It describes the power consumption of the two units when they're turned ON
and operating.
It MAY describe the difference in their brightness, and that's the way it's widely
understood, but that's not necessarily true.
light output
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.
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.
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.
40 watts of consumed power. The light output may be greater with one compared to the other, but wattage alone does not give us that information. Electric heaters, for example, consume 1500 watts of power and produce almost no visible light.Check the Lumen's. That is where the difference is.Current draw and light output.A 60 watt bulb uses 60 watts of electricity (i.e. it converts 60 joules of energy per second), a 100 watt bulb converts 100 joules per second. Electrical power is measured in watts. Since a 60 watt bulb pulls less energy to it than a 100 watt bulb the 60 watt bulb will not be as bright.Resistance.Just in the amount of power used and the brightness of the bulb. The 60 watt bulb might be a bit smaller.
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)
