Device for measuring light intensity
WebThe CIE has recommended in CIE 127 that LEDs be measured using 2° and 6.5° geometry, and that these two readings are averaged to yield "Averaged LED Intensity." A typical LED receptor is a tube in which one end is attached to the light measuring device and the other end receives the LED. WebHowever, what matters most in terms of measuring light intensity is the number of lumens falling on a surface, which is expressed as lux. So …
