from its power if it is 100 watt so it produces 100 joule per second but this includes all energy produced by the lamp (light/heat energy)
Their is a formula E=h x v, E=energy, v=frequency, and h=the constant I think
Look at the watt rating printed on the bulb, then multiply by the number of hours it runs for, the answer is the energy in watt-hours.
They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.

An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
mechanical to electrical to light energy
You should be able to read the power off the bulb or its packaging.
The light-bulb will probably burn out if you connect it directly. Other than that, you CAN'T calculate the time duration based on the data provided. The duration depends on how much energy the light-bulb uses, and how much energy the batter is able to store. Voltage is NOT a unit of energy.
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
About 2 %.

What are the uses of Heat energy
A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.

An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
