Our take on the Aquarium Systems Proten LED Reef Blue Fish Aquarium Striplight 20 Watt 24-in

The Proten LED Reef Blue is a 20 W, 24-inch blue LED striplight in an aluminum housing, built to add actinic blue light to a saltwater or reef tank. It is a supplement rather than a full-spectrum main light: the blue output is meant to bring out fluorescent colors in corals and fish and to support dawn and dusk viewing. Compared with full-spectrum reef fixtures, it lacks white channels and built-in dimming or programming, so most reef keepers pair it with a main light or a timer. It suits nano and small reef owners who want a slim, low-profile blue bar over a 24-inch tank.

Pros
  • Blue actinic output makes fluorescent corals and fish colors pop
  • Slim aluminum body sits low over open tanks
  • Simple on/off operation, no programming needed
  • 24-inch length matches common nano and small tank footprints
  • Low 20 W draw for a supplemental bar
Cons
  • Blue only, so it cannot serve as a tank's main full-spectrum light
  • No built-in dimmer, timer or ramp control
  • Not rated for the spread of a wide or deep tank on its own
  • Little published detail on LED lifespan and spectrum

Questions and answers

Can this light be the only light on a reef tank?
No. It is a blue actinic supplement, not a full-spectrum main light. Corals need white and full-spectrum output for growth, so pair it with a main reef fixture.
What size tank does the 24-inch version fit?
The bar is 24 inches long, which suits nano and small tanks of roughly that footprint. On wider tanks it covers only part of the surface, so you may need more than one.
Does it have a timer or dimmer?
No. It runs as a simple on/off light, so use an external timer or controller if you want a dawn-to-dusk schedule.
Will it make my corals fluoresce?
Blue actinic light brings out green, orange and other fluorescent pigments in many corals and fish. The effect is strongest in a darkened room with the main white light off.
Is it safe over a saltwater tank?
The aluminum housing is aimed at aquarium use, but keep splashes and salt creep off the fixture and mount it clear of the water surface.
Where is the Aquarium Systems Proten LED Reef Blue Fish Aquarium Striplight 20 Watt 24-in cheapest?
At Chewy, for $167.69, as of our latest check.
