The Hydra TwentySix HD used 80-degree focusing lenses for a good balance of light spread and focusing power.

The Hydra draws 90 watts at full power. The aluminum fixture housing acts as an efficient heat sink so the aquarium water stays cool.

My Pick

For a freshwater fish tank that does not need sophisticated dimming, color customization or a remote control, consider the Nicrew LED aquarium light. The economical price and simple operation make it an attractive replacement for an old fluorescent-style aquarium light or when setting up a new aquarium. Unlike the Marineland LED, which can easily get knocked into the aquarium water, the Nicrew LED fixture gets “locked” onto the top of the aquarium frame, providing a secure light mount. Since the Nicrew does not come with a timer, consider the Zoomed AquaSun Aquarium Timer. The timer is easy to set up and can even be bypassed if necessary. A red LED indicates when the outlet is turned on.

If you’re raising live aquatic plants or maintaining a reef aquarium, you’ll probably want a few more options when it comes to light color and timer control. The Aquatic Life LED Aquarium Light Fixture, whether in freshwater or marine style, will give you features entry level LED aquarium fixtures don’t have. The variety of different colored LEDS and three channels of automation provides more control for the advanced freshwater aquarist or reef-keeping enthusiast. The slim design and on-tank mounting system fit into any decor. The Aquatic Life LED fixture is a blend of simple operation with a nice set of programming options for freshwater and marine aquarists.

For a high-tech planted aquarium containing sensitive Amazonian plants, consider the Kessil A160WE Controllable LED Aquarium Light. The controllable light spectrum and intensity works hand-in-hand with carbon dioxide injection, providing optimal conditions for aquatic plants. The 6,700K lighting is ideal for stimulating freshwater photosynthesis. The shimmer effect makes the aquarium look like a tropical stream, enhancing colorful fish and aquascaping.

Reef enthusiasts know good lighting is necessary for the reef to look good and remain healthy. Every reef aquarium is different and requires customized lighting in order to maximize coral growth and vitality. The Euphotica LED Aquarium Light Fixture for Saltwater/Coral Tanks will give you the ability to control all aspects of your reef lighting system. The narrow-beam lenses focus all of the light energy straight down onto the reef. One of the most attractive and useful features is the ability to suspend the light fixture above the aquarium. You are able to adjust the light height as needed. It also gives you the option to add as many light fixtures as necessary. This modular design makes the Euphotica fixtures very adaptable to larger reef aquariums. The fact that a single remote control can manage multiple lights makes controlling multiple fixtures a seamless operation. The light fixtures can also be managed by the touchpad feature mounted on the front of the light.

No one likes to push the limits of technology more than reef-keepers. The investment in live corals, rock and fish is substantial. For deep, wide or long reef tanks, take a look at the AquaIllumination Hydra TwentySix HD or the larger Hydra FiftyTwo HD LED aquarium fixture. The rugged construction and name-brand LED circuits make the Hydra series a reliable and powerful lighting option. The Hyda LED aquarium light fixtures will provide the proper light spectrum and intensity needed by reef-building corals. The myAI app allows you to control the lights with smart devices or computer from anywhere in the world. The app even syncs the Hydra light with the earth’s lunar cycle. The myAI app will also allow you to view your aquarium with a Nest camera!
