Incandescent light bulbs are officially banned in the U.S.::America’s ban on incandescent light bulbs, 16 years in the making, is finally a reality. Well, mostly.
The 3 biggest issues CFLs had were their warm up time, especially in cold weather, the flicker some people are sensitive too, and they contain murcury as all florescent bulbs do. That means it is absolutely necessary to properly dispose of them so mercury doesn’t get into the ground water.
One problem is that CFL bulbs is that they contain small amounts of mercury (about 4mg per bulb). Because of that, disposing of them responsibly requires going through big hassles rather than just throwing them in the trash. Also, because of that mercury, accidentally breaking one means contamination of the environment around the break.
Flickering - always was a big problem for these things.
Longevity: They were very sensitive to heat, which meant that they loved to burn themselves up in a lot of applications.
Dimming: CFLs were NEVER good at being dimmable.
CFL was just a very poor technology detour on the way to the vastly superior LED lights.
CFLs aren’t good at dimming because they are not dimmable. Trash light bulb tech, don’t get me wrong, but you cannot even dim them to begin with. I’ve tried dimming them back when I didn’t know any better and had one of the fuckers literally explode in front of my very eyes.
Some were produced that were claimed to be dimmable - and I wasted my money on a few and was still unhappy with them. The other problem I forgot to mention earlier was the startup time: the earlier bulbs (and the cheaper ones) wouldn’t just ‘turn on’ when the power was turned on…they took some time to start making light, and the colder it was the longer it took - this is an aspect where LEDs are amazing - maximum brightness within milliseconds of getting energized.
