That varies a lot, depending on the type of light bulb. The old-fashioned incandescent light bulbs produce much less light, for the same power, than the fluorescent light bulbs.

A 25 watt light bulb consumes 25 watts per hour. Watts are the unit of power, and 1 Watt = the conversion of I joule of energy per second so a 25W lamp is using 25J/s of energy.
Find out the power of the light in watts, and divide by the voltage it runs at. The answer is the current in amps.
To answer this question a voltage needs to be stated. A = Watts/Volts.

5 joules? I'm not sure...
The higher the wattage, the more electrical energy is being used. In a light bulb the electrical energy is converted to EM energy which appears in both visible and infrared parts of the spectrum, so the answer is no, it will be at a higher rate for a 100 watt bulb
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb.
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)
Yes, that is what the numbers mean.
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
A lot
What are the uses of Heat energy
The energy is 95 x 40 watt-seconds (Joules).

120 watt * 36 hr = 4,320 watts

60 x 45 Joules.
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
In the sense of 'work' as force moving through a distance, a light bulb does none of that. But in the sense that mechanical work is equivalent to energy in other realms, the 75-watt light bulb consumes 75 joules of electrical energy every second, and radiates 75 joules per second of energy in the form of light and heat.
