39W - 850mm / 34” (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.

Customer Reviews

Excellent customer service – Review by Mattk (Posted on 04/12/2018)
I recently ordered a tank bulb from iquatics i received a phone call from a nice young lady who informed me they had a buy 2 get 1 free offer but then it turned out i had ordered the wrong bulb she took the time to help me find the right one then it was delivered next day.
My tank now looks amazing with the right lighting i will definitely be ordering again.
They have the best customer service.

Great service and items – Review by Min (Posted on 21/03/2017)
I purchase 3 lights of which one as a different size. I quickly had an email querying if the order was correct as they didn't want to ship it out and me be disappointed when it arrived if it was wrong. I said it was correct (brought tank 2nd hand and eejit put different size bulbs in at either end!) So now have white purple and blue and fish look amazing. Thanks for such great customer service too can not be faulted!

Great Stuff! – Review by Jacques (Posted on 23/09/2014)
I have a four foot marine tank that is well established and thriving. Soft corals and fish/invertebrates. The product quality seems great, it was well packaged and frankly the service was brilliant. I was after some advice on my lighting and the team were really helpful, exchanging several mails with friendly advice on what I might want to try. I bought 6 t5 tubes plus the reflectors and was very impressed with all of it. Great job iQuatics!
