Which describes a compact fluorescent light bulb?
Compact fluorescent lamps are functionally identical to linear fluorescent bulbs. Both are gas-discharge lamps that use electricity emitted from cathodes to excite mercury vapor contained within the glass envelope, using a process known as inelastic scattering.
What is the difference between fluorescent and compact fluorescent light bulbs?
Q:What’s the difference between a compact fluorescent light bulb and a linear fluorescent bulb? A: The primary difference is size and application. Compact fluorescent bulbs are made in special shapes (which require special technologies) to fit in standard household light sockets, like table lamps and ceiling fixtures.
What are compact fluorescent lamp used for?
Compact fluorescents are being used in residential applications replacing incandescent and halogen lights. They provide relatively shadow-free lighting in residential applications and because of their small size can fit nicely into sconces, ceiling lights and table lamps.
What are the different types of compact fluorescent lamp?
8 Types of CFL Light Blubs #1 – Spiral CFL Bulbs. The most popular type of compact fluorescent light bulb is the spiral shape. #2 – Incandescent Shaped CFL Bulbs. #3 – Globe CFL Bulbs. #4 – Tube CFL Bulbs. #5 – Candle-Shaped CFL Bulbs. #6 – Circular CFL Bulbs. #7 – Post CFL Bulbs. #8 – Reflector CFL Bulbs.
What is in a compact fluorescent?
In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.
Which is better CFL or LED?
Longevity—With a lifespan of approximately 25,000–35,000 hours, an LED bulb lasts 2 to 4 times longer than a CFL, and 25 to 35 times longer than a standard incandescent bulb. LEDs are more efficient than even CFLs: A 16.5-watt LED bulb is equivalent to a 20-watt CFL and a 75-watt incandescent.
What are the disadvantages of CFL?
Some of the disadvantages of compact fluorescent bulbs are that they are cold temperature sensitive, not recommended for enclosed fixtures, can have a higher initial cost than incandescent, have a longer warm up time, they may have limited color temperatures, do not dim nearly as smoothly, and dimming decreases the.
Do compact fluorescent bulbs get hot?
Incandescent and CFL bulbs get so hot because most of their energy is being released as heat, not light, making them much more ineffeicient. Proprietary tests show 100W incandescent lights burning at 335.4 F, CFL lights burning at 179.2 F and LED bulbs burning at 87.2 F.
How many watts does compact fluorescent lamp use?
Compact fluorescent bulb wattage ranges from 11 to 42 watts. They use 75% less energy than the equivalent incandescent bulbs, which range between 40 and 150 watts. Some of the most common CFL wattage equivalents are 13 watt CFL (equivalent to 60 watt incandescent) and 23 watt CFL (equivalent to 100 watt incandescent).
Why are compact fluorescent bulbs better?
Because CFLs use less electricity than traditional light bulbs, they reduce demand for electricity; that reduction means less greenhouse gas emissions (including less mercury) from power plants. CFLs contain a very small amount of mercury — an average of 4 milligrams in each bulb.
What are the advantages and disadvantages of compact fluorescent lamps?
While initially they cost more, CFLs are less expensive in the long run because they last much longer than incandescent bulbs. And since CFLs use a third of the electricity and last up to 10 times as long as incandescent bulbs, they are much less expensive overall.
Why are compact fluorescent lamps preferred over electric bulbs?
Compact fluorescent lamps (CFLs) are preferred over electric bulbs because CFL’S consume less energy and they will not waste the energy in the form of heat.
Do compact fluorescent bulbs contain mercury?
CFLs contain very small amounts of mercury Mercury, an essential part of CFLs, allows a bulb to be an efficient light source. No mercury is released when the bulbs are intact (i.e., not broken) or in use, but mercury vapor and very small beads of mercury can be released when a CFL is broken.
Are compact fluorescent bulbs LED?
And that’s before we even analyze which one is more energy efficient! In short form, here are the answers: CFL is the curly light bulb and LED is the long light bulb. And, in the CFL vs LED battle for energy efficiency, the LED light benefits make it a winner, hands down.
Should I replace CFL with LED?
If your CFL bulbs are working, it’s usually not worth replacing them with LEDs immediately – LEDs are more efficient, but the savings aren’t huge. Only replace them now if your CFLs aren’t suited to the fitting or are damaging fabrics. Otherwise, wait until they’re burned out.
Why LED is used instead of CFL?
The LED bulbs last longer and therefore will save you time and money in the long run. CFL’s use 25-35% less energy than traditional light bulbs, or incandescent bulbs, use. LED’s, on the other hand, use 75% less of the energy than incandescent bulbs use. This means that LED bulbs are incredibly energy efficient.
