How to use
Install the UMAX UB903 by screwing it into a compatible standard lamp socket and ensure the power is switched on.

Usage recommendations
Place the bulb in fixtures where Wi‑Fi signal strength is adequate; avoid locations with poor reception. For reliable performance, use a stable 2.4 GHz Wi‑Fi network if the app specifies frequency requirements.
