Just over the summer and really minimally - it was going to be my QT light but the arm doesn't center over the tank and it looks kinda dumb with partial shading over the tank. I don't like it, and don't have any use for a nano light otherwise.
Thanks
Let me think about it, couple of reasons.
I need the mounting bracket for my installation, plus the Black Friday is next month. Kessils go on sale, for probably the same price you are asking, plus warranty.
