Well, if they're both 40 watt bulbs they use the same amount of electricity. But incandescent bulbs produce a lot of heat as well as light. Fluorescent bulbs don't produce (much) heat, so they can use their power to produce light. So you can use fluorescent bulbs of lower wattage to produce the same amount of light.
So for the same amount of light, fluorescent bulbs use less electricity than incandescent bulbs.
How much electricity is consumed depends only on the power Wattage of the light bulb.
No matter what types of bulbs they are, a 100 Watt bulb will always consume more electricity than a 60 Watt bulb.
The type of bulb makes no difference to how much electricity is consumed but does make a big difference to the amount of light that is produced.
In general:
* a 100 Watt halogen bulb will produce more light than a 100 Watt normal incandescent light bulb;
* a 20 Watt compact fluorescent light (CFL) bulb will produce about the same amount of light as a 100 Watt incandescent light bulb.
If you are asking if, for the same wattage, a halogen bulb produces more light output than a traditional incandescent bulb, the answer is yes.
This means that, to get a given amount of light, you can sometimes use a lower wattage halogen bulb than what you would need to use if it were a traditonal incandescent bulb.
So another answer to your question is yes, you can save money on the running cost for electricity if you use a halogen bulb which has a lower wattage than the traditonal incandescent bulb.
However, to be able to use the halogen type, you might have to change the bulb-holder and shade used in your present light fitting!
NoteWe pay for the total energy consumed, not for the current taken by any particular sorts of bulbs - or indeed any types of appliances - whilst they are being used.The cost of the energy used is calculated in units of kilowatt-hours at whatever charge is relevant for the time of day, all according to the agreement you have with the energy supplier in your area. (Usually an energy utility company.)For the full details of the costs and charges made by the utility company that supplies your area, just read one of your electricity bills.If you pay 20 cents per kilowatt-hour (kW-h) of energy and you use a 50 watt bulb for one hour, you'll pay for (50 x 20) / 1000 cents, which equals just 1 cent - no matter what type of lamp you use. In particular it is worth noting that the bulb's voltage doesn't come into this calculation.
A typical 20-watt compact fluorescent light bulb can produce about as much light as a 100-watt incandescent light bulb. There is an 80 per cent improvement in efficiency.
Typical halogen bulbs that screw into normal light sockets can be replaced with energy saving bulbs that operate at the same voltage.
Steam generators are quite efficient because it does rely on traditional energy source such as oil or coal. However, because it uses nuclear power, there is always a threat of a nuclear meltdown unless absolute precautions are taken.
I would assume it means that the more efficient it is, the less energy it intakes and the more efficient the system is at retaining the energy it intakes.
Gas-fired, storage-based water pumps are the most energy efficient type.
The energy consumption of a modern Cree XP-G or XM-L based flashlight with 170 lumen output can be as low as 1.4 watts with 120 and more lumen per watt. The light output will be approximately equal to a 20 W tungsten incandescent light bulb or a 10 W halogen light.
It's a device that can convert energy of one form into another efficiently. Like a lightbulb for example, an energy efficient one would use less electricity but still produce as much light as one that is less efficient. It's a measure of what you get out versus what you put in.
Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
Light bulbs in order of the least to most energy efficient : incandescent, halogen, fluorescent, LED. For home owners, most reasonable is the CFL lightbulb, which is cheaper and longer lasting than the LED.
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
The type of light bulbs that waste the most energy are incandescent bulbs. They are least efficient because around 90% of the energy is lost on heat. They are also the shortest-lived light bulbs. The most efficient lights are LED lights, followed by CFLs, followed by the new Halogen incandescent bulbs. See the related link below for more information.
Halogen+++No longer. LED-based fluorescent lamps use a lot less electricity than halogens for similar light levels - much of the energy emitted by a halogen lamp is heat, although it is more efficient than the equivalent argon-filled incandescent lamp. (A halogen bulb is still an incandescent type - it simply uses a different gas filling from the conventional bulb.)
Yes.
Energy efficient incandescent light bulbs can be purchased from most lighting stores and major supermarkets. They can also be purchased online at places like Home Depot, Amazon and Earth Easy.
You can use incandescent, fluorescent or halogen lighting fixtures meant for indoor use inside a home. For example, you can purchase incandescent wall lights that are connected to a dimmer switch with incandescent lamping. Fluorescent lights might be in models of ceiling lights, chandeliers and pendant lights. Fluorescent lights are energy efficient lighting choices. Halogen lamps are used in some recessed lighting for indoor use. Floor lamps may also use halogen bulbs. Read carefully to see what type of indoor lighting can withstand damp settings such as the bathroom.
LED light fixtures are made out of clusters of very small, super energy efficient bulbs. Because many of those bulbs are used, LED lights can be built to mimic the effects of regular incandescent bulbs. A huge part of what makes LED bulbs so energy efficient is that they do not produce heat as incandescent light bulbs do.
Incandescent light bulbs are inefficient at converting energy into light. They are so inefficient that in many places there is no a ban on the sale or manufacture of incandescent light bulbs in favor of higher efficiency CFLs, LEDs, or halogen lights.

Fluorescent lighting is cooler and far more energy-efficient than incandescent lighting.
