Arcadia T5 Marine Hybrid is a 60% Marine White and 40% Marine Blue lamp for reef and marine aquariums. The resulting 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 Arcadia Marine Hybrid lamp emphasises blue and violet colours in the aquarium, without flattening reds and greens, giving a natural reef appearance.
