The Lights I Tested

The [Hygger Auto On Off Submersible Aquarium Light](https://www.amazon.com/s?k=Hygger+Auto+On+Off+Submersible+Aquarium+Light&tag=thetestedhub-20) is my planted tank pick. PAR output at 14 inches is enough to keep medium light plants growing without supplementation.

I compared five submersible aquarium lights in my freshwater and planted tanks to see which ones actually grow plants and look good underwater.

How we test

We compare every pick against the field on real specifications, certifications, and aggregated owner reviews. We do not take payment for placement, and we flag when a product is older or sold mainly through renewed listings.

FAQs

Are submersible LED lights safe long term?

Yes, if they carry an IP68 rating. I would not trust an IP67 light past a few months underwater.

Will these lights grow live plants?

Low and medium light plants like java fern and anubias thrive under any of these. High light carpeting plants want a dedicated planted tank fixture.
