I have the 36" version of this led fixture from Beamswork. 2410 lumens it says, 10000K leds with some blue leds for lunar, it's called Hi-Lumen TRI 90 in my case. I did buy it in Canada.
My tank is new, 36" X 18" X 24", I was worried it would not be enough because my tank is tall, 24".
It's there since january 5th, getting great growth overall. I am happily surprised, lighting 11,5 hours a day. Crypts, egeria densa, hygrophila polysperma, bolbitis, microsorum, limmophila sessiflora all of them are growing.
I guess it's low light.
