to add chillers to keep aquarium water cool

One major benefit of LED lighting revolves around the energy efficiency of the units. A typical LED fixture that has 100W of LEDs is an incredibly bright light. In fact, it can penetrate down to the bottom of deep aquariums and scorch corals that have not been adjusted to their intensity. Watt per Watt, LEDs provide more light output than either T5 fluorescents or metal halides, which adds up to significant savings in electricity to both power the lights and to cool the tanks.

Currently, most aquarium kits that include a light or hood with a light, do not offer LED lights. Popular combination units, such as the Eclipse systems are only offered with standard fluorescent light bulbs. Likewise, most light fixtures are still offered primarily with fluorescent lights. The LED fixtures that do exist tend to be a bit more costly to purchase up front, but you'll more than make up for it over time in energy savings as well as bulb replacement costs.

36-48 Inch Current USA Orbit Marine IC LED Aquarium Light with Controller, Good (2 Units), $217.57 LED lighting has been with us for many years, originally in the aquarium hobby, LED lights were added to the aquariums to produce lunar lighting as they cast a blue glow over the tank once the main lighting had switched off for the day, these small units use small lights in strips, often only containing 12 – 24 small bulbs for illumination. Ornaments for the aquarium can also be illuminated by small LED units but what was required was a LED unit that was as powerful as Metal Halides and cost a fraction of the price to run.

For a TROPICAL aquarium (fish and plants): Use 1 x AquaBeam600 Light Strip per 2 sq. ft. of surface area.
Again, use the 8ft2 aquarium – you will need 8ft2 divided by 1lamp/2ft2 = 4 units.

It is not the light unit but the transformer



Saltwater reef tanks with corals, clams and other light needing organisms will need the high output, very high output Fluorescent or metal halide lamps. Certain corals, anemones and clams require very intense lighting levels that can only be provided with T5-HO, VHO and metal halide light sources. A general rule of thumb for reef tanks is between 4 and 10 watts per aquarium gallon. Many reefers have lighting systems incorporating metal halides and VHO Fluorescent tubes. Research the species you want to keep because light requirements can vary. Because of the amount of heat these light units can produce, you may need to get an aquarium chiller to keep your tank water temperature in an acceptable range. The expense of lighting a reef tank may be just as high or higher than the cost of the live rock or even the price of all the other equipment combined.Whats more is LED lights generate very little heat. LED lighting units for planted aquariums practically sell themselves. So we know the upsides. What are the disadvantages? LED has generally been less affordable than other lighting types. This has changed somewhat over the last 5 years. LED units are now equal cost or sometimes cheaper than the older technologies available. LED units can also be confusing to purchase and highly quality dependent. If one of your LED’s burns out it’s not easy to ‘change the lightbulb’. LED units are often hardwired and require a certified electrician to perform maintenance. That being said, high quality LED units should never need LED’s to be replaced.
