Ohh you are asking about the tubes in the fixture and not the fixture itself. LoL I see now. I would just go to Lowes or Home Depot and get two daylight bulbs that size.
I have 2 GE daylight bulbs from lowes in my fixture. They are 6500k a piece.
Or the two bulbs Byron suggested.
I am not sure about the you are asking about and probably wouldnt waste my money on it.

Yeah those work great and the best part they are cheap. LoL. For a little more money the ones Byron mentioned will be a little brighter intensity wise.

The GE bulbs at the link are 3100K color temp, which seems too warm (color wise) for optimal plant growth. Would need to see the spectral graph to be sure, but a bulb with that low of a Kelvin rating will likely not produce enough blue light for plants. While Kelvin rating and spectral output are not the same thing, they are somewhat related and we can infer the spectral output from the K rating. A 6500K bulb reproduces midday sun, which will almost have to include blues and reds (good for the plants) along with other wavelengths (to produce a whiter/cleaner light) - they will probably be cheaper as well.

Quantum found the data. I usually avoid any so-called plant or aquarium tube as the spectrum is almost always blue and red which turns the tank purplish, and these tubes are always less intense light than full spectrum or daylight.

Amanda, if you keep the same fixtures, the tubes i suggested earlier might give a bit more intensity, but it will be marginal over the cheaper. Daylight with a 6500K rating is your best bet.
