How do you prove that it is the wattage and not the physical size of a light bulb that matters for energy use?

Energy use is measured in watts. The watts used by a light bulb is on the package or the bulb. Find bulbs with the same wattage but different physical sizes if you want to prove this.

When you leave your lights on when you are not home how much electricity do you waste?
What ever the wattage rating stated on the light is, this is the amount of energy you are using.
What affect does the amount of light have on photosynthesis?
It depends on light. it is changing with light.
Do flood lights use more energy?
No, flood lights do not use more energy. If the wattage is the same between a flood and a spot light, it is the wattage used that you pay for. It is the lens of the bulb that determines the light output pattern. A smooth surface will give a flood pattern where as a spot has a lens that focuses the light into a central location. A reflector flood has a silvered interior to direct the light outwards on to an object.
What is the brightest white light bulb?
There are bulbs that are designed to be bright.ÊThe wattage of a bulb does not tell how bright it is but is tells the amount of energy it uses.
Does the wattage of a light bulb effect the amount of heat given off?
Power is a measure of the rate of energy consumption, or the rate of doing work, or the rate of heat transfer, expressed in joules per second which, in SI, is given the special name: the watt. A lamp's wattage, therefore, indicates the rate at which it is using energy.
Does light intensity affect electrical energy?
The more electrical energy there is there is more power or wattage which means that the light intensity is higher if there is more electrical energy.
How does a light bulb's wattage affect the heat detected above a light?
the higher the wattage is the hotter it gets
Why Candleabra based light bulbs in new fans?
so you consume less energy. the highest wattage is 60 on candleabra.

Are there any table lamps out there that only take energy efficient light bulbs?
I have not ever seen a table lamp that only requires a energy effcient light bulb. Usually all lamps will accept any light bulb regardless or energy wattage or usuage.

Do the same wattage candelabra and incandescent bulbs draw the same power?
Yes, wattage is wattage, is wattage, is wattage. "Power" is calculated in wattage. It equals the voltage times the current in amps. In a light bulb, the resistive filament will cause a certain amount if current to flow making the filament hot and producing light.

What are characteristics of light energy?
The characteristics of light energy are as follows: light travels at 300,000 km/s, light exerts a physical pressure on objects in its path.
