Arcadia Marine White T5 54W 1150mm (46") Lamp

Arcadia Marine White T5 54W 1150mm (46") Lamp

The colour temperature and spectrum of the Marine White 14,000K Lamp, coupled with its high lumen output (particularly for the T5 lamps) replicates the intensity of the sun around shallow coral reefs.
• High Output T5
• Powerful penetrating white light
• Accentuates natural fish colours
• Colour replicates reef environment

The Arcadia Marine White lamp has a colour temperature of 14,000K (Kelvin) and an exceptional lumen output combined with very good colour rendition. The tri-phosphor formulation provides consistent long life and stability of output at these high levels of performance.



These factors make it the ideal choice for the serious marine aquarist, with excellent levels of light throughout the aquarium and extraordinary clarity for viewing the constantly changing marine environment.



A high proportion of light energy is concentrated in the area between 400 and 480nm, which also assists in the promotion of zooxanthellae production to encourage coral and invertebrate growth.



The other peaks across the spectrum allow the true, vibrant and natural colours of the fish, corals and invertebrates to be enhanced and to really stand out.

T5 lighting - Increased power from fluorescent tubes

Increased Power
Increased Intensity
Increased Penetration
T5 - A short phrase, which has sparked much debate recently, but what are the facts?

What does T5 actually mean?
The 5 is obviously relevant, and being as so much has been spoken about how much better these are than average fluorescent tubes, then surely it must refer to an aspect of the light which is five times greater - probably the strength of its output, or maybe its effective distance, or expected lifespan.

This is the understandable, but incorrect conclusion that many people draw. What the 5 actually refers to is an aspect of the tube that your fish, or invertebrate livestock, could not care less about - its diameter.

Technically, any fluorescent tube should be referred to by the letter T followed by a number. That 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.

So why all the fuss?
Small 12" long, 8Watt tubes have been on the market for a long time - these are only 5/8 of an inch diameter, but they don't appear to be any more powerful than a regular tube. The reason being that these are regular output T5 lamps - when talking about the new type of lamps, we should strictly speaking refer to them as high output T5's, and it is the high output part that really makes the difference - producing a light of much greater strength than a conventional tube, and as a result the energy input into the aquarium is greater.

Also, light diminishes very rapidly as it travels through water, but with T5 lamps the effective distance is significantly greater than with conventional tubes, meaning that deeper aquariums can be maintained with an illumination that is effective to the base.
