Chihiros WRGB II Slim 120 LED Light (90w)

Chihiros WRGB II Slim 120 LED Light (90 W)

Illuminate your aquascape with elegance and precision — the Chihiros WRGB II Slim 120 is a high-performance LED fixture engineered for planted aquariums between 120 and 140cm in width. With its super-slim profile, full-spectrum RGB lighting, and intuitive control features, it delivers both aesthetics and functionality for serious aquarists.

Key Features & Benefits

Ultra-Slim Design
Measuring just 15mm in height, the WRGB II Slim blends seamlessly into your aquarium setup, drawing attention to the plants and hardscape rather than the light itself.

Optimised Full-Spectrum Lighting
Equipped with 80 LED emitters (RGB 3-in-1), this lamp delivers a luminous flux of 4800 lm while consuming 90 W of power. Its balanced spectrum supports healthy plant growth and brings out the vivid colors of fish, leaves, and aquascape elements. 

Smart Wireless Control
No external commander is needed. You can program and adjust the light directly via Bluetooth using the My Chihiros App. The app gives you individual control over red, green, and blue channels and lets you set custom daily cycles (sunrise, peak, sunset).

Wide Coverage & Even Distribution
Despite its compact form, the Slim variant offers excellent beam distribution across the full width of the tank. At relatively low power, it maintains stable illumination without hot spots.

Mounting Flexibility
The included adjustable brackets let you fit the light to various aquarium rim widths. Optionally, the unit can be suspended using a hanging kit (sold separately) for a cleaner floating look. 

Durability & Build Quality
Constructed from sleek black aluminum housing with IP43 splash resistance, it’s made to endure humid environments above open-top tanks (but it’s not recommended to use under sealed aquarium lids).

Usage Tips & Considerations

• Not for use under sealed lids – the Slim series is not well sealed for enclosed environments and may be susceptible to corrosion if used under cover.

• Start at moderate intensity – many users recommend starting at ~ 40–60% brightness to avoid plant burn or algae blooms, then gradually increase as needed.

• Ensure good CO₂ & nutrient availability – high-quality lighting alone isn’t enough; aquatic plants will also need proper CO₂ injection and fertilization for optimal growth.

• Mount height matters – raising the light too far above the water surface will reduce effective light penetration. Aim for a balance between spread and intensity.
