I will have a similar pondering ahead of me. I have hesitated with lighting so far...
But looking at your portside light it simply looks so good! I'm certain to install lights, now.
I don't remember, what gow stands for, but if it is so bright in light, isn't it going to be very bright in dark? It may be a thing with the camera/photo that makes it seem brighter than in reality?
Otherwise - can you dim a gow with a resistor?
