I swapped every light in the Spodefly World Headquarters and Bunker Compound to CFL. They seemed fine ... got used to it. Didn’t notice any massive swings in electrical bills.
Recently tho, I found a light that someone was discarding. Basically a pole, with a bulb on top and a cone that directs the light up. It has a dimmer built into it. I put my last 60watt incandescent bulb into it, and turned the dimmer to low ... and what beautiful light.
A soft, deep orange glow that is beautiful. Made me hate the greenish, pasty CFLs.
Also, I had a CFL “burn out” not long ago ... very spectacularly. At first it just went out. No fanfare, just stopped making light. About 5 seconds later tho there was a horrible arc welding sound, followed by the stench of frying electronics, which I assumed to be mostly toxic due to the mercury in the CFLs, so I turned on all the fans and opened all teh windows and herded the cats into a different part of the house till it cleared up
And no, I didn’t observe some government enforced disposal ritual ... I threw the son of a bitch in the trash.
In a practical world that's what most will do.
