No. Of course not. More purposeful misinformation

When was the last time you priced a halogen floodlamp?

At my Home Depot, the 6 packs of 60-watt equivalents came out to $1.70 each.

Would? Or might? How many marine radios and battery-powered emergency exit
signs is there in the typical home?

I have found that the built-in electronics go wacky when the AC voltage to
them goes below a certain threshold when dimmed. There is hysteresis in the
effect. This occurs even with hard-wired,  20-amp dimmers with toroidal
chokes the size of donuts and with no X-10 anywhere in the house.
