The Chihiros WRGB II Pro is the high-performance, professional-grade powerhouse of the Chihiros linear LED catalog. It is engineered specifically for deep high-tech aquariums and intense aquascapes featuring the most demanding, light-hungry red stem plants or thick foreground carpeting flora.
The major structural upgrade in the Pro series is the transition to cutting-edge 4-in-1 WRGB LED chips. While older setups grouped colors onto separate, alternating diodes, the Pro clusters its white, red, green, and blue components into a single unified lens architecture. This technology creates a completely blended, shadowless light field with zero color separation while generating up to 40% more raw brightness and PAR intensity than the standard WRGB II model. It easily pushes usable energy through deep water columns exceeding 50 cm.
The fixture features an integrated Bluetooth controller built directly into the matte-black anodized aluminum unibody shell. Connecting natively to the My Chihiros mobile app on iOS and Android devices, it removes any need for separate inline modules or wall timers. The app provides 1% increments of fine-tuning across the independent red, green, blue, and white channels alongside 24-hour photoperiod scheduling and automated, smooth sunrise/sunset ramping. The heavy metal casing functions entirely as a silent, passive thermal dissipation grid and carries an IP43 water-resistance rating.

Core Hardware & Operational Features
-
True 4-Way Color Mixing: The My Chihiros app breaks down spectrum control into independent White, Red, Green, and Blue adjustment sliders. This dedicated white channel allows you to increase raw visual daylight brightness without distorting or over-saturating the specific color balances of your layout.
-
Heavy-Duty Metal Stand Bars: Ships with a pair of adjustable stainless steel side mounting legs that slide out horizontally from tracks on either side of the aluminum chassis. These brackets lock securely over glass tank rims using plastic thumbscrews to adjust for non-standard aquarium footprints.
-
Fanless Silent Architecture: The deeply grooved, thick aluminum casing distributes heat effectively across the entire top surface. This passive configuration operates completely silently while protecting internal circuits from damp conditions without using failure-prone active cooling fans.
-
What's Shipped inside the Box: Each factory kit contains 1x WRGB II Pro series black anodized aluminum LED panel with its internal Bluetooth receiver, 2x adjustable sliding stainless steel mounting rod leg sets, and 1x multi-voltage external desktop power supply brick with a localized wall plug cable.
