CHIHIROS WRGB II PRO LED LIGHT
The Chihiros WRGB II Pro is a professional-grade full-spectrum LED aquarium light for high-tech planted tanks, using advanced 4-in-1 WRGB chips and Bluetooth app control to deliver high-PAR growth power and stunning colour in a razor-thin aluminium body.

Which tanks is it best for?
The WRGB II Pro is built for high-tech planted aquariums and demanding plants — carpets, red plants and dense aquascapes — run with CO2 and a full dosing routine. Its high PAR and 4-in-1 chips deliver both growth and colour. For a slimmer, lower-output option see the WRGB II Slim, and to hang it open-top add the WRGB 2 Pro hanging kit. Read our planted aquarium lighting guide.
How to use it
Mount the light on its stainless legs or hang it, pair it in the My Chihiros app, and set an 8–10 hour photoperiod with CO2 (start lower) and gradual sunrise/sunset. Because it is high-output, watch for algae and keep light, CO2 and nutrients in balance. Always include a dark night period; do not immerse the light or adaptor; use a drip loop.
