that coralife t5no fixture is sketchy at best, even if it was the right light for your needs. I have personally burned through over a half dozen of the 30 inch versions myself all in just a few months. Bulbs flicker and burn out like crazy. I figured picking up a couple of $30 lights for my tank would save me money, but at replacement bulbs costing about $15 a pop I quickly ended up spending more than I would have buying a more quality fixture in the first place. Because of my experience with that light I will not be buying more coralife products, and have made the switch to led so I (hopefully!) wont have to replace bulbs for a verrrrrry long time.
