Science is..

there basicall the same design as the long strip lights but made smaller.they use less electricity than std bulbs whilst giving of more light for less watts.

Just do some research on how fluorescent lighting and LEDs work.

bottom line is that they lose less energy to heat. In an incandescent bulb, a lot (I believe around 90%) of the electrical energy going into the bulb is lost as heat and only 10% produces light.

and LEDs are simply more efficient and produce less heat.

Energy can neither be created nor destroyed, it can only be converted into another form.

bulbs are putting out lots of light energy and very little heat energy compared to incandescent bulbs so there isn't energy being used for heat which you don't want/need.

And they run cold so no power lost due to heat like a normal light bulb.

LED light bulbs give off directional light, so the light goes where you aim it.

bulbs are closer to the color of daylight which new studies suggest is good for staying alert.

LED light bulbs can be used to replace your standard fluorescent or halogen light bulbs.

bright, white LED light produced by our LED Light Bulbs works especially well for task lighting and reading light.

not only produce light more efficiently, they also have a tiny mirror that reflects light in one direction. A more directed light means less wasted light.

term LED stands for Light Emitting Diode.

electronics relies heavily upon LED light bulbs.

instance, LEDs transmit information from remote controls, are used in traffic lights, digital LED clocks, flashlights, and to form images on jumbo television screens.

light bulbs are miniature bulbs that do not use filaments to produce light. Therefore, the life of an LED is much longer than that of a regular incandescent bulb, because there is no filament to burn out. Incandescent bulbs also tend to be much larger in size due to the filament, which must be housed in a vacuum inside the bulb.

light bulbs last as long as a standard transistor used in modern electronics, and are lit purely by the movement of electrons.

simplicity and long life of the LED make its use very desirable for various technological applications.

light bulbs are housed in a durable plastic rather than glass and perhaps most importantly, are much more efficient. In traditional incandescent bulbs heat is generated when activating the filament to produce light.

causes energy to be wasted on the production of heat rather than the production of light. In order to produce the same amount of light as an LED, an incandescent bulb would have to work even harder.

light bulbs save electricity and lower electric bills. Despite this positive scenario, incandescent bulbs are tailored to home lighting and will continue to be used until affordable, household LED light bulbs are available. At present, LED light bulbs are expensive and recommended for low-light applications such as porch lights or subdued corner-lighting. (An exception are chandelier LED light bulbs, which can produce a brighter glow because there are so many lights working together.) As semiconductor prices have decreased steadily over the past twelve years, the time for affordable, brighter LED bulbs is approaching.

will be offset in the long run by savings in electricity and the lifetime of the bulbs, which is reportedly 30,000-50,000 hours on average.

I don't have the science.

the warnings. Jaysus.

contain Mercury.

China makes them.

US removed Mercury years ago from thermometers.

warnings are to evacuate the room if one is broken.

up the pieces with "Tape". Do not touch with hands. Do not Vacuum.

cleaning small pieces with "Tape". Do not inhale.

of Mercury Poisoning. A post here stated that one exploded.

you EPA.

You Dems. Republicans have been lobbying against them. To no avail.

are all we'll have in a couple years or so.

Sat, 05 Jul 2008 16:22:36 GMT

I'm not sure.

i know is that they are full of mercury and if they fall and break you shouldn't touch them with your bare hands.

should also clean the area thoroughly.

Sat, 05 Jul 2008 16:23:42 GMT

um. yeah.

use 20 watts to produce the same candlepower or 'lumens' as a 60 watt incandescent.

electricity used less money spent.etc. a much more interesting question to me is why would the government mandate a change to a poisonous lightbulb? the c.f.l. is a toxic hazard when broken, as it is full of MERCURY.

does the government want us dead? WHY!

an energy saving bulb use less electricity than a conventional bulb example a energy bulb uses 25 watts of electricity to give the sam amount of light as a 100 watt conventonal bulb energy saving bulbs are either LED( light emmiting diode) or more commonly flourescent which contain gasit takes less electricity to heat the gas giving more light per watt of electricity than a normal light bulb. a watt is a unit of electricity the more watts used the more electricity being used.

on some of your household appliances and you will find out how much each different appliance uses compare your kettle to a television the average kettle uses 2000 watts to 3000 watts or 2 to 3 kilowatts (KW) the average television uses 100 to 150 watts.

this is useful.

The short answer: Plain old incandescent bulbs put out a lot of useless infrared radiation, which produces no light and lots of heat. Florescent bulbs put out similar visible light but without the infrared radiation.

last longer because an internal gas ionize unlike an Edison bulb whose filament literally burns up from the trace amount of oxygen that gets trapped in the bulb during manufacturing.

i dont how they work but they do i have not changed my light bulbs for ages
