The aquarium light is a strange concept for those who start to learn about aquarium fish farming. As its name suggests, the aquarium light is an electronic device used to provide light for the aquarium. The fishes and other aquatic species living in the aquarium without the aquarium light may get an illness or even die. Besides, the light is also utilized to decorate the aquarium more sparkling and brilliant.

In the current market, there are numerous aquarium lights including compact fluorescent bulbs, standard fluorescent bulbs, metal halide lights, LED aquarium lights…, in which the LED aquarium light is the newest type. 

LED (Light Emitting Diode) aquarium light contains several LED chips which can emit high-intensity light for the aquarium with low power input and without giving off heat. Thanks to its strength of low power consumption and high efficiency, LED aquarium light is the most popular aquarium light. 

What makes LED Aquarium Lights different from other aquarium lights? 

To explain the reason why LED aquarium lights can alter other traditional options on the world market, we will list 6 differences of the LED aquarium lights from other aquarium lights. If you are confused about whether purchasing LED aquarium lights or choose other options, this part is the key information for you to make the right decision. 

 Differences between LED and other aquarium lights
Differences between LED and other aquarium lights

#1. Long-lasting 

The strongest advantage of a LED aquarium light compared to other traditional aquarium lights such as fluorescent light or incandescent light is its longevity. The average lifespan of a LED aquarium light is approximately 50,000 hours of operation (equivalent to 6-7 years), while the longevity of traditional incandescent bulb, standard fluorescent bulbs, the compact fluorescent bulb is only 2-4 months, 6-18 months, 28 months, respectively. In the long term, LED aquarium light is the most economical option for the fish tank. The long lifespan of LED aquarium light also helps the aquarist save the time and effort to change the permanent new bulb.

#2. Energy efficiency

It is proven that a LED aquarium light takes less energy to operate than other types of aquarium light (including traditional incandescent bulb, standard fluorescent bulb, and compact fluorescent bulb). With the current high technology of LED, a LED aquarium light uses 80% less power than the others. 

Although the price of LED aquarium light is higher than other options, the total cost including fixed initial cost and operation cost will be lower than incandescent bulb and fluorescent bulbs after 12-18 months thanks to its longevity and energy efficiency

#3. Adjustable light intensity

The suitable light intensity for each aquarium is different since it depends on various factors such as the type and the number of aquarium plants, the type and the number of fish, the other light source in the room, the algae appearing in the aquarium… Therefore, it is convenient for the aquarist to use LED aquarium light to raise the new fish, replace the old aquarium plants with the new one, or change the location placing the fish tank because they can adjust the light intensity easily and do not have to buy the new one.  

Some new high-technology LED aquarium light is programmed to automatically adjust their light intensity. The light intensity decreases at sunset and goes up at sunrise. The feature is excellent for the fish to calm down and relax at night. The blue light is regularly employed to simulate moonlight at night.

The newest technology currently is smart LED aquarium light. The aquarists can change the light intensity remotely by smartphone. 

#4. Cool Running

Different from the incandescent bulb producing light by generating heat, the LED aquarium light illuminates the spectrum through the principle of electroluminescence. So, the LED aquarium light only generates little heat. Thanks to this, the fish, aquarium plants, and other species are not affected by the sudden change in temperature when turning on/off the light.

#5. Multiple Colors

The majority of LED aquarium light currently has multiple colors. The most common combinations are: white – blue, white – red – blue, and white – red – green – blue

  • White color: is used to simulate the sunlight
  • Blue color: is used to simulate the moonlight 
  • Red-green-blue color: is beneficial to the growth of aquarium plants

4 Things to consider when buying LED aquarium lights

#1. Size of the fish tank 

Definitely, the first thing to be considered must be the size of the fish tank. Based on the volume of the fish tanks, the aquarists can calculate the suitable power rate for their tanks. As experts advised, the aquariums require from 55 to 225 lumens per gallon depending on the density of species. This means each gallon of fish tank needs between 1 and 4 Watts from LED aquarium light. 

Besides the volume of the fish tank, the depth is also a vital indicator. A good LED aquarium light must emit the spectrum from the top to the bottom of the fish tank in order to ensure that all fish and other species can receive similar lighting.

The tank with less than 22-inch depth needs a power rate of about 175 Watts LED aquarium light, the 18-22-inch one requires approximately 250 Watts. For the deeper fish tank, the aquarist must use a much higher power input LED aquarium light (maybe 400 Watts or more). 

#2. Type of aquarium plants

The fish tank is normally decorated by coral or other aquarium plants such as moneywort, hornwort, rotala rotundifolia, pygmy chain sword, hygrophilia polysperma, cryptocoryne wendttii… Each type of plant in each growing phase needs distinctive light intensity. 

Some plants grow better under low light such as: hygrophila, java moss, java fern, anubias, vallisneria, rotala, sagittaria… These plants are only required from 35 to 80 lumens per gallon, equivalent to between 1 to 2 Watts per gallon. 

The medium-light aquarium plants include: cryptocoryne parva, dwarf sagittaria, bacopa monnieri… These plants are suitable to plant under the shade of other high plants. It is suggested to put them from 80 to 160 lumens (2-4 Watts) per gallon.

The aquarium plants required high light consisting of elatine hydropiper, Eriocaulon cinereum, fissidens fontanus, glossostigma elatinoides, glossostigma elatinoides… These plants need at least 160 lumens per gallon, corresponding to more than 4 Watts per gallon.

  • Red light (630-700 nanometers): 50%
  • Greenlight (500-580 nanometers): 35%
  • Blue light (435-495 nanometers): 15%

In addition, the moonlight blue light is soft and good for fish to relax and calm down at night. 

#4. Cost vs Your Budget

It is advised that the aquarists should develop a budget for their aquarium including aquarium LED light. Because there are many types of aquarium LED lights with various prices on the market. Some aquarium LED lights cost a high price with unnecessary characteristics for your fish tank. So, the aquarists must read carefully the specifications to find out their perfect LED aquarium light.
