How are CFL light bulbs better than regular light bulbs?
A CFL uses 65% less energy and can reduce your power bill as well.A longer answerSince major improvements in the design of Compact Fluorescent Lamps (CFLs) from 1990 onwards, by using a CFL light bulb 80% energy of the energy can be saved compared to the energy that is needed to produce a given amount of artificial light using conventional incandescent filament bulbs.In other words, to produce the same amount of visible light, a modern CFL uses only 1/5 (one fifth) of the power that an incandescent filament bulb uses.For example, a 20 watt CFL bulb produces similar light to a 100 watt incandescent filament bulb and a 30 watt CFL matches the light output of a 150 watt incandescent filament bulb.CFLs also have a much longer useful life-span, thus avoiding the need to change them as often as incandescent light bulbs.Another opinionThere are issues with the additional power used to manufacture CFL bulbs and the toxic chemicals inside these units.But, whilst they certainly do save energy for the end user, their drawbacks are that they probably use more energy overall and their manufacture causes more pollution.
What are some different names of light bulbs?
CFL or LED
What is the difference between CFL and fluorescent?
There is no difference. CFL is an abbreviation for Compact Fluorescent Light which has simply been designed to take up less space than the standard tubes.
How many joules are there in a led bulb?
Since LED bulbs come in a variety of sizes there is no one answer. If we consider Watts then LED bulbs from 1 to 12 Watts are common. The higher end of quality LED lights that are commercially produced generally yield about 80 lumens per Watt. This means for a 10 Watt LED bulb your looking at 800 Lumens. This is higher than both CFL and incandescent lights. LED bulbs can save money in the long run due to the lower energy use, but they require a larger up front investment. See below for a link to an example of an LED bulb that produces 460 lumens.
How does CFL function to minimise loadshedding?
it consumes less energy than ordinary bulbs do.thus it conserves electricity and reduces the chances of loadshedding.
Are cfls good?
Over all, CFL light bulbs are good for the environment and they can save $. 1 CFL light bulb has 10 times the life span of a regular light bulb. 1 CFL light bulb could save enough energy to take a car from NY to San Francisco. 1 CFL light bulb uses between 50% and 80% less energy than a regular light bulb.
How does light from cfl bulb compare?
When you compare a CFL (Compact Fluorescent Lamp) bulb to an LED bulb, the CFL bulb has a shorter lifespan. The CFL bulb also uses more electricity for the same brightness Also a CFL lasts longer and uses less electricity (for the same brightness) than an incandescent bulb.
What is the energy reducing light bulb called?
They are called CFL light bulbs. CFL stands for Compact Fluorescent Light .
What does a CFL light use on a incandescent light bulb?
one half
Who invented the cfl light bulb and when?
Edward Hammer in 1976.
Is there a compact fluorescent bulb that's equivalent to a 120V bulb?
As long as the CFL has an intermediate base it can be interchangeable with any ordinary light bulb that has an intermediate base. Look on the packaging as to comparability. Look on the box for equivilant outputs between lamps to compare wattage bulbs to CFL's.
How bright is 400 lumens?
This is a bit less light than a 40W incandescent bulb (much less than a 9-watt CFL bulb, but twice as much as a 5-watt CFL mini-bulb).
What does par mean when refers to CFL light bulbs?
What does "PAR" mean when associated with light bulbs? Is it the CFL watt equivalent of an incandescant bulb? Thanx, Bob Cushman
How much energy does a CFL light bulb save versus an incandescent bulb?
About 80%. An incandescent bulb produces 12 lumens per watt, (15 for halogen) while a CFL produces about 60 lumens per watt.
What does Mercury do in a CFL?
Without the mercury in a CFL you wouldn't have light. The ballast in a CFL supplies initial current which excites the mercury which releases photons, or light. The mercury does not produce visible light, this happens only once the light passes through the phosphor coating on the inside of the bulb.
What light bulb uses less amount of energy?
compact flourescent light bulbs (cfl) the swirly ones
What is the green efficient squiggly light bulb called?
Florescent light-bulbs CFL Compact Fluorescent Lamp
