IDK if you've noticed but we are all lighting our house with bulbs that use 1/10th the amount of electricity as incandescents did. I like the color spectrum of a real lightbulb better, too, but not enough to pay 10x in power. I make up for it by using all kinds of random bulbs all over the place so that the aggregate light in the room fills more of the spectrum than if I coordinated them all to be the same.
The really awesome thing about the 1/10 power consumption is that the existing circuits/wiring/sockets now suddenly support 10x the light without burning down your house. I'm a sucker for well lit space and these lights are just heaven for me.
Did you try using high CRI LEDs with color remperature of 2700K–3000K? When I switched from halogen to LED I did just that and the difference is not noticeable, you'll have the same yellowish tint and very natural looking colours. Even with expensive bulbs, extra longevity covers for higher cost.
2700 is really cool. To the GP, if you're looking for something more like daylight but not noticeably yellow, try 3600k or thereabouts.
The actual temperature of the sun is over 5000k (yes, the k in lightbulb temperature corresponds to the Kelvin scale of temperature) but after being scattered by our atmosphere it appears cooler. And where did all that extra light go? It was scattered around, making the sky blue!
3700-4500 is my range I like these days

The problem is we went from a market that consisted of cheapo/good bulbs at various brightness levels to a market where Walmart and Home Depot have like 60 linear feet of bulbs.
There’s no standards and people are clueless and confused. There are awesome LEDs, but more often you see have harsh, terrible light.

Yeah I know. I love it in my house.
On the industrial side, sodium vs LED is a much closer comparison generally than LED vs incandescent. LEDs kinda suck for high bay applications.
Depending on where you live the heating might be nice.
In the US people use roughly 10 000 kwh per year.
Say we have a 40 watt bulb, say it burns on average 5 hours per day or 200 wh. In 365 days that would be 72 kwh which at 16 cents per kwh is $11.52 or 0.73% of the annual power consumption.
Say one uses 5 light bulbs. Something around $57.60. Say leds use only 25% of the power = $14.40 for $43.2 saved.
Well over 10 cents per day.
What are you going to spend your 10 cents on? lol
How many life forms do we have to kill before cost savings aren't worth it?
Besides, we can have LEDs in better spectrums for under 1/5th the costs of incandescents. We just hired stingy motherfuckers and don't care about the repercussions of our decisions.
