How much PAR constitutes low/medium/high light?

Not sure if this applies to everything, but it might help

The light ranges shown above are not what is currently accepted by most people. Low light is around 15-35 micromols, medium is around 40 - 60, and high is more than that. Those are not cast in concrete either - just cast in wax

(low melting point wax)

Those values are at the substrate level. The PAR values higher in the tank will always be higher, usually much higher.

Yea.. I just realized by fully reading through the other thread. Or pretty much everything in your graphs would be low light. Which doesn't really make sense ._.

Interesting how even with a good reflector, vertically mounting a CFL bulb is wayyy better. I would've thought it would be pretty equal.
