Why do stores offices and schools use fluorescent lights instead of incandescent?

Incandescent lights are expensive to run (they give off a lot of heat was well as light), incandescent lights are much more efficient. However modern LED light bulbs are better (more efficient) than both incandescent and fluorescent lights so in the future you will see a change to the use of these.


Why does replacing incandescent light bulbs with compact fluorescent bulbs conserve electricity?

Because instead of using a 40, 60, 75 or 100 watt bulb, you can get the same amount of light with using less electricity to run a fluorescent bulb. For example, if you are looking for the equivalent light output of a standard 100w incandescent, look for a 25w cfl (compact fluorescent light)Another basic way to understand this is that incandescent bulbs produce a lot of heat along with the light they emit. They produce much more heat than the compact fluorescent bulbs. The heat from incandescent bulbs doesn't just come from thin air; it is a product of the electricity that is consumed by the bulb. This heat is called 'entropy' because it is wasted energy; it represents expended energy that can never be recaptured to do other things. The compact bulbs produce less entropy or wasted heat, and are therefore more efficient and environment friendly. If you are imagining that the heat from incandescent bulbs could very well be 'captured' and used for other things, realize that the 'capturing' process must itself involve the expenditure of energy, and at every step there is a huge loss of efficiency. Heat can be collected, but never without a cost; that cost is entropy.


Which light bulb uses more energy?

Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.


What is the most energy efficient light bulb?

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.


Does a 60-watt electric light bulb create heat energy?

Yes. Part of the energy is converted to light, part to heat. The percentage depends on the type of light bulb. Fluorescent and LED light bulbs are more efficient than incandescent light bulbs. A 60-watt incandescent bulb will be uncomfortable to remove from the socket with your bare hands after turning it off. However, a 100-watt bulb will burn you if you remove it with your bare hands after turning it off.

What can one use CFL lamps for?

CFL stands for Compact Fluorescent Lamp, and they are an energy-efficient alternative to incandescent bulbs. CFL lamps can be used to replace these bulbs, and they can be placed both indoors and outdoors.


Are compact fluorescent bulbs cool to the touch?

Relatively cool, yes, especially if you compare them with incandescent lightbulbs.


Do CF light bulbs produce as much heat as incandescent bulbs?

No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.


Information on CFL light bulbs?

A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.


How much is it for lighting?

Lighting is not one of the major electrical costs in a house, especially if CFL (compact fluorescent lamps) or LED bulbs are used. If lighting costs are an issue, get rid of incandescent bulbs and halogen bulbs. CFLs are cheaper and nearly as efficient as LEDs.


Compact fluorescent lights are better for both our wallet and the environment but do they produce better light than the traditional incandescent bulbs?

Yes, the compact fluorescent light produce more light as compared to the same wattage of incandescent light, it is scientifically proved.


Do incandescent and fluorescent bulbs produce the same amount of heat?

No, incandescent and fluorescent bulbs do not produce the same amount of heat.


Which Lighting will be the most energy efficient?

Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.


Do incandescent light bulbs waste less energy than compact fluorescent bulbs?

Incandescente light bulbs waste quite a bit more energy than most alternatives.
