How do you measure the flux of the LED fluorescent tube
Luxmeter, only test fluorescent lamp within a certain range of brightness, the open bright daylight lamp, the light meter to the lights, see distance of one meter range to see how much brightness, two meters how many brightness range. And the best way to test the flux is by using the integral sphere, the data is the most reliable,
In theory, it's measurable, and it's actually hard to set up. There are two ways of measuring flux, essentially the same thing 1: the integrating ball is measured by your illuminometer 2: set up the field aperture + your illuminometer + space station to measure by the 4PI () stereo Angle integral. The last time you said you have integral ball and light meter I suggest the first way is feasible. In addition you put not fluorescent lamp it doesn't matter, can be measured in area of block of luminous flux, and finally take the area integral. The results must be less than professional distribution photometer to measure, the standard but the data still have rigorous theory and process support.
No, the illuminometer can only measure illumination. Light flux requires the use of a spectral analyzer plus an integral sphere test. Can go to local lamps and lanterns to inspect department to carry on examination.
