What is a CFL Light Bulb?
Compact fluorescent bulbs , also called CFLs, are an energy-efficient replacement for traditional incandescent light bulbs . Within an incandescent bulb, electric energy heats up a slender filament to the level which it glows. This style generates a comfortable, gentle light, however the light bulb will lose the majority of its energy as heat. In CFLs, electrical current stimulates argon and mercury vapor, which excites a glowing phosphor covering within the light bulb. This style will lose hardly any energy to heat, meaning it uses significantly less energy than a similar incandescent light bulb.
CFL lights usually price a little more than incandescent light bulbs, however they will pay for themselves in energy costs savings. There isn't any industry standard for calculating energy efficiency, so energy savings ratings will be different from company to company. Generally, a CFL uses close to 75% less electrical power than an incandescent light bulb with similar lighting output, although enduring about Ten times longer. In addition, because CFLs generate much less heat, they could help you save on air conditioning costs.CFLs are available in a variety of designs, sizes, color temperatures, and illumination levels, which makes it easy to switch most incandescent light bulbs with an energy-efficient CFL option. Even though the initial technology of CFLs experienced a characteristic glowing blue color, more recent models do a sufficient job re-creating the nice and cozy glow of incandescent light sources.
Light Bulb Terms
Lumens – The conventional unit of lighting output for light bulbs is the lumen. A larger lumen number signifies a brighter light bulb, and a lower lumen number implies a dimmer light. A CFL as well as an incandescent light bulb with the exact same lumen rating will generate the equivalent amount of lighting.
Watts – Light bulb producers have customarily used watts to signify light output, but wattage is really a way of measuring energy usage, not brightness. Given that CFLs take much less energy, a CFL will have a reduce wattage than an incandescent light bulb that creates the equivalent light. Quite simply, a lesser wattage amount signifies higher energy cost savings, not reduced light output.
The Truth about CFL Bulbs
Misconception: Getting a recycler is difficult.
Actuality: You shouldn't toss used CFLs out with the garbage. But Home Depot , Ikea, plus some Ace and True Value retailers take unbroken CFLs regardless of where you purchased them. Wal-Mart sells by far the most CFLs. A spokeswoman informed us the company was considering a recycling plan, however it didn't have one as we went to press. You may also speak to your public works division or visit www.epa.gov/bulbrecycling .
Misconception: You have to wear a hazmat suit in the event you drop one of those light bulbs.
Actuality: Contact with damaged CFLs can cause a health risks, particularly to your unborn infant or toddler. But don't worry. Open a window, turn off central A/C or forced-air heating system, and clear the space for around Fifteen minutes as the Epa suggests. Make certain to keep CFLs out of table lamps that may very easily tip, specifically in areas used frequently by young children or expecting mothers.
Misconception: CFLs create a unpleasant blue light.
Actuality: Several now light like regular light bulbs. Those with a 2,700 to 3,000 Kelvin (K) number have got a warmer, yellower shade; 3,500 K to 6,500 K light bulbs give off a bluer or whiter lighting. Energy Star CFLs need to contain the Kelvin amount on the package as of December. Seek out CFLs described "soft" or "warm" white for light just like an incandescent's, and pick "bright white," "natural," or "daylight" for whiter lighting.
Misconception: CFLs require time and energy to switch on.
Actuality: Turn-on has become just about immediate. But many CFLs we examined required about Thirty seconds to achieve 80 % of their illumination, and a few flood and outdoor lamps required 90 seconds or even more. That's why some seem dim initially and aren't suitable for locations like closets or stairways.
Misconception: CFLs incorporate a lot of mercury.
Actuality: Each and every light bulb includes a very small fraction of the mercury inside a conventional fever temperature gauge. Energy Star CFLs call for 5 milligrams or less for light bulbs which use under 25 watts. Our evaluating indicates that some have near 1 milligram.
Misconception: Compact fluorescent lightbulbs discharge mercury while they burn.
Actuality: The mercury is enclosed within the glass tubes.
Misconception: CFLs smoke when they burn out.
Actuality: Today's expended bulbs generally flicker, dim, or produce a reddish-orange ambiance. If one you own smokes or smolders, switch off power to the light and permit the light bulb to cool before extracting it .
