At 50 cm above the water surface I would say low... or you mean water collum height is 50 cm than I think it would be moderate or medium
Hi,
here you have teh 120cm model, it's a clue.

With 2 fixtures you can grow HC in lower part of the scape... (it's more a question of uniform distribution i believe)

I think 2 fixtures would be better... at the beggining you can use just one, later on both. And get a dimmer in case you will need to dim a little bit to get more control of the light.The tank is 40cm high so 50cm light to substrate.
50cm of water? or air? or some combination?

Its my mistake about a dimmer, sorryI though they were already dimmable? It seems hinterfeld advocate the use of two to grow HC
I have two 60cm (Chihiro knock offs!!) and one original 30cm Chihiro. The 30cm Chihiro runs very cool if you dim one level below maximum. The 60cm units haven't been tested with water yet but I plan to run then at level 4 (total levels are 6) to get even coverage of a 60x45x45.
Didn't @ShawnMac test the Chihiro PAR as well?
Not at all. I only run my lights for 8 hours at a time though.This topic?
Doesn't the dimmer heat's?
cheers
