Smart Bulbs | Products

Overview

SGT Smart Bulbs are Wi-Fi and Zigbee colour-changing LED bulbs that drop into any standard E27 / B22 / E14 fixture and instantly bring the room online — app control, voice control, schedules, scenes, and per-bulb energy reporting in a single fitting.

Built for homes and small offices that want intelligent lighting without rewiring. Bulbs commission in under a minute by QR code, join the local hub or your existing Matter network, and start responding to taps, voice commands and sunrise/sunset triggers right away. The same bulb does 16 million colours, full tunable white from 2200 K to 6500 K, and dimming down to 1 %.

16M colours + tunable white 2200–6500 K in a single bulb
Wi-Fi 6, Zigbee 3.0 and Matter — works with any major ecosystem
Schedules & circadian scenes — sunrise wake-up, sunset wind-down, do-not-disturb
Per-bulb energy meter — real watts logged to the cloud, no extra plug needed

How It Works

The diagram above shows how a command travels from a tap, voice or schedule all the way to the bulb in under 50 ms. Hover any module to see its live telemetry.

The bulb — a tri-channel RGBWW LED driven by a low-power Wi-Fi/Zigbee SoC, with a built-in current sensor for real-time energy.
Radio & hub — bulbs join your router directly (Wi-Fi/Matter) or relay through an SGT Hub for Zigbee mesh and offline-resilient control.
Cloud & analytics — schedules, scene library, energy history and sunrise/sunset calculations run in the cloud and sync to every bulb.
Family & scenes — everyone in the household uses the app, voice assistant or a wall scene-button; geofencing turns lights on as someone arrives.

The amber stream along the bottom of the diagram is the continuous command channel — new scenes, colour changes and dim levels flowing back to every bulb in real time.
