iQuatics 54W T5 White Marine 14000K

54W - 1150mm / 46” (length) – 5/8”- 16 mm (diameter)

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.

Why T5's

Key Benefits of our High Output T5's:

  • Greater Intensity
  • Deeper Penetration
  • High Power

Our Marine White 14000K High output T5 replicates the light intensity found at shallow depths. The light wavelengths are within the ideal range for photosynthesis and coral growth.

With its blend of mixed daylight phosphors, it enhances your coral’s colours making the reds, blues and greens more vibrant. With slightly more blue content than a standard 10000k white tube, the 14000k will give you slightly deeper penetration.  To help balance out the slight yellow hue, these are ideal to use alongside our Blue range whether it be our Blue Plus, Aqua Blue 50:50 or Marine Blue Actinic, to increase the blue light content for perfect coral growth.

This is the more common choice for marine keepers.

24W – 550mm/22” (length) – 5/8”- 16 mm (diameter)
39W - 850mm / 34” (length) – 5/8”- 16 mm (diameter)
54W - 1150mm / 46” (length) – 5/8”- 16 mm (diameter)
80W - 1450mm / 58” (length) – 5/8”- 16 mm (diameter)

EXCELLENT – Review by Bell (Posted on 15/06/2016)
These lights are much better than the ones I had previously. Your advice about what combination of lights to purchase was helpful, ( white, purple, special aqua blue) , delivery was very fast, well packaged etc. And all of this much cheaper than the equivalents in my local aquatics shop which don't stock your T5s, but all the staff in there use them! Will buy again.

Posted by Keith on Tuesday, 27 September 2011


Does your buy 2 get one free offer on bulbs only work with the same bulbs? eg if I buy 1 blue + and one 14k can I get another bulb free or do I have to buy 2 of the same bulbs for the third?


  • Posted by Richard Latham on Tuesday, 27 September 2011
    You can mix and match the t5 tubes and still take advantage of the Buy 2 get 1 free offer. The cheapest tube will be the free one.
Posted by Michael on Tuesday, 27 September 2011


Do you sell these tubes in 10000k?


  • Posted by Richard Latham on Tuesday, 27 September 2011
    We have stopped manufacturing the 10000k t5 tubes due to the popular demand of the 14000k, any we have in stock will show up on the website.
