Chihiros B45 Series WRGB LED Aquarium Light

The Chihiros B45 Series LED Aquarium Light is a slim, powerful WRGB light designed for aquariums approximately 45–65cm wide. Combining white and RGB LEDs, it delivers a balanced full-spectrum output that supports healthy aquatic plant growth while bringing out the natural colours of fish, plants and hardscape.

With a sleek 12mm-thick aluminium body and fanless passive cooling, the B45 keeps a clean, low-profile appearance above the aquarium. Producing up to 1,747 lumens from 28.9W, it offers an excellent balance of performance, efficiency and affordability for planted aquariums and everyday display tanks.

The included Bluetooth controller connects the light to the MyChihiros app, allowing you to control brightness, create daily lighting schedules and program gradual sunrise and sunset effects directly from your smartphone.
