A 100W incandescent bulb produces about twice the heat and light of a 50W incandescent bulb. A 50W fluorescent bulb produces less heat and much more light than a 50W incandescent bulb. It is much more efficient at producing light.

Yes. practically all of the input into a light bulb is turned into heat.
The higher the power consumption. The greater the heat loss. The brighter the light.
A 50 watt light bulb will produce 50 watts of heat. The light that it gives out will change into heat when it is absorbed by the surroundings. Any of the input that does not produce light will generate radiant heat..

Yes. Two different watt levels produce two different levels of heat and, consequently, light.

Heat is related to the temperature of the filament in an incandescent light bulb. And, interestingly, the color of the light is related to the heat. Low heat tends to produce orange or red light; high heat tends to produce more bluish light.

Heat is a measure of energy expended. Higher wattage means more energy is expended in creating the heat, which in turn gives us the light we are looking for. Although watts are typical measures for light bulbs, energy expended in a house is usually measured in kilowatts; meaning thousand watts.

Fluorescent lights produce about the same amount of light as incandescent lights, but using 1/4 the wattage for the same illumination. This is why people are switching to fluorescent lights given the high price of electricity nowadays. Flourescent lights use a technology that does not use heat to create the light.

yes. the higher the wattage of the light bulb-the higher the temperature
