To give you the best color rendition (CRI rating) and bring out the naturalīeauty of aquarium fish and plants in both freshwater and marine tanks,Ĭhoose a daylight lamp with a full spectrum of visible light.Ī CRI as close to 100 (the CRI of natural sunlight) is desirableįor visual affect. Of the visible spectrum in proportion to that of natural sunlight. Full Spectrum Light/CRI Ratingįull spectrum light is a light source that emits all of the wavelengths Latitudes and at different water depths in their natural environments. This wavelength is very dangerous to all animals.ĭifferent spectrums are required for different UVC is the wavelength used for Ultraviolet Sterilizers which kill Violet (UVB) is needed for many animals to assimilate calcium This is a criticalĬomponent for reptiles in that the 320nm range of Is the spectrum which gives humans a suntan. UVB is the non-visible wavelength of lighting. Invertebrates and also helps stimulate feeding and breeding behavior The 420nm blue (UVA) range is particularly important to marine corals and Responsible for the "physiological well being" of fish. UVA is the visible wavelength of light and is The sun has 3 wavelengths: UVA, UVB, and UVC. Remember your red, orange, yellow, green, blue, indigo, violet light spectrum?īelow are two light bulb spectrums represented visually by peaks and valleys Light spectrum runs from violet on the short end (320 nanometers) The most obvious use of lights is to light the tank so that you can see A fish-only tank will benefit fromĬorrect lighting with increased coloration, activity and spawning. Under-water environment that is both healthy and visually appealing.Ĭorals and invertebrates use lighting to regulate and assist inĭigestion, feeding, reproduction and growth. High priority for tropical fish keepers if they wish to simulate a true Lighting is of VITAL importance to the marine aquarist and a The average aquarium set-up contains oneĪll-purpose bulb which implies that special lighting is not necessary. Most novice aquarists underestimate the importance of lighting
