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.

  • Powerful penetrating white light
  • Accentuates natural fish colours
  • Colour replicates reef environment
  • Promotes marine photosynthesis
  • Ideal for lighting African Lake tanks

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.

Product Safety

Lamps can be fragile pieces of equipment. Please follow the following steps to ensure the safe fitting and use of fluorescent lamps.

At either end of a fluorescent lamp you will see two brass coloured connection pins. These are the electrodes that take energy from the controller to start and run the lamp. These are quite fragile by nature. It is imperative that both pins are safely located into the pin sockets inside the lamp holder before the lamp is pressed into place. Failure to line the pins up correctly will cause the pins to bend and snap and break through the lamp cap rendering the lamp unusable.
The Ultra-seal lamp ring must be unscrewed from the lamp holder and placed over the lamp prior to fitting and only re-seated onto the lamp holder when you are sure that the lamp pins are seated correctly. High Output T5 lamp leads must be fully unwound also or you may notice lamp flickering or beaks in illumination. You can also use a very small amount of a substance like Vaseline to lubricate the lamp ring and so stop it fusing to the lamp after long periods of heat. After cooling lamps can be wiped clean with a damp cloth once every two weeks or so to remove any dust build up from the lamp, this in turn will help to maintain the lamps full output. The all important reflector should also be wiped clean at the same time.

Lamp Reminder Service

Is your lamp still emitting the correct amount of UV!

The amount of light emitted from a lamp decreases with the age of the lamp, particularly in lamps which emit ultraviolet radiation, so it is important to remember to change you lamps at the end of their recommended service life.
