Fluorescent light bulbs are more energy-efficient than incandescent bulbs. … They take time to reach their full brightness and tend to be slightly more expensive than incandescent bulbs but last much longer. There is some concern about the fact that they contain mercury.
What are the advantages of using a fluorescent bulb instead of an incandescent bulb?
Fluorescent lamps also do not produce as much heat as traditional lighting options. They make about 75% less heat compared to an incandescent bulb because they are not using resistance to emit light. That also results in an energy savings, and also helps to keep whatever room they are in at a cooler temperature.
What are the advantages of fluorescent light bulbs?
Fluorescent Light Tube Advantages
- Energy efficient- so far the best light for interior lighting.
- Low production cost (of tubes, not of the ballasts)
- Long life of tubes.
- Good selection of desired color temperature (cool whites to warm whites)
- Diffused light (good for general, even lighting, reducing harsh shadows)

Why incandescent bulbs are banned?
But the US energy department said banning incandescent bulbs would be bad for consumers because of the higher cost of more efficient bulbs. The Department of Energy said it had withdrawn the ban because it was a misinterpretation of the 2007 Energy Independence and Security Act.
What is bad about fluorescent light bulbs?
The Bad: Fluorescent tubes & CFL bulbs contain a small amount of mercury gas (about 4 mg) – which is toxic to our nervous system, lungs and kidneys. So long as bulbs stay intact, the mercury gas is no threat. This means bulbs should be handled properly to avoid breakage.
Which light bulb is better incandescent or fluorescent?
Fluorescent light is a bright light produced by electricity flowing through a tube filled with ionized gas. Fluorescent light bulbs are more energy-efficient than incandescent bulbs. They take time to reach their full brightness and tend to be slightly more expensive than incandescent bulbs but last much longer.
Which is safer LED or CFL?
LEDs use significantly less energy than even CFLs, and do not contain mercury. … A study published in late 2010 in the journal Environmental Science and Technology found that LEDs contain lead, arsenic and a dozen other potentially dangerous substances.
Are fluorescent lights bad for your eyes?
Exposure to harsh fluorescent lighting can cause eye strain and blurred vision. The longer you’re exposed to the light, the more likely you’ll experience the problem. Symptoms of eyestrain include sore, burning, watery or dry eyes. Double vision and increased sensitivity to light can also occur.
Do fluorescent lights cause cancer?
Ultraviolet radiation emitted by fluorescent lighting can increase an individual’s exposure to carcinogenic radiation by 10 to 30 per cent per year, with an associated increased probability of contracting squamous cell carcinoma by 4 percent. Melanoma has been shown to not be affected by CFLs through normal use.
What are the advantages and disadvantages of incandescent light bulbs?
➨It is warm source of light and hence requires air conditioning to cool the room. ➨It has higher operating cost. ➨It is very fragile and hence needs to be handled very carefully. ➨It generates low lumen per watt.
Can I still buy incandescent bulbs?
Unfortunately, little of that is true. There is no such thing as an incandescent light bulb ban in the United States. In fact, on the very same day that the 60-watt incandescent light bulb disappears, you’ll be able to buy a 43-watt incandescent light bulb to take its place.
Are incandescent bulbs better for your eyes?
Bright white and cool fluorescent tube bulbs and incandescent bulbs emit the most UV radiation and cause the most damage to your eyes. … They also state that extended exposure to sunlight, especially in the teenage years and for those that don’t wear eye protection, can also lead to eye damage.
Is it illegal to sell incandescent light bulbs?
Basics of the Energy Independence and Security Act of 2007, as it pertains to lighting and light bulbs: It does not ban the use or purchase of incandescent bulbs. It does not ban the sale or manufacture of ALL incandescent bulbs, just those common household incandescent (and other) bulbs that are not energy-efficient.
Do fluorescent lights use a lot of electricity?
Fluorescent lamps, including compact fluorescent lights (CFLs), use about 75 percent less energy than incandescent bulbs and last six to 15 times as long, according to the U.S. Department of Energy (DOE). But it’s widely believed that these popular bulbs use a lot of energy to start up. Otherwise, turn the light off.
Can fluorescent lights make you sick?
If the fluorescent lights in your office cause you discomfort, you may have photophobia, or light sensitivity. You might find yourself blinking excessively or squinting to try to filter out some of that light. Maybe your eyes begin to tear up. You may even get a headache or feel sick to your stomach.
Do fluorescent lights age you?
In one study out of Stony Brook University, fluorescent bulbs in particular were proven to have a higher incidence rate of defects that lead to UV radiation emission levels that could burn skin and evoke cell death, leading to premature skin aging and wrinkles.
