With these T5 fluorescent tubes you get Increased power, intensity and penetration.
The number indicates the diameter in
8ths of an inch, so the one inch diameter tubes that most of us are
familiar with are T8 (eight 8ths of an inch), and the fatter tubes that
used to be the standard, and that are still used by some are T12.
So T5 actually only means a light with a diameter of 5/8s of an inch. |

T5 lamps
There are two T5 lamps for use with marine aquaria, based on the existing T8 marine fluorescents - the "Marine White", and
"Marine Blue Actinic" lamps, but with all the benefits
described above. For
the marine reef aquarium, this means that the choice of invertebrates
that can be stocked successfully is increased. Certain species that
would at best struggle to survive under T8 lamps, can now flourish under
T5 lamps, meaning that a reef can be constructed using a range of soft
corals, anemones, large polyp stony corals, and Tridacna clams. They
also allow for a deeper reef aquarium to be successfully maintained, as
the light that they emit penetrates the water further, and can satisfy
the light requirements of animals kept further from the light source.
The
Marine Blue Actinic T5 lamp produces a spectrum which peaks at 420nm -
This is the ideal wavelength for enhancing the natural fluorescence that
is possessed by many aquarium species.
