Promote vigorous macroalgae growth and illuminate mangroves, seagrass and planted refugiums with the Orphek OR4 iCon Red Plus Grow & Refugium LED Bar.

The Red Plus uses a specialized orange, red and infrared spectrum of approximately 520–740 nm. It is designed for refugiums and planted filtration systems rather than as the primary light for a coral display aquarium.

Use it to illuminate Chaetomorpha and other macroalgae, support nutrient-export systems or provide targeted lighting for mangroves and seagrass.

Specialized Grow and Refugium Spectrum

The broad 520–740 nm spectrum is optimized for photosynthetic plant and macroalgae growth.

Ideal applications include:

• Chaetomorpha and other macroalgae

• Reef aquarium refugiums

• Mangroves and seagrass

• Planted filtration systems

• Algae scrubbers and propagation systems

• Supplemental horticultural-style aquarium lighting

Healthy macroalgae growth can support nutrient export by consuming available nitrate and phosphate as the algae develops and is harvested.

Intelligent iCon Control

The included iCon dimming driver provides Wi-Fi and Bluetooth connectivity through the Orphek iCon app.

Features include:

• Programmable lighting schedules

• Adjustable overall intensity

• Sunrise and sunset transitions

• Sun and Moon Synchronization

• Seasonal calendar programming

• Time-offset control

• Integration with compatible Orphek iCon lighting

• iOS and Android compatibility

Each OR4 bar functions as one dimmable channel. The complete bar dims together; individual LED colors are not independently adjustable.

Selecting the Correct Size

Choose the bar that most closely matches the illuminated length of your refugium or planted aquarium. Multiple bars may be combined when greater coverage or intensity is required.

Begin at a moderate intensity and adjust the lighting period gradually according to macroalgae or plant response.
