I have three Sol Blue modules over my 180g. This morning before I left for work, I notice that the lighting under one of the modules seemed different than the other two. At that time of the day, the settings are W0, B0, RB2. When I opened the canopy, two of the modules clearly had the RB leds lit. However, on the third module, the B leds were lit. The strange thing is that the same row of LEDs were lit on all three modules. In other words, the inner most row of LEDs on all the modules were lit. However, on two of them, the inner rows were RB and on the third it was B. Anyone experience this or know wht the problem might be?
