What’s the a ,b , and c modes mean
The modes allow for control of the light's spectrums. The light groups the various spectrums into reds (A channel), Blues (B channel) and Whites (C channel).
Awesome light and trim leaf is great to do business with.
I needed a light that could be used for the whole growth cycle for my various herbs... Lowered my power bill with the timer function! Just make sure you guys check your LED temps and you're set.
