Neon Lights:The Good and The Bad.
E N D
atomic weight 20.180,melting point -248.67°C, and boiling point -245.95°C. Neon lights have been known to be harmful to all living organisms, but helpful for good business. Studies have shown how neon lights may seem to have inert gases that are other wise unable to harm the atmosphere, or us but they seem to have other affects. Neon is a rare, inert gaseous element occurring in the atmosphere to the extent of 18 parts per million and obtained by fractional distillation of liquid air. It is colorless but glows reddish orange in an electric discharge and is used in display and television tubes. Its Atomic number is 10;
is deceptive, you have to build a lot of those bulbs to equal the value of one fluorescent system. Second, although there is considerable energy consumed in manufacturing the complicated components of a fluorescent lamp, it's unlikely to more than a few kilowatt-hours, the equivalent of the extra energy a 100 watt incandescent light uses up in a week or so of typical operation. Yes, fluorescents are more energy efficient overall. To begin with, fluorescent lights have a much longer life than incandescent lights, the fluorescent tube lasts many thousands of hours and its fixture lasts tens of thousands of hours. So the small amount of energy spent building an incandescent bulb
So it may take a week or two to recover the energy cost of building the fluorescent light, but after that the energy savings continue to grow for years and years. So the benefits of this neon lights are for the consumer sake as in selling advertisements and all types of business. However, this cannot compare to the harm it does in our community and our natural environment. For many years mercury has been used to make paint., batteries, pesticides, skin cream, dental fillings, and even vaccines. Sometimes called quicksilver, mercury is an extremely dangerous metal which becomes liquified at room temperature. In America’s factories tones of mercury by-product is poured into the air each year. On rainy days the mercury is carried from the air into ponds and streams
where concentrations of it are found in seafood of all types.
Mercury has several unique and useful properties that have led to widespread use. It is the only metal that, in its pure form, is a liquid at room temperature. Liquid mercury is volatile, meaning that it easily evaporates to form a poisonous vapor. Mercury conducts electricity and expands at a constant rate in response to changes in pressure or temperature. Replacing conventional lights with compact fluorescent bulbs, are a popular energy conservation measure promoted as a way to fight global warming; could create toxic nightmares for unsuspecting consumers. Compact fluorescents and all other fluorescent bulbs contain small amounts of mercury, which can cause brain damage.
When broken, fluorescent bulbs release mercury vapors into the air that could pose health threats, particularly to small children.Studies have shown that even low levels of mercury can be extremely toxic. Babies who were exposed to even tiny doses of mercury before birth can have slower reflexes, speech problems, and even autism.
Concerns about compact fluorescent bulbs circulated on the internet after a woman from Maine was told she needed to hire a specialist to clean up mercury dust released when she dropped a compact fluorescent bulb on her daughter’s bedroom floor. The clean up was estimated to cost $2,000 and was not covered by insurance.
Another Cause are Christmas Lights. These fluorescent bulbs that look so pretty on Christmas, can make this your worst holiday to live through. Christmas trees were the items first ignited in an estimated average of 300 reported U.S. home structure fires per year in 2000-2004. These fires caused an average of 14 civilian deaths, 21 civilian injuries, and $16.8 million in direct property damage per year. These statistics include both real and artificial trees. On average, one in every 22 reported home Christmas tree fires resulted in a death. More than four of every ten home Christmas tree fires are caused by electrical problems or malfunctions. One in four (24%) home Christmas tree fires resulted from a heat source placed too close to the tree.
Six percent were started by children playing with fire. Holiday lights (or other decorative lighting with live voltage) were involved in 16% of the home Christmas tree structure fires. Fixed or portable space heaters were involved in 6% of these incidents. No equipment was involved in 47% of these fires. Candles were the heat source in 12% of the home Christmas tree fires per year between 2000 and 2004. Two-thirds of the home Christmas tree fires were reported in December, 20% were reported in January. During the same five-year period, 80 outside or unclassified fires began with Christmas trees, on average, per year. Two-thirds of these fires were intentionally set. Fifty-four percent of the outside and unclassified home Christmas tree fires occurred in January.
When a light bulb of a Christmas tree breaks, you might as well throw away all of the lights. The wire inside of the Christmas tree lights can easily melt and cause an electrical charge throughout the other lights, causing a fire. Also, you have to be careful where you plug in your lights and your trees should always be wet enough because if it does catch on fire, it will not burst into flames so quickly. There is also a negative to that because if your lights cause a spark from the outlet and touches the tree, wet or not, your trees will still catch on fire. Lights are also containing Lead, which prevents fires from starting, but can cause harm to your body.These are the good and bad of Neon Lights.
