating, which is the most inefficient means of heating. Worse than natural gas or heating oil, and much worse than a heat pump.
