I saw them today for only $35, and I am considering using them as lighting over my low light 55 gallon tank. They would fit into the hood perfectly. I found correct spectrum and length bulbs for sale online, but am confused about one thing. My friend mentioned that there is a difference between t5's and HO t5's. If the fixture at home depot is not high output, could I still use high output bulbs in it? And if so, what would be the drawbacks?
Thanks.
Thanks.
