I was chatting to a guy in a local marine store about par.he mentioned the photone app as being pretty accurate so I thought I'd give it a try on my normal 23k spectrum
The results if they are to be believed were very low at water surface.i switched to the 15k spectrum & got much higher results.this confuses me as I thought the main power in the led90 came from the blues where 80w of power goes?
This has left me thoroughly confused despite calibrating the app.
Has anyone had similar experiences?
I've added 15k/20k/23k par readings with the app to illustrate
