Every once in a while, you will get a dud, but for the most part they are intended to last for up to 10,000 hours. For comparable Lumens, they save about 75% of the energy tha…t a regular filament based incandescent (the regular kind) will use. Even with the duds, it saves you significant amounts of energy. Get a good bulb, though. You're going to want to like the light quality and a good bulb will last longer. You will save money even if they're giving away the incandescents. Ideal conditions for a compact fluorescent bulb (CFL) are when the bulb comes on, has a chance to warm up, and then stays on. Closet lights will burn out sooner (per hour of use, but since they're used so less frequently), but you will still save energy. Modern bulbs come on instantly, but they take about 30 seconds to heat up. Best of luck!
A fluorescent light bulb is filled with argon gas and mercury vapor. Electricity is passed between two naked contact points within the tube. This super heats the mercury v…apour turning it into a plasma. this in turn gives off invisible UV light. The glass of the bulb is coated with a phosphor which fluoresces in the presence of UV light. This in turn produces visible light.
i shouldn't think so.... it would be MAGIC.
The US Environmental Protection Agency provides information on mercury released from a break and how to clean it up as safely as possible.
In lighting, the lifespan of a light bulb is often referred to as a life hour rating. Generally speaking, CFLs last longer than incandescent bulbs. Incandescent bulbs last fro…m 1,000 - 2,000hrs whereas CFLs last 3,000-15,000hrs or more.
Fluorescent bulbs tend to last longer.
in a compact flourescent about 8mg.
There is the an electronic circuit with a lot of Diode, Capacitor, Resistance and many other components, which use to make the bulb more efficient and help to save the energy…. Because in regular bulb there is only a wire which is directly connect to the supply that's why the resistance is high and this is the cause of energy wasting, so we use the electronic circuit to save the electrical energy and to make a high efficiency devices.
Yes, an incandescent bulb uses more energy than a fluorescent bulb and a fluorescent light bulb lasts about 10 times longer.
These light bulbs are better because they last 10 times longer and use 75% electricity
they can be good, but they can be very harmful to your health because of the mercury in them. so you cannot throw them away in regular trash cans.
I would say no. My reasoning is that if incandescent bulbs have as much or more mercury than fluorescent bulbs, the fluorescent industry would be debunking all the reports of …a mercury problem. Incandescent lights do not need or use mercury to operate, so there is none in them. Fluorescent lights cannot be made at all without mercury, as it is the glow of mercury ions that produces the UV light inside the fluorescent bulb to excite the phosphor coating to make visible light.
A compact fluorescent lamp (CFL) uses electrical current to vaporize a small amount of mercury, that in turn, excites a phosphorous coating on the inside of its tubing. This p…rocess allows almost 75% of the energy consumption to be converted to visible light. In contrast, an incandescent lamp passes current through a resistive filament that heats to the point of emitting light. This process spends almost 90% of the energy consumed producing heat, with the remainder left over for it's intended purpose.
all lamps (light bulbs), are manufactured to strict standards of safety, there are not set rules as to which is more dangerous than the other, they have differing variables th…at affect saftey in different ways. For instance fluorescent lamps contain harmful gases which is why they have to be disposed of safely. Incandescent lamps have been known to explode (I have seen it happen), but that is rare and is normally due to cheap light fittings and fluctuations in the voltage of the supply. Obviously they have the same level of danger in terms of the glass, and of course in terms of the heat, the closer you get to the base of a fluorescent (the points of contact to electricity), the hotter they are. Other than those items, there is very little difference between them in terms of danger.
Fluorescent bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in th…e bulb.
One may purchase a fluorescent light bulb at Home Depot, Lowe's and Home Hardware. Other sources for these bulbs include Canadian Tire, Rona and Walmart.
Fluorescent light bulbs can be bought at most hardware stores and lighting specialist stores. They can be purchased online from these stores and from online Dealers such as Am…azon. A limited variety of fluorescent bulbs can also be purchase at high street department stores and supermarkets.
