Where you'd use it
Colour scenes for entertaining
Switch the bulb to full RGBW colour for a party or film night, then set it back to tunable white for everyday use, all from the same fitting via the app or scripted scenes.
Soft night-time lighting
Use Night Mode to keep the bulb at a low, comfortable brightness for late-evening trips to the kitchen or bathroom without a jarring full-brightness switch-on.
Per-bulb power tracking
Check the real-time power monitoring on an individual lamp to confirm it's actually switching off when scheduled, rather than assuming from the app state alone.
