Chihiros WRGB II Slim 120

The Chihiros WRGB II Slim 120 is a powerful and refined RGB LED lighting system designed for 120 cm planted aquariums. Combining advanced WRGB spectrum technology with a slim, modern profile, this fixture delivers excellent plant growth performance and vibrant color rendering for medium to large aquascapes.

Equipped with dedicated white, red, green, and blue LEDs, the WRGB II Slim 120 produces a balanced and customizable full-spectrum output optimized for aquatic plants. Enhanced red and blue wavelengths promote efficient photosynthesis while intensifying plant pigmentation. Stem plants such as Rotala, Ludwigia, and Alternanthera develop deeper red tones, while carpeting plants like Monte Carlo and Hemianthus callitrichoides grow compact and dense under its strong PAR output.

The Slim version provides high light intensity while maintaining a more streamlined and energy-efficient design compared to Pro models. It is ideal for high-tech planted aquariums when paired with CO₂ injection and balanced fertilization, supporting healthy growth, tight internodes, and vibrant aquascape contrast.

Designed specifically for 120 cm aquariums, this fixture ensures wide and even light distribution across the entire tank length. The optimized beam angle minimizes shadowing and promotes uniform development from foreground carpets to tall background stems. It also provides sufficient penetration for moderately deep aquariums.

The durable aluminum housing ensures efficient heat dissipation and stable long-term operation. Its sleek and minimalist design complements rimless aquariums and professional aquascaping layouts, maintaining a clean and modern aesthetic.

The integrated Bluetooth controller connects seamlessly to the Chihiros mobile app, allowing full customization of RGB channels, brightness levels, and programmable lighting schedules. Users can simulate sunrise and sunset transitions, fine-tune spectrum balance, and optimize intensity to enhance plant coloration while managing algae risk.

Ideal for large Nature Aquariums, Dutch-style planted tanks, and advanced aquascaping layouts, the Chihiros WRGB II Slim 120 delivers powerful illumination and flexible spectrum control in an elegant, slim design.
