Which would you go with to light a large tank. Which is more efficient? Any advantage of using one over the other?
After doing some homework I found that those had horrible ratings. This is just what I found, of course you don't always hear about the ones that worked just fine. :roll:MrZ2u said:I believe so but they are about the same price as a plain bulb so it is not really a big issue. Since the actual spectral output is of no concern they should last several years before the bulb or ballast give out.
T5's will amaze you...I have seen reefs run on just them alone and they are fantastic. Really PC lights have almost gone out of favor as solo lights in the marine community. About the only place they are still found are the nano reefs where their small size if needed and on some metal halide fixtures to provide the actinic light. Dollar for dollar they are hard to beat.
