> The US has banned[1] the (previously) standard low temperature (~2500k) incandescent light bulbs
Not true. They established minimum efficiency rules. Old 60W bulbs can meet the rules but 100W cannot. You can still buy 60W incandescent bulbs everywhere.
If a 60 watt bulb lasts 1000 hours at $0.10/kWh, that's $6 even if the bulb was free. So quadrupling the price has negligible effect on its total cost ($6.25 vs $7.00).
The skeptic in you would be pleased to know those "post-ban" bulbs fail much faster, and live about a quarter of the time.
As much as I tried to avoid all of these new ugly light bulbs (never met a florescent that looked right, and it took me a long time to find an acceptable LED), I eventually just got rid of all incandescents and got CREE warm whites.
