Common indoors type light bulbs, from most efficient to least efficient:
regular size tubular fluorescent lamps with electronic ballasts
CFLs (compact florescent lamps)
fluorescent lamps with reactive ballasts (old type of ballast)
incandescent halogen lamps
incandescent tungsten lamps
CFLs and LED lights are all very energy-efficient. In the long run LED bulbs will save you the most money. They cost more to buy at the beginning however last up 20X longer and also save you money at the same time.
An energy saving calculator can show you how much you can save. See Sources and Related Links.
The fluorescent light bulb uses much less energy, for the same amount of light, than the old-fashioned incandescent light bulb. A LED would use even less light, but those are, as yet, too expensive for general use.

In an energy saving light bulb, the electricity passes through a gas which causes it to emit ultraviolet rays. When these rays pass through the flourescent coating, the become visible, white light.
Actually an energy saving light bulb is simply any light bulb that uses significantly less electrical energy than an incandescent light bulb that produces the same amount of visible light energy. There are several technologies that can do this, two that have made it to the market are CFL (Compact Fluorescent Lamp) and LED (Light Emitting Diode).
The one mentioned above is the CFL (although the description given is marginal at best). LED bulbs are entirely solid state and thus involve no gas.
Some LED-array lamps now being made are hybrids: the light from the array impinges on a fluorescent material to gibe a stronger but more evenly diffused final light output. These can also be tweaked chemically to give a "warmer" light than the diodes alone give.
Of the common light sources, LEDs (Light Emitting Diodes) have the greater output in lumens per Watt. This is in comparison to Tungsten filament bulbs (including halogens) and compact fluorescent bulbs

The LED. It is also, for now, fairly expensive. The second-best choice for efficiency (and probably the best choice economically, for now) is the fluorescent light.
CFL of compact fluorescent light bulbs, often just called fluorescent bulbs, save energy. They are much more efficient than incandescent light bulbs, require less power and create less heat.
LED lamps consume less energy that incandescent lamps.
LED
The energy put into the bulb is converted to heat and light. Low-energy bulbs just use less electrical energy to keep them bright.
False. Low heat light bulbs can produce the same amount of light, and also save on energy.
No. Bulbs use energy, they don't provide it.
For Fathers Day 2011, think about eschewing the typical gifts and giving your dad something more practical. Change out all of the light bulbs in his home with energy efficient bulbs. Because energy efficient light bulbs use much less power than incandescent light bulbs, a house full of them will drop utility bills dramatically. When choosing energy efficient bulbs for Fathers Day 2011, you will have three options. First, you can swap out the bulbs for fluorescent lights. Fluorescent lights are inexpensive, but you will more than likely have to change out all of the lamps and lighting fixtures since the bulbs are not compatible with lamps that take incandescent bulbs. Next, you can opt for the compact fluorescent lamp (CFL) bulb, which are fluorescent lights that are made to fit into traditional light bulb receptacles. Not only do these bulbs use much less energy than regular bulbs, but they will also last much longer, saving your father money in the long run. Finally, you can choose to buy light emitting diode (LED) bulbs, which are also energy efficient. Because these are new, they are more expensive on the front end, but will last longer than CFL bulbs as well as use less energy.
One kilowatt-hour, or KWH.Additional AnswerYou don't 'consume power'; you consume energy. Power is a measure of the rate at which you consume energy.
so you consume less energy. the highest wattage is 60 on candleabra.
Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity
The difference between the two bulbs is that energy saving bulbs have murcuary in them which lowers the amount of electricity they require and consume.
For low energy bulbs the usual saving in input energy is a factor of 5, so a 95 watt bulb should consume about 20 watts. However this should be shown on the box, if you have it.
no
The energy put into the bulb is converted to heat and light. Low-energy bulbs just use less electrical energy to keep them bright.
Incandescente light bulbs waste quite a bit more energy than most alternatives.
No light bulbs actually save energy, they use it to produce light. However energy efficient bulbs use less energy than the ordinary incandescent type. To my mind describing them as energy saving is wrong, they should be described as "lower energy" bulbs.
Usually the light bulbs used are resistive components, but the energy savers used now a days are inductive components and they are used because they consume reactive(inductive) less useful power and save useful or real (resistive) power.
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
Not exactly they get less energy from the animals they consume.
