How we ranked these

We measured real-world performance in established tanks, weighting reliability and health outcomes at 25%. Value for money counted 20%, covering purchase price and ongoing costs. Availability and support, ease of maintenance, long-term keeper satisfaction, and fit for common tank goals each contributed 15%, 15%, 15%, and 10%, respectively. Data came from hobbyist forums, repeat-purchase patterns, and documented failure modes.

We deliberately ignored marketing claims, unverified PAR charts, and aesthetics not tied to coral health. We also excluded niche or experimental products lacking broad community consensus. This avoids hype and focuses on what experienced reef keepers actually use and recommend. The ranking prioritizes practical, proven solutions over theoretical performance.

What to look for

When choosing between these picks, match the light to your tank's dimensions and target corals. For nano tanks, the AI Prime 16HD offers app control and sufficient PAR. For larger systems, consider multiple units or higher-output fixtures. Always verify the spread and intensity at your tank's depth. Budget for a PAR meter or use a trusted chart to ensure your corals receive adequate light without photobleaching.

The most common mistake is buying based on wattage alone, ignoring spectrum and spread. Many hobbyists overlight small tanks, causing algae blooms and coral stress. Conversely, underlighting large tanks leads to poor growth and coloration. Always measure PAR at the coral placement depth and adjust acclimation gradually. Also, factor in the cost of replacement parts and customer support, which vary significantly between brands.
