There are many factors to consider when choosing a fluorescent lamp for your aquarium.

Firstly what type of aquarium system you are running?

Freshwater habitat system (i.e. rivers and streams)
Either for “cold” or “hot” water fish, invertebrates, (freshwater crab/shrimp) and/or plants. Goldfish are a good example of “cold” (or temperate) water fish while guppies are an example of “hot” (or tropical) water fish.

  1. Original Tropical
  2. Freshwater
  3. Plant Pro

Marine habitat systems (i.e. the sea)
Saltwater environments with “Nemo” and “Doreen” type fish in. Sometimes they may also include invertebrates (saltwater crabs/shrimps) and corals.

  1. Marine White
  2. Marine Blue
  3. Marine Hybrid

Fluorescent lamps are available in T8/T5 tube and compact formats.
We offer various different sizes in each format depending of the size of your aquarium and the output you require.

Are there any other differences?
There are several other benefits in T5 technology lamps compared to T8 technology, these are shown below:-
• The T5 is 40% smaller in size, so can physically fit in more in the same space.
• The T5 has a better light spectrum
• The T5 has a higher luminance (Surface brightness of the lamp)
• The T5 has reduced power consumption due to the improved luminance rating, as it operates at a higher temperature. (This can provide typical energy savings of 30%)*
• The T5 has a longer lifespan, up to 25% longer+
• Reduced mercury levels used in the lamps.

(* +) These benefits are gained in conjunction with the use of a quality Arcadia electronic ballast unit.

Original Tropical Lamp

Original Topical Lamp Lit

Designed specifically around the red and blue wavelengths in daylight that are necessary for photosynthesis.
This gives a warm pink light that encourages plant growth and highlights the iridescence of many tropical fish.

Freshwater Lamp

Freshwater Lamp Lit

Has the highest colour temperature of all our freshwater lamps at 6,900K and the most neutral colour rendering. The spectral output of the lamp has been tailored to closely resemble daylight, while enhancing the greens of aquatic plants.

Plant Pro Lamp

Plant Pro Lamp Lit

Specifically formulated to combine the red and blue spectral peaks of the Original Tropical lamp to support plant photosynthesis, with the higher light output of the freshwater lamp.
The result is a lamp which is noticeably brighter than the Original Tropical, making it ideal for more demanding plant species.

Marine White Lamp

Marine White Lamp Lit

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.

Marine Hybrid Lamp

Marine Hybrid Lamp Lit

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.

Marine Blue

Marine Blue Lamp Lit

Re-creates the effect of a moonlit ocean and with a spectral peak at 420nm will bring out a corals natural fluorescence.

Important – please read carefully

Before changing your lighting product to a new lighting product, always ensure that you plan plenty of time to acclimatise your corals to the new lighting source that you are changing to. This can be done by running the old lighting unit alongside the new lighting unit or by raising the new lighting unit higher than the old lighting unit position. This is to reduce the lighting stress that can be created to the corals of a much more powerful lighting source than the one they have become accustomed to. This could lead to the changing of their symbiotic Algae and Bacteria types and numbers present and if done too quickly may end up killing them off and bleaching the corals.

This needs to be taken into consideration for all technologies of lighting whether it be fluorescent, LED or metal halide lighting forms. Arcadia cannot be held responsible for any issues with corals or any other inhabitants due to improper acclimatisation of your corals /inhabitants to the new source of lighting you have provided for this purpose.
