No worries on not having the PAR chart. I'm currently putting together a standard 10 gallon that I'll use as an observation/staging tank for fish and corals before they go into either my 40 gallon mixed reef or 150 FOWLR. I previously had the tank bare bottom with just PVC in it in my office but my wife wants to display it so I built a stand and will be adding live sand/rock and now need a better light. I run AI Prime HDs on the 40 gallon which will be across from this in the same open living space so I'd like to be able to reach similar spectrum. The 10 gallon will house the next fish for my other tanks (no permanent residents) and will have just a few softies and easy LPS frags. I see Premium Aquatics has the Aqua Knight for just $50 now. If you had to do it again, are you happy with the Lumini marine or would you try the Aqua Knight? Programmability doesn't matter too much as I'd like to be able to set color/intensity and just have it on a timed outlet. Thanks in advance!
