Overview for Refugium Lighting The Ultum Nature Systems Refugium Light is a compact, submersible LED designed to support macro algae and photosynthetic life in saltwater setups

Its full-spectrum output is tailored to Chaeto (Chaetomorpha) and other common refugia greens like pom-pom, red ogo, and sea lettuce, helping you create steady, energy-efficient lighting in nano tanks or sump refugia

Flexible mounting for diverse setups Clip-on mount with a gooseneck allows versatile positioning around tank rims or sump edges

Magnetized mount provides a secure, hands- option near metal surfaces in sumps or behind tanks

Spectrum, color options, and control Eight dimmable LED colors give you room to tune the atmosphere and spectrum for various growth stages or viewing preferences

An inline remote keeps brightness, color, and timer adjustments within arm’s reach, whether you’re refining coral health or balancing nutrient needs

Durability and design details Constructed with waterproof materials, this small light remains submersible in demanding saltwater environments

Its compact footprint (7

28 x 2

05 x 0

51 inches) fits neatly in sumps, refugia, or tight display tanks without crowding other equipment

Practical use cases and -life setup ideas In a nano reef, the light can illuminate Chaeto as it sways with gentle water movement, aiding visible macroalgae growth and nutrient management

In a sump refugium, mount the unit along the edge for consistent coverage that supports macroalgae health

The day-night cycle created by the included timer can provide a natural rhythm that many hobbyists find visually appealing while keeping algae conditions manageable
