10 Best LED Refugium Lights : 2021 Buyer’s Guide

Best led refugium light

There is a variety of lights available to aquarium hobbyists, and these (lights) often vary in their capabilities. While some just serve as a source of illumination, others do much more, and an example of such is the refugium light.

The refugium, being a place where macroalgae are grown for the purpose of filtration, requires a considerable amount of illumination similar to the planted aquarium lighting.

More so, some other plants can also be grown within the refugium. To this end, having a LED refugium light around it is essential for promoting the process of photosynthesis which, in turn, helps in ensuring that the macroalgal mass and/or plants [within the refugium] thrive(s). Moreover, with its installation, the growth of macroalgae continues to come rain and sunshine.

In essence, a good refugium light provides illumination, advances photosynthesis and indirectly aids the filtration process in the tank; all these activities/functions make for a hygienic and vibrant aquarium setup which is the pride of every aquarist.

However, while there are a host of refugium lights out there, it is of utmost importance to let you know that there are only a few that can be set apart among the best.

In view of the above, we have elected to share with you 10 of the best refugium lights in the market today, and we hope that you will find one that will satisfactorily meet your needs and budget as you read on.
