    The Marine Blue 420nm Actinic lamp re-creates the effect of a moonlit ocean and brings out corals natural fluorescence. Unlike many competing products the Marine Blue Lamp peaks at 420nm, the optimum point in the spectrum for marine fluorescence.

    • Spectral peak at 420nm to fluoresce corals
    • Promotes marine photosynthesis
    • Moonlight effect ideal for night-time viewing

    The Arcadia Marine Blue Actinic lamp range has been created to provide the specific spectrum (400 – 480nm) necessary to achieve the blue chlorophyll absorption for zooxanthellae symbiosis to develop. This concentration of light energy in the so called ‘actinic’ range peaking at 420nm, is essential for the survival and good health of fish, corals and invertebrates in marine aquariums.

    Another important element of the Arcadia Marine Blue Actinic lamp is the UV output present, which creates a very pleasant fluorescent effect on corals, invertebrates and exotic marine fish. When used at night with no other lamps, the effect is of a dark moonlit night with the vivid colours of the corals and invertebrates fluorescing brilliantly.

    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.
