I did look at that and while I do appreciated the help, I do not understand chart chart at all.

I simply would liked to hang two PAR38 6500K bulbs from pendants above my rimless 40gal tank 37x15x18 and I just need to know how high.



I'm sure from an enters standpoint all this is great info. But, I think a lot of it is lost on most of the readers.
