Add a broader actinic spectrum and dramatic coral fluorescence with the Orphek OR4 iCon UV/Violet Reef Aquarium LED Bar.

Unlike the Violet model, which concentrates primarily on the 420–430 nm range, this UV/Violet model combines three wavelength groups from approximately 390–430 nm. It supplements full-spectrum reef fixtures with near-UV and violet wavelengths that help reveal fluorescent pigments and support coral coloration.

Use it alongside an Orphek Natura iCon, Atlantik iCon or another reef light, or combine multiple OR4 bars for a customized lighting system.

UV/Violet Spectrum

The OR4 iCon UV/Violet combines:

• 390–400 nm near-UV

• 400–415 nm violet

• 420–430 nm violet/actinic

This spectrum is ideal for:

• Enhancing fluorescent coral pigments

• Supplementing full-spectrum reef lighting

• Adding near-UV and violet wavelengths

• SPS, LPS, soft coral and mixed reef aquariums

• Dawn, dusk and evening lighting periods

• Customized multi-bar lighting systems

Intelligent iCon Control

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

Features include:

• Programmable schedules

• Adjustable overall intensity

• Sunrise and sunset transitions

• Sun and Moon Synchronization

• Seasonal calendar programming

• Time-offset control

• iOS and Android compatibility

• Integration with compatible Orphek iCon lighting

Each OR4 bar operates as one dimmable channel. The entire bar dims together; individual wavelength groups are not independently adjustable. Multiple compatible bars may be controlled independently through the app.
