CFLs do, they could not operate at all without somemercury. However they have much much less than older style fluorescent bulbs/tubes and the manufacturers are improving them so that today's CFL has less mercury than one from a couple years ago and a CFL made in a couple years should have even less.
LEDs don't.

Yes, compact fluorescent bulbs (CFLs) contain a small amount of Mercury that can be released if the bulb breaks. It is important to handle and dispose of them properly to minimize exposure to mercury. LED bulbs are a more environmentally friendly alternative since they do not contain mercury.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
No, energy-saving bulbs do not have a filament like incandescent bulbs. Instead, they use alternative technology, such as compact fluorescent lamps (CFLs) or light-emitting diodes (LEDs), to produce light in a more energy-efficient manner.
No, a low-energy light bulb generates less heat compared to traditional incandescent light bulbs. This is because low-energy bulbs convert more electricity into light, while incandescent bulbs produce more heat as a byproduct of light generation.
You can conserve energy with energy-saving bulbs by turning them off when not in use, selecting the appropriate brightness for each room, and utilizing natural light whenever possible. Additionally, regular maintenance and cleaning of the bulbs can help to ensure they are working efficiently.
Every household should contain one of the most energy saving products which is the light bulb as everyone uses electricity and it will cut down the costs of buying new light bulbs every week.
