I have a HLG Scorpion Diablo I am testing with the Pulse Pro. I have attached a photo of the advertised spectrum and actual spectral readings.
I expected it to be off a little, but it is missing a big chunk of red at 660 compared to what is advertised. On a side note, I did not buy this to measure spectrum, and I am super happy with my purchase even if it didn’t measure spectrum at all, but if it it has the feature, I am gonna play with it.
So i guess my question is, what kind of accuracy can be expected for spectrum readings?
