lighting for a 200L tank
 
Hi there

Looking to upgrade to a new tank from my 60L and found a nice 200L (about 52 us gallons) in my LFS that I might buy.

It has 2 x 39w T5 lights, not sure what bulbs are included with it, think they were 2 different K ratings but those could be changed.

My question is what kind of light output would this give me for plants?

Tank dimensions are 100cm x 40cm x 50cm.

Just wondering if it is worth buying this tank or find one with just the glass and buy a light unit for it.

Thanks
Josh

Ok well going by the watts per gallon thing which I know isn't completely accurate, the lighting is no where near good enough.

I don't know if they are t5ho and how much of a difference that would make if they are?

Going to go to my lfs and ask if they are t5ho today.

If they are, this chart says I would have high intensity... tank height 20 inches, on top of the tank, 2x t5ho. If they're t5no however then only low light, and i'm looking for a bit more than that as my current tank is only low light.
