We'd happily answer if we had any idea WTF you were talking about.\n\nSlow down, think about what ytou mean, and write in complete English sentences usnig normal grammar. Explain what information you actualy want. Try showing some courtesy to others by being considerate and taking the time to communicate.\n\nPosting the same menaingless gibberish 4 times is a waste of perfectly good electrons.

Electric light is produced by running an electric current through a resistor that then glows white-hot.  Edison searched through thousands of different materials to find one that glows just right.\n\nToday most regular light bulbs use a tungsten filament (a little wire made of the material 'tungsten') which gives off a lot of light but it is relatively breakable.\n\nWhen a bulb 'burns out' it means that this little filament has burned up or broken.  It is more likely to break when it is turned on.  Technically I suppose you could get more life out of a bulb by leaving it on all the time but that would be a waste of energy and you don't want light all the time.\n\nThese days there are other materials and other ways to make light bulbs that last a lot longer but they are not in common usage yet.

Turn on one light bulb and leave it on for a while. Turn it off\nTurn on a second light bulb and leave it on. Go up stairs.\nThe second switch obviously turns on the bulb that is on.\nThe first switch (you turned on then off) is for the lightbulb that is NOT ON but is warm from being used. \nThe  3rd switch obviously is the one for the unlit lightbulb that's cold.

NO.  When the lightbulb burns out the filament breaks.  The filament is what the electricity flows through to create light.  When this breaks there is no path for current to flow, therfore no electricity is used.

It's impossible to say considering you give no indication of your lighting needs.\n\nThey do make fourescent bulbs which fit into regular incandescent sockets.  The flourescent bulbs use a lot less energy.

1. A battery lighting up a filament bulb.\n\n2. Use LM317 IC to build a constant current source.\n(http://www.uoguelph.ca/~antoon/gadgets/sccs.htm)\n\n3. Battery Charger

This gives a detailed explanation of how they work.\n\nhttp://en.wikipedia.org/wiki/Bubble_light

You can, but there is a danger of overheating and fire. Here's why.\n\nThe power of a light bulb in watts is determined by the equation P=V^2/R where V = voltage and R = resistance. The higher power (higher wattage) light bulbs actually have lower resistance, so they draw more current.\n\nThat same current must pass through the wires, socket, etc. These also have resistance. The greater the current that passes through the wire, socket, etc. generates heat from the equation P = I^2 * R.  So, if the current is doubled, there is 4 times as much heat that is generated by the wires, socket, etc.\n\nSockets and wires have different ratings depending on their ability to handle high current and heat. You may have seen ceramic light sockets - they provide better heat resistance that lightweight sockets with plastic that can melt.

b/c a constant amt. of electricity is going into it, and it will only get brighter if you add more electricity to it, or get a brighter bulb!

I would probably use Light Emiting Diodes connected to a low voltage dc source using very small gauge twin-lead wire.

Light bulb uses light waves.

THomas Edison invented the light bulb.

what kind of lights? if it is a incandescent bulbs/lamps it can be controlled through an electronic sequencer, you can buy it at any electronic shops near you... if it is a flourescent light, the light might be damaged by using sequencer... if it is metal halide lamps use dimmer instead...

1.First of all it is cheaper then the standard  lightbulb. I use it all the time instead of the standard filament bulbs that use the wire to heat up. \n\n2. It uses your power (electricity) to move Mercury vapor in argon or neon.\n\n3.  Did you know that that type of light does not stay on steady? It makes many many  blinks too fast for your eye to catch. I tried experimenting with using  a "fan". Only way to fully see the  blinks very well is when it is reaching end of its life.\n\n4. A modified version you could use to grow  plants. But it is not your standard "flourescent" light.\n\nYou could try (likely) to check howstuffworks because if I would explain would run out of space.\n\nWord of caution as always: Never attempt to open one flourescent up it will explode. It will release  Gas and could be more dangerous if you  break it near yourself then a standard  bulb!\n\nI LOVE IT we have brains on Q /A today!  Now  that could be used on the message boards too.

Something involving atomic spectra.  For example see\nhttp://www.fas.harvard.edu/~scdiroff/lds/QuantumRelativity/StreetLampSpectra/StreetLampSpectra.html

Two- one to change it, the other one to scratch its bottom. :-)\n\nHow many economists does it take to screw in a light bulb?\n\nNone. If the light bulb really needed changing, market forces would have already caused it to happen.
