yes, more light is always good, but what I was saying is that you have a budget on how much you can spend from wat it looks like, spend way too much on your light could just tight up your spending on everything else. As a vendor, I don't mind my client buy the most expensive product that I have. however, as part of the community, I would rather see people get the balance when purchasing equipments.
Here is a 4 ft tank under 2x 108W LED
(36x3W bridgelux) sorry the pic is really small lol
and here is a 4ft tank under 3x 90W LED
(mix with 5w and 3w CREE)
What you need to becareful with some of the "Taotonic fixtures" like this
when you place right on top of your tank it has lots light
but when it move up a bit and all the light are gone
