High Output T5’s are better to use in your aquarium lighting than the regular T8 as they have increased water penetration and are more efficient. You don’t lose the illumination at the bottom of the deeper tanks. With this lighting you are not restricted as much to the content of your aquarium, stock levels can be increased without the worry of inadequate levels of light.

The greater intensity, deeper penetration and Higher output allows you to stock your tank with a wide range of soft corals and allow them to flourish which was not possible with T8 Fluorescents.

Key Benefits of our High Output T5's:

  • Greater Intensity
  • Deeper Penetration
  • High Power

Ballast Dimensions:

  • 270mm(l) x 26mm (h x 32mm (w)
