I've been using one of these for the past year and it has been great for me:
I have it in a PVC lamp clamp over the fuge and I have to trim back the growth bi-weekly. I run it 24/7.
I'm setting up a46 gallon display fuge right now. What would you recommend for that?To clarify, that bulb is over my macro fuge... I also have a display fuge connected to my reef system that uses an LED panel, so it depends on what kind of fuge we're talking about. For a macro fuge, that Cree LED bulb has been great for me.
Welp.... a Kessil H150 Magenta is on its way to me.... This post and today pushed me over the edge.
