JUNOLUX LED Flickering Light Flame Bulb The JUNOLOUX LED frame light is the perfect option if you want to try out a frame bulb for the first time. The calculation of the FI is done by the expression: Where: A – value of the area under the run to the mean value, B – value of the area below the mean value. Like Translate. There is one more method of measuring the flickering led effect value, it is called SVM (stroboscopic visibility measure). Quality LED lighting manufacturers are eager to take measurements of the brightness of their LED luminaires because of the desire to communicate this knowledge to their customers. I know what they do, i just cant understand how they do. Related searches. Translate.
