The best LED aquarium saltwater lights

LED Lighting Overview

LED Lighting has become very popular in the marine aquarium. The best LED lights for growing coral have higher wattage and improved functionality over cheaper LED fixtures. LED technology improved significantly over the last decade, 2017 has some great LED options for the coral hobbyist.

Gone are the days of hot and expensive Halide lighting that required frequent bulb changes. Spectrum and intensity are often adjusted via a remote control. LED’s have won the marine coral lighting war for three main reasons:

  1. Previous Metal Halide lighting resulted in a huge amount of heat when left on for long periods. Chillers were often needed as the water temperature could spike when the light was on. LEDs on the other hand run very cool for hours at a time.
  2. LED lighting has become very affordable over the last 5-10 years. They are low cost and can deliver extremely high outputs.
  3. Most LED lights will last in excess of 40,000 hours without needing replacement. This equates to tens of years of aquarium use. LEDs are also low wattage and consume little energy for powerful output.

2016 has some excellent, affordable and coral ready lights for the marine aquarium. In fact there are many MANY units available on offer. This review covers the most popular fixtures available – the best led lights for growing coral. Prices range from sub $100 to $500+.

Current USA Orbit Marine Aquarium LED Light

Orbit marine LED, one of the best saltwater LED lighting units

The USA Orbit Marine Aquarium LED Light is one of the most popular saltwater aquarium lights. It is also one of the best LED lights for growing coral for the beginner coral aquarium. The light comes in standard sizes and will fit most marine aquariums. It has a controller and computer that enables light ramping, moonlights and more. The light also has the ability for colour adjustment so you can choose a temperature that best suits your tastes. It is best lights in terms of cost for low tech or FOWLR setups.

However, if you are looking for a super high intensity light, to grow SPS hard corals for example, the USA Orbit is not the best choice. Users report positive results growing SPS in very shallow tanks (less than 12″) but deeper aquariums are not recommended. This light is recommended for enthusiasts that want to grow softer corals at shallow depths (Between 0 and 2 ft). Any deeper and you will need to purchase a light with higher intensity and shallower focus.

Awesome because:

  • The light is very low cost. Especially for a marine light capable of growing beginner corals. At the time of writing the light ranged between $110 and $180 dependent on size.
  • Come with a controller and a range of adjustable settings
  • Is available in many stock lengths for different tanks
  • Multiple units to increase wattage per gallon or improve overall brightness
  • Reportedly very good customer service from the brand.

Not so awesome because:

  • May need multiple units for keeping more serious corals
  • Not the best light for keeping hard corals or SPS.
  • The only real downside is power. If you need super high wattage this light is not for you.

AquaIllumination Hydra TwentySix +HD LED Light

Hydra Illumination series, one of the best saltwater LED's on the market.

Its a great light for the marine aquarium. The light has accurate color representation and can output any color at 90W. Growing coral is possible down to a depth of 24″. The big sell of this light is not requiring an external controller to run single or multiple units. It is wifi capable and will respond to commands via your smartphone.

Awesome because:

  • Looks stunning on the aquarium, especially when mounted from the ceiling or braces from behind the tank. Ergonomics are a big part of this light.

Its an excellent light for those starting out in the hobby as it allows keeping of corals without breaking the bank. The light intensity can be increased as confidence and experience grows.

Kessil A360WE Controllable LED Aquarium Light

Kessil Saltwater LED, a beautiful coral growing light that is one of the best choices on the market.

The Kessil A360WE Controllable LED Aquarium Light is an excellent choice for the marine aquarium enthusiast. This light is small and ergonomic. Its hard to understand how such a small unit can output very high intensity. Kessil A360WE have great coverage (24 x 24″) which means most users can get away with just two units over a 4′ + setup. They shine from a single point and have noticable shimmer. The shimmer is similar to the sun shining into the ocean and is a very nice effect.

The Kessils are renowned for great color and the A360WE is no exception. The A360WE is one of the best LED lights for growing coral for users who want a sleek, refined and simple setup. The Kessil is powerful and well priced against competitors.

  • 24″x 24″ coverage is impressive for a light of this size. Only a few units are required for much longer tanks whilst still being able to grow corals.
  • 90W of power is more than enough for most users. Their optimisation of intensity (up 15% from the previous models) makes this light more efficient than cheaper models with more LEDs.
  •  Shimmer that is similar to sunlight on a real life reef..

Not so awesome because:

  • Expensive light for a small unit. The light can exceed $400 per unit which can be costly for larger aquariums.
  • Coverage is generally in a square shape. It’s not as effective for thin or narrow aquariums.
  • Less customisation of other units when changing color.
