    Actinic white lamp that enhances blue and violet marine colours.

    • 60% Marine White 14,000K / 40% Marine Blue 420nm
    • Actinic white lamp that enhances blue and violet marine colours
    • High photosynthetic light content


    The Marine Hybrid is a new T5 lamp formulation based on a 60/40 phosphor mix of our Marine White 14K and Marine Blue 420nm lamps. The resultant spectrum of the lamp combines high brightness, with large amounts of energy in the photosynthetic wavelengths required for coral growth.

    With a strong actinic peak to fluoresce corals, the Marine Hybrid lamp emphasises blue and violet colours in the aquarium, without flattening reds and greens, giving a natural reef appearance.

    For smaller aquariums the Hybrid lamp works well on its own or combined with the Marine white lamp, while in larger T5 lamp arrays, a mix of Arcadia Marine Blue, Marine Hybrid and Marine White lamps will produce excellent results.

    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.
