Will it take one or two finnex planted plus 36" over a 40b to be low light?
I mean real low light not just barely lit.

You might want to go with a different light. I have one fugeray over my 40b and I think it puts me at medium.

You might be medium light at the center. Maybe low light at the edges. It is a wide tank.

What different light would you recommend.

So I could hit low with two raised up right?

You could hit low with one, sitting on the tank.

Do you want low? I would consider two for the mere fact that a 40b has a good bit of depth to it. The lighting would not be very even with just one fixture. I guess it just depends on what you want.

I have 2 T-5NO dual bulb fixtures on my 40Bs. Like stated above, using just one darkens either the front or back.
