Editor's Notes

September 14, 2019:

While many aquarium lights conveniently can be placed above your tank, some fish owners prefer to use a fully submersible model, which are generally easy to install and can save you some precious space when your setup is in a tight corner.

Joining our selection in today’s update is the Hagen Fluval Prism 2.0, which casts a powerful 6.5-watt beam that can project up to a generous six feet. (For those looking for a more subdued effect, it does offer brightness control.) It comes with a handy remote that enables you to choose from several fun special effects, including sunsets, storms, heavy storms, and the full color cycle. Its LED technology provides for a lengthy lifespan of up to 50,000 hours. It features a compact, unobtrusive, housing that is easy to conceal behind other elements of your tank, with a conveniently rotatable head.

The affordable Nicrew comes in three sizes, and this energy-efficient choice emits a blue and white glow, and can be positioned just about anywhere inside your tank and held firm with the included suction cups. It features a safe, five-volt output and is backed by a one-year limited warranty.

For something a little more unique and non-traditional, look to the Nicrew Volcano Ornament Kit, which features a mountain-like base made from durable resin, along with a base that sits underneath it with built-in, red LEDs. The resulting effect resembles overflowing lava. It also comes in a multi-colored light design. Either selection will provide a fun, not-overly-large component that will look nice in a corner of your tank.

Leaving the list today are the Bivisen LED and the Goobat Marine, both of which are not available at this time.
