Are halogen bulbs more energy efficient than traditional incandescent bulbs?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

Typical halogen bulbs that screw into normal light sockets can be replaced with energy saving bulbs that operate at the same voltage.
