Reef Compatibility

With 36W and a PAR of ~100 at 12 inches, the Halo is suitable for all types of corals: soft corals (zoanthids, mushrooms, leathers), LPS (hammer, torch, frogspawn, acan), and easy SPS (Montipora, Stylophora). Many aquarists report success with Acropora under the Halo at approximately 50% intensity. The Halo is the lighting recommended by Reef Casa for Studio 12, Pico 6, and Tide 12 aquariums.

Compatible Aquariums

With its 18" x 18" coverage, the Halo perfectly covers Reef Casa Pico 6 (16" x 15") and Studio 12 (16" x 15") aquariums. For the Tide 12 (22" x 20") and Laguna 24 (22" x 20"), the Halo covers the central area but leaves the corners less illuminated—the Manta 75W with 24" x 24" coverage is preferable for these models.

Frequently Asked Questions

Can the Reef Casa Halo grow SPS corals?

Yes. The Halo produces 36W with a PAR of ~100 at 12 inches. Many aquarists successfully keep Montipora, Stylophora, and even Acropora under the Halo. For very light-demanding SPS, place them in the upper half of the aquarium and increase the intensity above 50%.

What is the difference between the Reef Casa Beam and Halo?

The Beam is an 18W (6 LED) on/off light without a timer or dimmer, for soft corals and LPS. The Halo offers 36W (12 LEDs), a built-in timer with sunrise/sunset, a dimmer, and 3 adjustable color channels. The Halo is suitable for all corals, including SPS, and covers an 18" x 18" area compared to 15" x 15" for the Beam.

Is the Halo shroud included?

No. The Halo shroud is sold separately. It blocks side light, directs it downwards, and protects your eyes. It is especially recommended if you view your aquarium while seated at light height, for example, at a desk.
