I am lighting my tank with two large skylights. Here in NE Ohio, there is quite a difference in the sun's intensity from summer to winter. I have blue shade cloth for the summer https://www.gothicarchgreenhouses.com/chromatinet-blue-shade-cloth.htm and 50W, 450nm dimmable LEDs for the winter.
Today when the sun was at its zenith, I got a reading of about 4400 lux on the rock where the coral will live. Is there any way a lux meter can help determine how intense the LEDs should be and how much shade cloth to use? My goal is fairly uniform light intensity.
I hope you can take a look @saltyfilmfolks. I saw the thread about using lux meters as a substitute for PAR meters but there was nothing about natural light.
