Wal mart plant/aquarium lights
 
I have them on a 55 gallon tank and I'm curious if they are considered high lights or low lights?

We need to know what fixture it was, how many bulbs there are, and/or the wattage on the bulb.
Without any of those variables, we don't know

Gotcha. 2 and I think they're 25 watts and they are tubes

So you have two, T8 bulbs, each 25W.

I would say you have low light.

Agreed, definitely low light.

That's what I thought. Someone on here said high light but I was thinking no.

Tubes that screw in or have metal prongs at each end? I don't know of any fluorescent bulbs that are 25 watts but regular incandescent bulbs can be 25 watts.

If the bulbs screw in and look like regular light bulbs then they are useless for plant growth. If you had a lot of them it would work, two - not a chance.

However you can go back to the store and buy fluorescent screw in bulbs that will support plant growth. I don't know how many you need over a 55 gallon tank but this type of bulb works very nicely in pairs for 10 gallon tanks.

Can you post all the writing on the bulb, and look on the package for more info?

I do not see how anything purchased at Wal Mart is going to be good for a planted tank, and I agree with the above, highly likely low light or very low light. Not going to grow plants unless the tank is next to a window, then it is the window, not the light fixture.

I have several tanks that are 4' long (I am assuming your 55 is a standard tank) but none of mine are as tall as a standard 55 gallon. Mine are 16-18" tall. 45 gallons.
I run 2 bulbs, T-8, 32 watts each over these tanks. Each bulb is 4' long, and there are DIY reflectors over the bulbs. That is low light. If we were still going by watts per gallon I have 64 watts over 45 gallons. Just about 1.5 wpg. Now add in the light that comes through the window.

Over my 72 gallon tank, 2' tall I have 4 of the same bulbs: 4 x 32 watts over 72 gallons. That one also is low light.
