Not as bright as normal light bulbs (higher watts though)
-Compact fluorescent bulbs use 66% less energy than a standard incandescent bulb, and last up to 10 times longer.
-A 32-watt CFL can save a homeowner $30 in energy costs over the life of a bulb.
-Lower weight and size, has a more attractive shape.
-Easier and less frequent replacement.
-Less maintenance cost.
They burn the skin if you touch them directly. They have to be changed, as they burn out. Changing them is a pain, with the degree of pain varying on where exactly it is located. Also, bulbs break and the glass shards could easily cut someone if they're not careful. Bulbs tend to be too bright, as looking at one directly (without any covering/shade) could be like looking into a synthetic sun. Should the covering be lost or broken, replacing it could be a pain, as would choosing to put up with the unbridled light of the bare bulb.
what is the disadvantages of thelightbulb? The biggest disadvantage of the light bulb is the heat that is given off by the bulb. On most bulbs this heat is wasted energy that is paid for and it is not being used. Another disadvantage is the fragility of the bulb in a vibration environment. When the light bulb is on, the filament can break very easily with the slightest vibration.
The types of bulbs in use in the home are incandescent (regular), halogen (improved incandescent), compact fluorescent (CFL) and light-emitting diode (LED).
The amount of light produced is measured in lumens, while the amount of electric power used is measured in watts.
Some manufacturers confuse the issue (perhaps deliberately) by measuring the light in 'equivalent watts'.
The efficiency of bulbs is measured by the amount of light produced for each watt consumed, in other words, lumens per watt.
The efficiencies for the four types are:
Incandescent: 12 lumens per watt - typical life 1000 hours
Halogen: 16 lumens per watt - typical life 2000 hours
CFL: 50-60 lumens per watt - typical life 8000-12,000 hours
LED: 70-90 lumens per watt - typical life 25,000 hours.
Thus regular light bulbs should be replaced by CFLs or LEDs by anyone wishing to pay less for their lighting.
bulb absorbs some power. this power is desipated as heat
compact fluorescent light bulbs
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.

Yes, you can put a fluorescent light bulb in your floor lamp. You need to see what size bulb the lamp takes, but most sizes can be purchased as florescent bulbs.
Compact fluorescent light bulbs contain mercury. (For that reason, it is important to be very careful with a broken compact fluorescent bulb, because mercury is highly toxic.) Most other kinds of light bulbs do not contain any significant amount of mercury.
Fluorescent bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in the bulb.
fluorescent light bulbs are usually from 9$-15$.

Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
It is unlawful for anyone to dispose of fluorescent bulbs as univeral waste.
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
The weight of one 8 foot fluorescent light bulb is 1.2 pounds. Fluorescent light bulbs are available in many colors and color temperatures.
There is no fluorescent light bulb that is better then any other. That is why they are suggested to be used since they have no different objects.
They are called CFL light bulbs. CFL stands for Compact Fluorescent Light .

it all depends on the voltage the light bulb can sustain.
