Description

The Yeelight Mercury is a round white smart ceiling light that brings warm-to-cool tunable white light to any room without a separate hub. The light dials steplessly across a 2700–6500 K range — from a cosy warm white to a bright daylight white — and brightness is fully adjustable from 0 to 100 per cent. It connects directly over Wi-Fi and is controlled through the app, voice or a wall switch. Choose from three sizes — C300, C380 and C480.

Tunable white from warm to daylight

The Mercury offers stepless tunable white across 2700–6500 K, so the same fixture delivers a relaxed warm white in the evening or a crisp daylight white for work. Brightness adjusts smoothly from 0 to 100 per cent.

Three sizes for every room

The C300 (30 cm) suits bedrooms and studies, the C380 (38 cm) covers a medium room of roughly 20–25 square metres, and the larger C480 (48 cm) is rated for a living or dining area of around 30–35 square metres.

Works with your smart home, no hub needed

The Mercury connects directly over 2.4 GHz Wi-Fi with no gateway required, and uses Bluetooth for setup. It is controlled through the Yeelight or Xiaomi Home app, a wall switch or voice, and works with Google Home, Amazon Alexa, Samsung SmartThings and Xiaomi Mi Home. Please note the Mercury does not support Apple HomeKit — if Apple Home is essential, consider the Yeelight Ultra-Slim line instead.

Installation and Singapore warranty

The Mercury is an indoor, surface-mount ceiling light that runs on 220–240 V ~ 50/60 Hz mains and replaces an existing ceiling light point. Every unit sold by PassionHome is backed by a 24-month local Singapore manufacturer warranty.
