The amount of light produced and the amount of power consumed. A watt is a unit of power and electrical power is determined using the formula: P = I2*R , Where P is power, I is amps and R is resistance. But using Ohm's law ( V = I * R) the following can be obtained: P = V2/R , Where V is voltage. In US house holds the standard voltage is ~120V, changing the resistance of the filament of the light bulb will change the amount of power consumed and therefore the amount of light produced. The higher the wattage the lower the resistance of the filament. Filaments are used in standard incandescent light bulbs and not in fluorescent tubes or LED fixtures.

What is the minimum watt of a light bulb for night reading?
40 watt light bulb. This is obvious. Go do an experiment. -_-
Can you use a 50 watt halogen bulb for a 100 watt halogen bulb?
Yes. It just won't be as bright.
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
What is the volt of a zero watt bulb?
120 volts.
What is the voltage drop on a 220 watt bulb?
To answer this question the systems voltage on the bulb must be known.
What does the difference between 60-watt and a 100-watt light bulb describe?
power difference
What it is the difference between 100 watts and 75 watt light bulb?
25 watts?
If you increase the number of watts in a light bulb will the amount of radiation it produces increase too?
If you are talking about light radiation then the answer is yes. You can see the difference between a 40 watt bulb and a 100 watt bulb just by looking at them.
Is looking at a laser more dangerous than looking at a light-bulb of the same intensity?
Yes. There is a huge difference between a 1-watt laser and a 1-watt light bulb. A 1-watt laser will burn a hole in your eye.

What does the difference between between a 60-watt and a 100-watt light bulb describe?
Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.

Compare and contrast a 60 watt and 100 watt light 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)
What is the difference between the energy saving light bulb and the filament bulb?
Energy saving bulbs (typically LEDs) provide higher lumens per watt compared to filament lamps.
Can A 70 watt metal halide bulb be replaced with A 150 watt halide bulb?
No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
