Aquariums come in all shapes and sizes these days and thankfully so do the lighting sources. Long gone are that days of trying to hang a fluorescent tube on the back of a tank dangerously close to the water and electrics.
Now, we have a wide variety of LED lights to choose from which are safer and cheaper to run. Less wattage but more light output and a better spectrum of light means they are perfect for growing plants and corals.
So which LED Aquarium light should you buy?
Quick Links below:
The best 7 Aquarium LED lights are :
- KZKR LED Light

Do you want to enhance your freshwater or saltwater marine aquarium with a purely natural glow? If yes, then add in the Full Spectrum LED Aquarium Light which comes in a diverse array of eleven sizes. To begin with, this light is equipped with three optional control modes that include Only Blue LED ON, ALL LED ON and Close. Moreover, the best part is that if one LED exhibits dysfunctional properties, the problem does not diffuse, or hinder the functioning of the remaining LEDs.
Furthermore, to mimic daylight and moonlight, the LEDs provide 16*Red, 8*Green, 62*Blue and 121*White.
This Aquarium light also includes two extendable brackets, a power supply, and a useful user manual to guide aquarists of all backgrounds.
- With this upgraded version, you gain access to five bright colored full spectrum LEDs (5730SMD) that allows for lustrous plant growth, increased aesthetic visuals and casts a brilliant burst of color on every aquatic plant placed inside the aquarium. (Customization of light functions)

It accurately emulates the elements of a natural marine ecosystem by incorporating traits of sunrises and sunsets. Furthermore, this environmental mimicry creates a synergetic condition whereby the photosynthesizing plants produce oxygen-rich aquariums. In addition to that, each light serves its own well-being promoting function; purple (430nm) promotes fish growth and sterilization, blue promotes coral health with increased Vitamin D3 uptake along with calcium and red (660nm) may lead to healthy fish growth. SPS and LPS thrive in this easily controllable light.
To keep the equilibrium at bay, there is a balance between both, PAR/Lumen Output and Coverage.

Types of Lighting
Aquatic life quality has a symbiotic link to the quality of light, intensity and the spectrum of colors that it receives. Let’s look at what type of lighting you’ll need for your aquarium to provide the best lighting possible for your fish, plants, corals and invertebrates.
- Light Emitting Diode:
LEDs emit light as exited subatomic particles pass through a semiconductor material i.e. electroluminescence. This requires relatively lower energy, producing a bright light that is both efficient and delivers on brightness for up to 50,000 hours. A diverse range of uses includes supplemental lighting or major lighting for aquatic tanks. (0.05-5W)
However, without proper ventilation, it may become prone to damage via heat.
- LEDs operate at extremely low running costs because the bulbs run at a minimal wattage. The perk is that this does not inhibit or reduce the illumination whatsoever. They take 80% less energy to operate. Energy cost savings in the long term are substantially large.
- LED units also run at a very low heat margin. They possess the attributes of inbuilt heat sinks and fans that are great thermal regulators and excellent at dispersing heat. Inadvertently, this lowers the rate of evaporation in an aquarium tank as well.
- LEDs possess an impeccably high-water depth penetration rate.
- Unlike other lights, there are no chances of UV Radiation production.
- As nature requires mobile setups, LEDs possess dimming traits that can be modified to suit the needs of marine life as desired. They can be programmed to imitate sunrise and sunset and integrates features of lunar cycles that can regulate your marine occupants.
- Compared to traditional lighting LEDs last up to 6 years.
- Standard Fluorescent:
Presents a diverse array of color options and sizes. They are relatively cheap and efficient and remain at cool temperatures. The bulbs last up to 6-18 months whilst generating 15-40W power. Furthermore, they can be placed within a fresh or saltwater community aquarium. However, they are not suitable for photosynthesizing plants or invertebrates.
- Compact Fluorescent:
These function at 10-130W of power and last up to 4-18 months. Despite needing more chilling options due to the high heat production these possess a longer lifetime survival rate than standard fluorescent lighting. There are also numerous sizes from which to choose. They can be placed in freshwater where the reefs are less than 24 inches deep.
- T-5 HO Fluorescent:
Perfect for reefs in freshwater less than 24 inches deep, these last up to 16-24 months granting them the status of high longevity. Provide high-intensity power of 24-54W whilst also being cool running.
- VHO Fluorescent:
Compared to most, these require a higher chilling assistant due to being prone to heating up. At 10-130W these last up to 4-18 months in freshwater planted reefs less than 24 inches. These last longer than your run-of-the-mill fluorescent lights and once more you have a vast supply of choices to pick from.
Your typical beginners’ start-up kit should include the incandescent lighting system. It’s predominantly used for small fish only as it fires off only 7-25W of power. This multi-colored inexpensive product will last you 2-4 months. The limitations, however, are numerous in that it heats up a lot, provides lower light intensity and has a narrow spectrum to offer.
- Metal Halide:
In tanks filled with photosynthetic corals and invertebrates and reefs of freshwater aquariums that surpass 24 inches, feel free to place metal halides. These function at 70-1000W of high power and last up to 6-18 months. Moreover, they provide the highest intensity, complemented with wide spectrum range availability. However, the only downside is the possibility of UV Radiation production and high heat.
Choosing the right LED aquarium light for your tank will involve a number of factors and not least the cost. It’s true to say over the last couple of years LED aquarium lighting has come down in price. Now you can think about other contributing factors and not just the price.
