Chihiros WRGB II Pro 120

The Chihiros WRGB II Pro 120 is a high-performance RGB LED lighting system engineered for 120 cm planted aquariums. Designed for serious aquascapers and large high-tech setups, this professional fixture delivers exceptional light intensity, advanced spectrum customization, and superior color rendering to maximize plant growth and aquascape vibrancy.

Built with advanced WRGB LED technology, the WRGB II Pro 120 combines white, red, green, and blue diodes to generate a powerful and well-balanced full-spectrum output. 

This optimized spectrum enhances photosynthesis efficiency while significantly intensifying red plant pigmentation and deepening green tones. Demanding species such as Rotala, Ludwigia, Alternanthera, and carpeting plants like Monte Carlo and Hemianthus callitrichoides develop dense growth, compact structure, and rich coloration under its high PAR output.

The Pro version offers substantially higher intensity compared to the standard WRGB II models, making it ideal for deep tanks and aquariums requiring strong light penetration. When paired with CO₂ injection and proper fertilization, the WRGB II Pro 120 supports vigorous plant metabolism, tight internodes, and dramatic color contrast across the entire layout.

Designed specifically for 120 cm aquariums, this fixture provides wide and uniform light distribution from end to end. The powerful LED configuration minimizes shadowing and ensures consistent illumination across foreground carpets, midground plants, and tall background stems.

The durable aluminum body ensures efficient heat dissipation, maintaining stable performance even during long photoperiods. Its sleek, minimalist design complements rimless aquariums and high-end aquascaping displays.

The integrated Bluetooth controller connects to the Chihiros mobile app, allowing full control over RGB channel intensity, brightness levels, and programmable lighting schedules. Users can simulate sunrise and sunset effects, fine-tune spectrum balance, and adjust output to optimize plant growth while managing algae risk.

Ideal for large Nature Aquariums, Dutch-style layouts, and advanced Iwagumi compositions, the Chihiros WRGB II Pro 120 provides professional-level lighting performance for aquarists seeking maximum plant coloration and growth efficiency.
