presents a ledstring consisting of 140 RGB leds. With help of a controller one can select many light effects (only red, green or blue, or changing from one color to the other, or flickering etc). The selection “static white” (assumed that all three leds are maximally on) is chosen to do the measurement, this to get the maximum luminous flux.
