Zoo Med Coral Flora Sun Plant Growth Bulb T8 17 Watts, 24-Inch

Unlike the more effective light bulbs sold for the more expensive light fixtures intended to promote lush growth for most types of aquatic plants, these bulbs are intended for use in the less expensive fluorescent lighting fixtures, the kinds that come with most aquarium kits. These are the standard black light fixtures that sit on the glass top and that require light bulbs that are 6" shorter than the actual length of the fixture on the outside. So, this 24" bulb fits a 30" light fixture (which in turn is intended for 20 gallon long; 29 gallon; 37 gallon tanks), and these T8 lights, although thinner than standard fluorescent tubes, have pins that fit in standard fluorescent fixtures.

Among the less expensive light systems, this Zoo Med T8 bulb is great. The tube is much more effective than the standard fluorescent tube. This is especially true as long as you select the correct plants (Java Moss, Anubias, Hornwort, Anacharis etc.) for less light (especially if you have a deeper tank). My plants chosen for low lighting are doing well with these bulbs, but when I tried to grow plants with greater light requirements under these Zoo Med tubes I found I had to transfer the plants back to their original, better lit tanks as they were not doing as well as before.

Not good for aquarium. I tried this for my planted 30 gallon tank, but it gave off poor color, dull looking fish and plants. Much happier to spend a few extra dollars on another brand.

This was a really good price, and was nice that it fit into the stock light on my tank. However, my plants really didn't like this light. They all died, and I am incredibly disappointed. I'm just going to use the regular florescent bulbs for now. Which made the tank look nicer in my opinion. This Zoo Med bulb brought out the red in the tank, which I didn't like. I prefer the cool colors, and the regular flourescent had more of a blue light effect as opposed to the red.
