Do CFL pollute more than LED?
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. … Unlike CFLs, LEDs can also withstand extreme temperatures, and they do not contain toxic mercury.
Why are CFL good for the environment?
In a CFL, an electric current is driven through a tube containing argon gas and a small amount of mercury vapor. … CFLs use about 75 percent less energy than incandescent bulbs. Saving energy helps the environment. Using less energy means less greenhouse gases will get into the air.
What happens if you inhale mercury from a light bulb?
Mercury in CFLs are present as elemental (or metallic) mercury. Once inhaled, the mercury vapor can damage the central nervous system, kidneys, and liver. These toxic effects are why any mercury spill should be handled carefully, including one that results from a CFL breaking.
Are CFLs bad for you?
Doctors at Stony Brook University in New York found that CFL bulbs produce significant levels of UVA and UVC emissions, which are harmful to human skin. This ultraviolet radiation can cause skin to age and burn and ultimately lead to skin cancer.
Are CFLs safe?
CFLs are marketed as “safe” and don’t pose any health risks as long as the glass remains intact. The danger comes if the bulbs are cracked, broken or not disposed of properly.
Are CFL lights safe?
Generally, CFL bulbs are energy-efficient and safe as long as you use them as directed. The truth of the matter is that while there are different types of fluorescent bulbs on the market, they all contain mercury vapor.
How do light bulbs affect global warming?
Because most electricity worldwide is generated by burning coal, which releases the greenhouse gas carbon dioxide (CO2), replacing incandescent bulbs with compact fluorescent light bulbs (CFLs) can reduce the amount of greenhouse gases emitted, especially in warmer climates, and have an impact on the amount of global …
