Aquarium Advice FINatic
I don't have LEDs to replace my grow tank t5ho's yet, but now that the price has come down tremendously it's becoming more feasible to do so. Instead of replacing bulbs this year (I have 14 bulbs to replace) I'll probably just get a few fixtures.
Is the RayII and/or planted+ (i think that's the name) comparable to a 2 bulb t5ho as far as PAR goes?
Have you seen this thread on the planted forum? It has a chart which shows PAR for most common lights: Lighting an Aquarium with PAR instead of Watts
I think you can compare the two you mention here.
