James.lope | "Pure white light bulbs give off the most light..."
Pure white light bulbs give off the most light. This id due to the fact that pure white light contains all the colors which help to give off the most light. Other bulbs like yellow ones follow the white ones. But the most recommended light bulbs are the white light bulbs giving most light.

 Q. How to make a light bulb light with a switch and no electric plug-in ? alright so i have to make those tiny light bulbs like you know christmas lights.. light up. problem is i have no electric power that can be used. so i need to somehow use a switch so i can easily turn it on and off and the lights have to go around a square border. please help asap. please tell me which materials needed and obviously how to do it! thanks!
Go to google, type in "battery powered christmas lights," and hit the search button.
I think you will find what you are looking for.

Q. Can a person use a black light light bulb for a night light for a leopard gecko? i have 2 full grown leopard geckos, i have a day light bulb in there aquarium but i don't have a night light, so i wondering if i could use a black light light bulb for a night light for them?
"Be careful with the kind of black light you buy..."
be careful with the kind of black light you buy. most of them heat up wayyy to quickly and smell like they are burning, many cases they can melt their holder, even if they are of low watt. id recommend using a red light bulb, by flukers, the reps cant see it, but you can see them. and it will give them adequate heat. geckos dont like sudden drops in temperature, they get really stressed from that and can loose their color.

Q. How does a light bulb light up and emit different colour when it is heated in a microwave? how does a light bulb light up and emit different colour when it is heated in a microwave? another question is how does it emit different colours? it first glowed green, and then purple. how is the explanation behind this phenomena?
"Too sure but out of guessing the light is due to the energy frequency..."
Not too sure but out of guessing The light is due to the energy frequency being channeled in the lightbulb from the radiation. More energy leads to different colors....
Im not that sure but the colors follow through
ROYGBIV
Red Orange Yellow Green Blue Indigo Violet
Low----------------------Medium---------------High
The light itself is shown by energy channeling through something called a filament(Im not sure what its called).
Just my guess

Q. Why would an inductor delay the time of light bulb lighting? well, i saw in the internet that having an inductor in the circuit would cause the light bulb to light up slower. but i could not find the reason of that happening.
why does an inductor delay the current flow? and why does this happen only when a magnetic thing is put in the coils?
An inductor is, as a mechanical analogy, "electrical inertia".
As a hydraulic analogy, think of a paddle-wheel of high rotational inertia mounted such that some of its paddles are struck by the flow of water. It is hard to speed up the paddle-wheel, but once it is going, it pushes the current against stopping such that it steadies out the current.
Inductors first have a voltage applied across them, and it takes time for a current to begin flowing through the inductor. Hence the inductor has inertia.
Also, there doesn't need to be a "magnetic thing" put in the coils for it to be an inductor. Any coil of wire is an inductor.
The virgin magnetic material (un-magnetized initially) placed in the core of the inductor simply serves the purpose of designing an inductor with a higher value of inductance than if the core were simply air.

Q. How can i make a light bulb light up? i have a science project for school and my friend are wondering how to make a light bulb light up. there will be a lid, and when it opens we want the light bulb to light up.
"To the battery and watch your bulb light up!..."
Materials you will need to make a bulb
• One small jar
• Cork stopper for a lid
• A 1-inch nail
• Three feet of shielded copper wire
• One 6-volt battery--not a car battery!
• Thin iron wire (the best source for this is unraveled picture hanging wire)
Materials you will need to record your results
IMPORTANT SAFETY HINTS:
(1) This experiment needs to be done with an adult present and supervising it! (2) Always wear safety glasses and gloves when doing experiments! (3) Be careful handling the filaments when they burn out--they will be HOT! (4) Never play with wall sockets or household electric currents.
Procedure
1. Print your "Record my results" form. You will need it to record the results of your experiment.
2. First cut the copper wire into two lengths about 1-1/2 feet long. Cut off an inch of the shielding (plastic coating) at each end of the strands.
3. With a nail, drill two holes into the cork. Push the wire through the holes in the cork so that about two inches of the wire can be seen in the jar.
4. Make a hook at the end of the copper wires so that you can twist small strands of iron wire around them to make a filament.
5. Twist several strands of iron wire together and stretch them across the gap between the two copper hooks to form the filament.
6. Put cork stopper with filament inside the jar.
7. Carefully hook up both copper wire ends to the battery and watch your bulb light up!

Q. I have a 1978 toyota corolla se. when i turn on my lights both eliments in tail light bulb light up. ? when i apply the brakes both of the elements in the brake light bulb light up. one element is for the brakes the other is for the tail lights. what could the problem be?
It could be a couple of things. First thing I would look for would be a ground problem. Check the wiring and ensure you have a proper ground. If everything checks out find I would guess you have a bad headlight switch.

Q. What's the name of the type of light-bulb that plugs in a socket rather than the regular screw in type? hello,
we have an external light for lighting up our porch. the cover is roughly 9"x4"x4" that 4 screws hold in place. when the light burned out, i found that the type of light-bulb it uses is the type that plugs in. the bulb in question has 2 little prongs about 1/4" long at roughly at the 2 & 8 o'clock positions.
what type of light-bulb is it?
thanks.

they may be 2 pin bulbs, mini flourescents, but I dont think bayonet heres the link

Q. Why does sugar and water make the light bulb light? in our class we did an experiment where we stuck a light bulb with what i think was a conductor with two tubes attached and stuck it in various solutions. one of them was sugar and water. it wasn't as good as nacl but it did partly light the bulb. i tried researching the reason but all the claims were that sugar dissolved in water doesn't conduct electricity. i need if help if anyone knows if it does in the first place and why.
"Why did the light bulb light..."
Well, water itself typically conducts electricity because of the small amount of ionic impurities that're typically in it. So, it's not surprising that it still conducts even when you add some sugar.
Why did the light bulb light?
That depends - what conductors were connected to the light bulb?
My guess is that the sugar water specifically, or the NaCl, has nothing to do with it.
If you take two wires made of different metals, and connect them on one end with each other, and on the other with an aqeous solution of basically anything (such as plain water, with its impurities, or plain water with sugar in it, or salt water) between them, an electrochemical reaction will occur. One of the metals will get "reduced" in the solution, and the other will get "oxydized". The result is a net movement of electric charges moving between them, and that's an electric current.
If you put, say, a light bulb in between the metals, instead of connecting them directly to each other, the light bulb will light up because of the electric current.
When you use something like that to generate electrical power, it's called a "galvanic cell".
http://en.wikipedia.org/wiki/Galvanic_cell
The illustration in that article shows the use of a salt bridge, but that isn't strictly necessary.

Q. How to light a bulb without a switch? hello, i was just curious how to light a light bulb without using a switch.
for example: like a mouse running on a wheel to light it up. i was wondering how this worked?
or even water lighting up a bulb.
thanks.
"To light a bulb..."
The switch just stops or starts current flow. To light a bulb, you will need a source of electrical current, which may or may not have a switch in the circuit. So you are looking for an unusual way to generate current. The most common ways are to use the electrons from a chemical reaction (the dry cell), or to interact magnetic fields (the electrical generator). If this is a science experiment, then a mouse running on a wheel will turn the generator to light the bulb. Or water revolving a wheel can also turn the generator. So can wind -- but all of these ways are already long in use. A more unusual way is to drop sand or dirt in a stream on an overshot (cups for water) wheel. Or you could set up a spring-driven system to drive the generator. It all boils down to making a source of elecrical current to drive an electric generator. Or you could explore other ways to make a dry cell.
