I ran galaxyhydro for a while and they are for sure decent lights. I would strongly urge you to try SB reef lights once you get more into the coral game. You can just buy a replacement board that works on your galaxyhydro or get a SB reef light and rub it beside your GH and you will really be able to see the difference.
This is the completed setup, I'm just glad i don't see the lights from outside the house anymore
