How do you work out lumen's?

To calculate lumens, you need to know the luminous efficacy of the light source in lumens per watt (lm/W) and the power consumption in watts. Multiply the luminous efficacy by the power consumption to get the total lumens produced by the light source. For example, if a 10-watt LED bulb has a luminous efficacy of 80 lm/W, the total lumen output would be 800 lumens (10 watts * 80 lm/W).


What the filament of bulb is broken then it is called?

If the filament of a bulb is broken, it is referred to as a "burnt out" or "blown" bulb. This means that the filament, which is the thin wire inside the bulb that produces light when electricity passes through it, is no longer connected and the bulb cannot function properly.


Compare lumen's per watt in incandescent vs LED?

To determine the answer you need to know the efficacy (luminous flux) of the LED light which may range from 30-90. You can use 60 for an average. Multiply the watts from an incandescent bulb - what you are familiar with - say 40 watts x the LED luminous flux 60 = comparable lumens of about 2400 to see the same brightness.


What has happened when a light bulb has burn out?

it simply means that a wire from the light bulb is joined or connected to the charged plates of the capacitor.resulting to discharged of the capacitor.


What happens when bulb blows?

When a light bulb blows, it means the filament inside the bulb has broken due to wear and tear. This causes the electrical current to stop flowing, resulting in the bulb no longer emitting light. To fix this, you simply need to replace the blown bulb with a new one.

How do you know the efficiency of a light bulb?

The efficiency of a light bulb is typically measured by its luminous efficacy, which is the amount of visible light produced per unit of power consumed. This is usually expressed in lumens per watt. The higher the luminous efficacy, the more efficient the light bulb is at converting electrical energy into visible light.

How do you work out lumen's?

To calculate lumens, you need to know the luminous efficacy of the light source in lumens per watt (lm/W) and the power consumption in watts. Multiply the luminous efficacy by the power consumption to get the total lumens produced by the light source. For example, if a 10-watt LED bulb has a luminous efficacy of 80 lm/W, the total lumen output would be 800 lumens (10 watts * 80 lm/W).


Difference between efficacy and effectiveness?

Efficacy is the capacity to produce an effect. It is these conditions that distinguish efficacy from the related concept of effectiveness, which relates to change under real-life conditions. -- Wikipedia: "efficacy"


What does it mean by writing V and W in a bulb?

V on a light bulb means volts. W means watts.
