How can the cost of use CFLs be minimized?
The cost of CFLs was minimised by government subsidy, but in the UK that is now removed and the cost per bulb has risen to £3-4 each.
What are 3 things that visible light can be emitted by?
stars, flashlights, toasters, CFLs, LEDs, fireflies
What size of led lamp will be equivalent to 150 Watt halogen lamp?
LEDs and CFLs use about a quarter of a halogen so the answer is 35-40 watts.
Do energy saving light bulbs have mercury in them?
CFLs do, they could not operate at all without somemercury. However they have much much less than older style fluorescent bulbs/tubes and the manufacturers are improving them so that today's CFL has less mercury than one from a couple years ago and a CFL made in a couple years should have even less.LEDs don't.
Can a energy light bulb be usedwith a regular dimmer switch?
Some CFLs (Compact Fluorescent Lightbulbs) can be used with a regular dimmer. CFLs that can be used with a dimmer will be marked as such on the packaging. They are a little bit more expensive than non-dimming CFLs. It may be helpful to ask an employee at the store if you are unable to find the bulb you need. I tried one dimmable CFL and thought it was terrible. The light color was unnatural, it was slow to get bright, and the lowest dim setting was not very low. In the end, I returned it to Home Depot with less than 5 minutes use on it. I talked with a lighting store owner about "good" green lighting solutions, and he said that the technology just isn't there yet. Currently, if you want good light while saving electricity and increasing bulb life, simply dim the regular incandescent bulbs you have now (according to him). Of course, setting a dimmer to 80% isn't going to be as energy efficient as using a CFL, but it will offer some savings. I would expect better solutions within the next five years. I do use CFLs in my patio lights, and in some other lights that I don't care much what they look like. But for my "real" lighting, I use regular incandescents with dimmers. Hope that helps. -- Eric

How can the disadvantages of cfls be minimized?
The benefits of using CFLs could be maximized because when we are using CFL’s we think it is all good but it has some bad toxins that are creating the energy to make the light and make it use less energy. We have to dispose the CFLs properly to reduce the spread of the toxins.
What does the abbreviation CFLS stand for?
CFLS stands for Certified Family Law Specialist. It is an acronym used in California and describes a lawyer specialized in family law (eg. divorce and child custody).
Which item can the use of CFLs reduce the cost of energy?
Without knowing what the items are it is hard to know which CFLs can reduce the cost of energy. The items being referred to need to be given.
What percentage more efficient are CFLs?
I think it is 80% than the others
What are 3 things that visible light can be emitted by?
stars, flashlights, toasters, CFLs, LEDs, fireflies
How much amperage does a CFL draw?
Often CFLs are marked with the current. If not, find out the watts and the volts. Divide the watts by the volts to find the current, then double the current because the power factor could be as low as 0.5 with CFLs. That will tell you a safe value to use for the current when planning the wiring.
Why don't people always use energy saving lights?
The only widely-available replacement for the standard incandescent light bulb is the compact fluorescent light (CFL). While these bulb replacements (actually spiraled, gas-filled tubes) use much less electricity to operate, they cost much more to purchase and have other liabilities. People who don't always use energy-saving lights may simply have not gotten around to it yet, or they may have made a choice against them, balancing the positives and negatives. Here are some of the negatives related to compact fluorescents: * Initial cost of replacment CFLs is high, many times the cost of a light bulb. * Economic payoff may not come for a few years. * It's expensive to replace all the lights in a house at once. * Although these expensive CFLs are supposed to last much longer than light bulbs, they often don't. * Some CFLs are particular about which direction they're pointed; they don't last as long or put out as much light if pointed the wrong way. * Many CFLs don't immediately put out the full expected amount of light; they may take a few seconds--or longer, in cold areas--to warm up. * CFLs do not work well in very cold places. * Aesthetics: the look of a twisted coil is seen as less attractive than a glowing, lit globe. * The light put out by a CFL--generally the "cool white" color most fluorescent tubes produce--is dfferent from the red-yellow light people are used to in the home. (Although "blue-light" CFLs are becoming available.) * CFLs, as all fluorescents, flicker 60 times a second. Some people are uncomfortably sensitive to the flicker. * CFLs may also produce an irritating buzz or hum that some are disturbed by. * CFLs produce electromagnetic interference that can interfere with radio reception. * CFLs are not available as replacements for candelabra and other designer or specialty bulbs. * If a lamp or a light fixture cannot accommodate CFLs, a new fixture that does would have to be purchased and installed. * CFLs are not yet available as floodlights or spotlights. * The actual environmental impact of manufacturing a CFL is worse than for manufacturing a standard bulb; the CFL contains plastics, electronics, and mercury. * CFLs are generally not as weather-resistant as ordinary light bulbs. * A broken CFL (as with any fluorescent light) releases poisonous mercury. If broken over a carpet, there is no safe way a householder can clean up the chemical spill. It will likely be necessary to cut out a portion of the carpet. * There are tools available, using grippers or suction cups on long handles, for removing and replacing high-up light bulbs. Such tools will not work with most CFLs, and it is inadvisable in any case to grasp the tube itself and risk breakage. New designs of CFLs are coming out often; they may have now or soon solved some of the above issues. Lights that produce illumination through the use of LEDs (light-emitting diodes) are starting to be produced; they may be a superior and better-accepted solution.
Can you please share CFL's benefits?
Few concerns from my side...1 - Average lifespan of a CFL is five years2 - CFLs save $30 or more in energy costs over each bulb's lifetime.3 - CFLs generate 70 percent less heat, making them safer to operate.http://www.havells.com
How can people conserve electricity?
Turning off lights, switching to CFLs or LEDs, using the breeze to cool your house in the summer, etc.
