the standard would be more than doubled to more than 120 lumens per watt. Commonplace 60-watt equivalent lightbulbs would only require a maximum of 6.5 watts,

The first set of LED bulbs I found on Lowe's had these specs:

60 Watt replacement using only 8.5 Watts (760 lumens)

Or about 90 lumens per watt. So modern LED bulbs will have to be replaced with more expensive ones. Right now LED bulbs are so cheap to run that I don't bother turning them off when I leave the room like I had been trained to from childhood. I also do things like leave porch lights on all night that I never would have done with 60 W incandescens.

I wonder how much of the typical household electric bill is lighting with current LED bulbs? How much will a 25% decrease in electricity usage on that part really save?

Light emitting diodes are low voltage DC devices.

So screwing them into a 110VAC socket requires a power supply. Which generates a lot of heat.

I have a high failure rate on my LED light bulbs, none of then “burn out” the power supplies do.
