Now I know how much PRA the light is using
-light for the plant tank
-light low =? PRA
-light medium =? PRA
-high light =? PRA

Good questions!

Assuming you measure your PAR at the bottom of your tank, here are the general value-ranges in those 3 categories:

- Low light: 40 PAR or less
- Medium light: 40-60 PAR
- High light: 60 or more


I hope this helps! In my case, I am in the medium-high range with around 60-65 PAR at the bottom.
