Chihiros WRGB II 90 Anniversary Edition Review: Premium Planted Aquarium Lighting

Introduction

The Chihiros WRGB II 90 Anniversary Edition is one of the most popular LED lighting choices for planted aquariums. This review examines its build quality, light spectrum, app-based customization, and real-world performance in supporting plant growth.

Build Quality and Design

The Chihiros WRGB II features a sleek, modern design with an aluminum body and slim profile finished in matte. The construction feels premium and durable, designed to complement both traditional and contemporary aquarium setups.

The 90 cm model is sized to fit standard 90P tanks and similar setups, providing even light distribution without creating hot spots across the aquarium floor. Aluminum holders and hanging kits are available as separate purchases, making the light adaptable to open-top aquariums or rimless tank configurations.

Light Spectrum and Plant Growth

The WRGB II uses true RGB LED technology to deliver a full-spectrum light output. This spectrum brings out deep reds in stem plants, rich greens in foliage, and brilliant blues that enhance overall plant coloration. The lighting is effective for both aquascaping photography and supporting healthy plant development.

The light supports demanding plant species including fast-growing stems like Rotala and Ludwigia, as well as compact foreground plants like Monte Carlo. Plants grown under this spectrum show vibrant coloration and compact, healthy growth patterns.

App Control and Customization

One of the standout features is Bluetooth control via the Machi Heroes application. The app allows users to set custom light schedules, including sunrise and sunset transitions, and adjust intensity levels throughout the day.

This level of customization enables aquascapers to simulate natural lighting conditions and optimize plant growth cycles without manual adjustments. The app interface is intuitive and provides real-time control from a smartphone.

Power Output and Coverage

The 90 Anniversary Edition delivers 100 watts of power and produces 8,400 lumens, a significant increase over the standard version which outputs 6,200 lumens. This higher output ensures adequate light penetration for deeper tanks and supports more demanding plant species.

The increased power and lumen output make the Anniversary Edition suitable for larger planted setups or tanks with taller plant growth requirements.

Conclusion

The Chihiros WRGB II 90 Anniversary Edition is a top-tier choice for aquascapers seeking high-end lighting with full customization capabilities. The combination of premium build quality, full-spectrum RGB technology, app-based control, and strong power output makes it well-suited for serious planted aquarium enthusiasts.
