Corals and other photosynthetic marine life require proper light intensity and quality to thrive in the home aquarium.

No matter if you’re keeping a nano reef tank or a mega reef system, high-quality lighting is nothing to skimp on.

But what’s high quality really mean? We’ll guide you through the latest reef-ready LED fixtures, so you’ll be able to choose the right light for your reef aquarium.

What’s the Big Deal About LED Reef Lighting?

Just in case you’re new to the hobby or jumping back into it, LED aquarium lighting has taken over as the lighting of choice for most coral enthusiasts.

Why? Here are the main reasons.

  1. Light Emitting Diodes (LEDs) are energy efficient. In the old days, reef lighting could boost your electric bill by $100 a month! That’s because old-fashioned fluorescent ballasts used a lot of energy.
  2. Unlike fluorescent bulbs, LEDs last for years. Even better, their output does not drop like T-5 and T-8 bulbs. You had to replace your fluorescent tubes once a year to keep the same output. If you ordered special reef bulbs by mail, you hoped none of them would be shattered in shipping.
  3. LED aquarium lights don’t add heat to the aquarium water like traditional reef lighting. With metal halides and fluorescent lighting, almost everyone had to have a chiller on their tanks just to keep the water safe for the corals.
  4. LED reef fixtures often let you adjust the intensity and color spectrum. Some reef fixtures even have automatic sunrise and sunset times that slowly adjust the lighting to match natural reef lighting cycles.

There are other features that we’ll look at as we review the top LED lights for reef aquariums!

Final Thoughts

The LED reef lights in this review fall into two categories.

The Hipargero and Viparspectra lights offer an economical way to get your coral tank up and running.

These fixtures get the job done but don’t have the benefits of daisy chaining, apps, and advanced programming. For many reef-keepers, these lights are perfect for their needs.

If you want to get the latest technology in reef lighting and plan on using several lights over your reef tank, the Ecotech, AI and Kessil reef lights are sure to satisfy you and your corals’ thirst for great lighting.
