WRGB II 120

The WRGB II 120 LED luminaire represents a specific catalog identity within the WRGB II product family designed by Chihiros for freshwater planted aquariums. The official page marks it discontinued and display-only; this profile preserves the original regular model without substituting 10th Edition data. The series was engineered to deliver comprehensive spectral blending tailored to promote aquatic vegetation growth and accentuate natural coloration throughout the aquascape. In official manufacturer records, the product page for the original classic WRGB II series is designated as discontinued and preserved for display purposes only. The WRGB II Slim profile is designed for planted tanks with reduced power demand and a broad light spread, officially characterized by roughly 40–50% less brightness performance compared to the standard WRGB II baseline. The newer 10th Edition series incorporates different LED packages that produce higher luminous flux, which must not be conflated with legacy model ratings. This editorial profile adheres strictly to verified manufacturer data, omitting uncertified measurements, hypothetical radiation charts, and guaranteed biological outcomes.

The optical system utilizes RGB 3-in-1 LED packages wherein individual emitter modules combine dedicated red, green, and blue elements. Color balancing and overall dimming are managed through the My Chihiros mobile application via the built-in Bluetooth controller integrated directly into the luminaire. The software allows users to customize color spectrum ratios and schedule automated sunrise and sunset transitions to simulate natural photoperiod curves. Official product documentation outlines only Bluetooth app control; there is no native Wi-Fi connectivity, remote cloud functionality, standalone hardware timer, voice assistant integration, or published Bluetooth protocol version. From a husbandry standpoint, illumination adjustments should be approached with caution: aquarists are advised to start with conservative output levels and implement intensity or photoperiod changes gradually while observing plant adaptation, algae development, and livestock health, as individual aquatic systems exhibit unique environmental balances.

Selecting the appropriate fixture requires careful evaluation of the metrics published on official Chihiros specification graphics. The model designation WRGB II 120 identifies the precise configuration in the WRGB II range, with catalog availability outlined by the The official page marks it discontinued and display-only; this profile preserves the original regular model without substituting 10th Edition data notation. The item number 331-91201 confirms the exact catalog identity. Intended aquarium width is specified by the 120–140 parameter, which pairs with physical body dimensions of 1200 × 140 × 18 mm. The supplied mounting hardware accommodates glass thickness up to 12 mm where explicitly stated. Illumination is generated by 120 individual RGB 3-in-1 LED components, yielding a rated luminous flux of 7700 lm with a rated electrical power consumption of 130 W, backed by a published ingress rating of IP43. Luminous flux in lumens measures visible light output weighted to human optical sensitivity and must not be treated as a direct substitute for photosynthetically active radiation or used to infer unmeasured photosynthetic benchmarks.

Proper installation requires confirming that the aquarium length falls within the range indicated by 120–140 and that tank wall thickness does not exceed the 12 mm rating of the mounting legs. When evaluating model families, the WRGB II Slim differs from classic WRGB II by its lower-profile housing and roughly 40–50% less brightness performance, whereas the 10th Edition introduces revised LED hardware. Regarding service components for legacy units, Chihiros notes that the original standard controller is discontinued; a 10th Edition controller can serve as a functional replacement, but the My Chihiros app will recognize it as a 10th Edition unit and color rendering characteristics may vary, making prior compatibility verification essential. Optional glare shades, available in model-matched lengths of thirty centimetres, forty-five centimetres, or two sixty centimetre sets for extended fixtures, attach to the front and rear edges to minimize ambient room reflection without altering official photon metrics.

The lighting unit must be mounted exclusively over structurally stable, open-top aquariums using the appropriate factory legs or brackets designed for the fixture. The metallic housing acts as a passive heatsink that relies on open convection, requiring unobstructed airflow across the upper cooling fins and strict avoidance of enclosed aquarium hoods. The external power supply module and electrical connections must be situated in a dry location elevated away from water splash, ambient humidity, and condensation zones. A drip loop must be formed in the power cord below the level of the wall outlet to prevent stray moisture from traveling along the wire into electrical sockets. Following secure physical placement on the tank rim, connect the power cord and launch the My Chihiros app to complete initial pairing and Bluetooth setup.

The published IP43 rating denotes basic protection against solid foreign objects and light water spray falling at limited angles, but it must never be construed as an immersion rating or permission to expose the housing or power components to heavy moisture or submersion. Always disconnect the power supply from the wall receptacle before performing routine wipe-downs, physical handling, or mechanical bracket adjustments. The exterior aluminum housing and optical surface should be cleaned only with a soft, dry or lightly dampened cloth using fresh water, avoiding chemical detergents, alcohol, or abrasive cleaning compounds. The manufacturer does not establish mandatory maintenance timetables; users should perform visual checks and cease operation immediately if damage to the power cord, electrical connector, power brick, or aluminum chassis is observed.

Core advantages of the platform include vivid RGB 3-in-1 color rendering tailored for planted layouts, silent passive aluminum thermal management, automated sunrise and sunset scheduling via mobile software, and optional matching shades to control room glare. Practical boundaries include reliance on short-range Bluetooth connectivity and smartphone software in the absence of onboard manual controls, the discontinued status of original classic WRGB II models and legacy controllers, and the roughly 40–50% lower output performance of Slim variants. The official warranty provides one-year limited coverage from receipt under normal operation following manual guidelines. Water damage resulting from improper mounting, splashing, or immersion is excluded, unauthorized disassembly or modification voids the warranty, and replacement parts are not covered by standard warranty terms. The one-year warranty duration must not be interpreted as an estimate of total operational lifespan.
