Review on JBJ Nano Refugium Light Aquarium by Tiffy Andreani

I bought this flashlight in January 2015. I use it as a shelter in my reef tank sump. The light works well and keeps my macro algae healthy. Even coral algae grow there. The problem is that after 9 months one of the lamps went out, and the brightness of the other three lamps decreased significantly. I would rate this device 5 stars if it weren't for this issue.
