Heating your house with lightbulbs, bitcoin miner gear, class A audio amplifiers, or anything really is all the same. Wasting energy by converting it to heat -- there is no bad way to do it
I am always amused by expensive 'high efficiency' electric heaters. They are all 15 Amps, converted to heat resistively, convection or radiant . There is no such thing as an inefficient heater. Where would rhe waste go, heat?

Ha yes. Technically correct, they are all 100% efficient at converting electricity into heat. Putting square footage on them always annoyed me too. There are no product differentiators and it drives marketing crazy.

Some LED bulbs have better light quality than others but you might have to pay more. I have bulbs from my previous house (so they must be at least 13 years old) that are still going strong. Other "start up" brands from that time didn't last long despite being expensive by today's standards. Cree was one of those brands.
Sadly, I still have compact flourescent bulbs that I refuse to throw away until they burn out. Luckily my city has a recycling center for those things.
I knew a very conservative guy who's very conservative dad bought a bunch of incandescent bulbs back in the day out of fear they would be banned by the evil powers that be. This guy was shocked to find out how much you can actually save over time by going LED. And no, I don't think he was a connoisseur of quality lighting.
The blue LED is one of the greatest inventions of the modern age, IMO.

Yeah my early device failure was a Cree. Blue LED was a major leap ahead technologically. And the guy who worked for years to invent it (Shuji Nakamura) got a pittance. He got a 404 patent worth less than $200 and his employer said he got just compensation, earning approximately $56k per year for 11 years of employment. He sued and got $8 million, just enough to cover the legal expenses. The lesson here is to never try and never ever apply yourself.

A decade+ ago I bought a few specialty full-spectrum 100W didymium bulbs which have an amazing light. It's like a happy sunny day when you were a kid.
Those are the ones I screw in in the winter, although the light quality is well worth the $20 a month or whatever it costs, really. And it helos my partner's SAD

ironic, indeed.
we placed some mirrors on the field to reflect sunlight into the living room, which works fantastic and feels natural. except that after every cup of tee i have to go out and move the mirrors a bit :)

Paraphrased from a personal note I rediscovered. "Today we have LEDs and fluorescent lights, which are extremely energy-efficient. They can even be powered directly from solar panels. We use the natural power of light rays from the Sun to create artificial light. Ironic, isn't it?"
