Yes. I bought my 29g which came with an Aqueon hood and it had one of these tubes. They are very weak light, half the intensity of the tubes i mentioned previously. They also cast a purplish hue which I don't like, although that is aesthetic. The intensity is the issue. The hood and fixture I really like, the glass is well sealed.
If the light is rather purplish, this is certainly what you have. Measure the tube end to end, that is the tube length (not including the prongs), it is likely a 15" or 18" tube, so you look for that in one of hte tubes mentioned earlier. Finding these small tubes in hardware stores is not always easy, so you may have to go with the more expensive tubes from a fish store. Depends where you live, and the stores there. I know they are limited where I am.
