I'm still considering options for a 10 foot aquarium I will be setting up next spring. Two brings I've run across are GHL and Orphek which do not seem to be that common in USA and so I wanted to ask if anyone has experience with either or both lights and if so can provide some feed back; esp comparison with onf flat; wrgb 2 or fluval 3.0 would be welcomed. I'm aware that at least the ghl is not cheap but not sure if it is a quality light for a well planted aquarium and provides a nice look with good colour balance.
