The amount of light coming from a source is measured in Lumens and a common way of measuring this quantity is in foot-candles . Led light starts at an intensity of around 0.1fc and can go up to 2,000fc. So how do you measure led light intensity? Well, the easiest way is to use the Flux method. Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are.
