Yes... but very little.

LEDs are light emitting diodes. They consist of a semiconductor junction that consumes electrical energy to efficiently produce light. This is in contrast to Tungsten lightbulbs which pass Electricity through a tungsten filament and produce light but waste a lot of the energy as heat.

LEDs only convert energy from the electrical form to light and not produce it. The only way energy is produced is when mass converts to energy like in a nuclear reaction, or on a small scale when something burns. Read up on Mass energy equivalence at http://en.wikipedia.org/wiki/Mass-energy_equivalen... . It is a fascinating topic.

Converting light to electricity would be a photodiode, and not an LED. This device generates an electrical signal whose magnitude is in some way related to the intensity of light of a certain wavelength falling on it. This is more of a detection device than an efficient energy converter. An efficient device that converts light to electricity for use is called a photovoltaic cell.

We've got nothing as of now that can produce more energy than it takes in, so no. However, certain wavelengths of light can knock electrons around on metals, so that might be where the confusion comes from. Maybe some LED lights do that, I don't really know.

LED lights transform energy. They take electrical energy and transform it into light. They can go the other way around and be used as a photo detector, but you get very little electrictity out of them.

There are some other things that work both ways. For instance, some thermoelectric materials that can convert "heat on one side/cold on the other" to electricity, or convert electricity into "heat on one side/cold on the other". The US government is looking at using the material to assist with battery charging on trucks (you wrap it around the muffler and get electricity), and it is used in some solid-state refrigerators and computer chip coolers (apply electricity and you cool your chip).

Yes they produce energy, in the form of light and heat.

Do they use light and create electricity, no.

.

Energy cannot be created nor destroyed.

Always remember the above.

LEDs convert electrical energy into light (and heat) energy, they do not creat energy or electricity.

All I know is that LED lights use LESS energy than other lights.

LED stands for light emitting diode, and they can't convert light to electricity, for that you need solar (or photovoltaic) cell

all lights are energy along with sound and various other stuff

No, that's backwards. They consume electricity but not much.
