I used to have a 2x39 watt Nova Extreme HO (36") over my 46 gallon bowfront. I would consider what I had as low light. the aquarium is rather tall for that light so, I couldn't grow glosso or HC very well. I replaced the light with a 4x39 watt Nova Extreme (156 watt) and that tends to be high. I run 2 bulbs for 8 hours with all 4 bulbs running 4 of the 8 hours. If I run all 4 bulbs for the whole lighting period, I have scrape GDA to often so I went with noon burst period that I run now.

Maybe more of an answer than you were looking for, but sometimes, saying high or low is too subjective to answer yes or no.
