Are regular light bulbs or fluorescent bulbs worse for the environment?
On the one hand, fluorescent bulbs contain toxic materials that can be released when the bulb is dumped. On the other hand, fluorescent bulbs last so much longer than do regular, or incandescent, bulbs that this problem is minimised. More importanlty, fluorescent bulbs use only about one-fifth the electricity of incandescent bulbs, thus helping us to reduce our greenhouse gas emissions and therefore slow down global warming. Since global warming is by far the greatest environmental danger we face, fluorescent bulbs must be better for the environment.
What do light bulbs do?
They use less energy to produce light, and thus save energy and help to save the environment through conserving electricity. The energy efficient light bulb applies fluorescent lighting technology to replace incandescent lighting technology. In the latter, a filament is heated past red hot to white hot to emit useful light. This creates a lot of heat, and is inefficient. The fluorescent tube screws into a socket just like the incandescent lamp, but has electronic circuitry built in to supply the elevated voltages necessary to operate the coiled fluorescent tube. Inside that tube is a gas mixture that is ionized by the voltage, and the ionized gas emits useful light. This process is much more energy efficient than incandescent technology.
Can faulty electrical wiring cause light bulbs to burn out quicker?
If light bulbs are burning out quickly the light fixture could be getting too much electricity due to faulty wiring. They could also burn out due to a loose wire or screwing the light bulb in too tight.
What is a lumen How does it relate to watts?
A lumen is a unit of luminous flux, which is the amount of light emitted per unit time. A watt is a unit of power (such as electrical power), which is the amount of energy consumed per unit time. Light bulbs have ratings in watts, which measures how much electricity they use, and lumens, which measures how much light they give off. For the same kind of bulb (incandescent, fluorescent, LED, etc.), a bulb with a higher wattage will produce more lumens. However, a 10-watt LED or compact fluorescent bulb may produce more lumens than a 40-watt incandescent bulb.
What are the most efficient light bulbs?
At present there are several types of light bulbs available for indoor domestic use.Arranged by their efficiency from least-to-most they are:Incandescent bulbs (60 watts)The old style light bulb emitting light from a hot filamentFluorescent tubes (30 to 40 watts)Several inch to several foot long tubes emitting light from a vacuum with a trace of Mercury vapour requiring a special fixtureCompact Fluorescent bulbs (15 watts)Roughly incandescent sized small fluorescent tubes designed to screw into standard light bulb fixturesLight Emitting Diode /LED's (5 watts)Small cool running lights using special mini-sockets or designed to fit into conventional sockets.Notes:Power requirements to provide as much light as a 60 watt incandescent bulb indicated in parenthesesBoth types of fluorescent tubes contain mercury and require special handling and disposal requirementsOutdoor lights would also include Mercury and Sodium vapour bulbs as well as high powered incandescent bulbs. These are more efficient than incandescent bulbs but the colour spectrum emitted and other aspects makes indoor use unlikely
How much is a fluorescent bulb?
fluorescent light bulbs are usually from 9$-15$.
What is it that normal light bulbs give off much more than fluorescent light bulbs?
Heat.
How much percent of the worlds electricity is from light bulbs?
None. Light bulbs use electricity, they do not create electricity.
Lower Your Electricity Bill Just by Changing Your Light Bulbs?
Most people light their home using incandescent light bulbs. While these bulbs may seem less expensive, they can add quite a bit of money to your electricity bill. To lower your electricity bill, swap your incandescent bulbs for compact fluorescent lamps, or CPL's. CPL's are a type of bulb that uses 75% less electricity than incandescent light bulbs. Just by switching the type of light bulb you use, you can quickly lower your electricity bill. These bulbs also last much longer than regular bulbs. Most CPL's last around ten years, which means that you will enjoy a lower electricity bill, while never having to change a bulb.
How much electricity needed for 100 watt compact fluorescent lamp?
The answer is simply100 Watts. The Wattage rating of electric light bulbs is just the amount of electricity they consume. So a 60 Watt bulb would take 60 Watts of electricity. In fact, if you could buy a 100 Watt CFL, it would have the light output equivalent to about eight 100 Watt conventional (incandescent) light bulbs.
Where is there a resister in a light bulb circuit?
In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

How many times do you need to replace energy efficient fluorescent light bulbs?
comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
Do fluorescent bulbs get hot?
Yes but not as much as incandiscent bulbs

Why are LED bulbs considered to be better at saving energy than compact fluorescent ones?
LED bulbs, or Light Emitting Diode bulbs are far more efficient at turning energy into light than fluorescent bulbs. They are the most energy efficient bulbs available today and last much longer than any other bulbs. Although very expensive, the price is expected to come down over time.
Do incandescent light bulbs have more mercury in them than fluorescent?
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.
