Aquarium LED Fixtures
The best aquarium led lighting fixtures are modular with advanced control. A nano tank may only need one nano LED light, like the AI Prime HD, but larger tanks may need one Ecotech Radion LED every 2 feet. Advanced features include: Apex ready, web/app control, precision color and intensity control, and customizable mounts.
Midrange led fish tank lights may be a fixture, like the Current USA Orbit Marine LED Pro or AquaMaxx Nemolight, and will have features like an aquarium moonlight, moderate power and control that supports, but may not support app control, deep tanks, or sensitive species.
Entry level led lights may only support low light corals and have basic controls. They offer the beauty, shimmer, and efficiency of led for fish only and perhaps soft coral aquariums.
