When you compare a CFL (Compact Fluorescent Lamp) bulb to an LED bulb, the CFL bulb has a shorter lifespan. The CFL bulb also uses more electricity for the same brightness
Also a CFL lasts longer and uses less electricity (for the same brightness) than an incandescent bulb.
Over all, CFL light bulbs are good for the environment and they can save $. 1 CFL light bulb has 10 times the life span of a regular light bulb. 1 CFL light bulb could save enough energy to take a car from NY to San Francisco. 1 CFL light bulb uses between 50% and 80% less energy than a regular light bulb.
They are called CFL light bulbs. CFL stands for Compact Fluorescent Light .
As long as the CFL has an intermediate base it can be interchangeable with any ordinary light bulb that has an intermediate base. Look on the packaging as to comparability. Look on the box for equivilant outputs between lamps to compare wattage bulbs to CFL's.

This is a bit less light than a 40W incandescent bulb (much less than a 9-watt CFL bulb, but twice as much as a 5-watt CFL mini-bulb).
What does "PAR" mean when associated with light bulbs? Is it the CFL watt equivalent of an incandescant bulb? Thanx, Bob Cushman
Without the mercury in a CFL you wouldn't have light. The ballast in a CFL supplies initial current which excites the mercury which releases photons, or light. The mercury does not produce visible light, this happens only once the light passes through the phosphor coating on the inside of the bulb.

Florescent light-bulbs CFL Compact Fluorescent Lamp
The swirly light bulb is called a compact fluorescent lamp (CFL). It is a type of energy-efficient light bulb that produces light by using electricity to excite the gas inside the bulb to create illumination.
The curly light bulb is called a compact fluorescent lamp (CFL). It is designed to be more energy-efficient than traditional incandescent light bulbs.
