Zetlight S1 Spotlight (Bluetooth & Wi‑Fi)

Zetlight S1 Spotlight – Precision Lighting for Natural Aquascapes

The Zetlight S1 Spotlight recreates the gentle, shimmering quality of sunrise in a rainforest, delivering a focused beam that highlights the natural beauty of biotope aquariums. Its compact design houses a powerful 9W 5000‑6000K COB LED, providing bright, even illumination that reaches the tank bottom while consuming minimal energy.

Thanks to a smooth zoom ring, you can instantly adjust the light’s focus from a tight 10° spotlight to a wider 60° spread. The innovative diamond‑shaped hemispheric cellular lens maximises light penetration, and the flexible gooseneck with a 90° adjustable shooting angle lets you position the light exactly where it’s needed. Seamlessly manage settings with Bluetooth or Wi‑Fi through the Horizon Aqua app, giving you full control from your smartphone.
