Good to know

Installation is simple: screw the bulb into any E14 socket, download the Lepro+ app, and follow the pairing instructions. The bulb works only with 2.4GHz Wi-Fi networks, so ensure your router broadcasts that band. No separate hub or bridge is needed. For best performance, keep the bulb within range of your Wi-Fi router. The bulb is not suitable for use with dimmer switches—use app or voice dimming instead. It operates safely in temperatures from -20°C to 40°C, making it suitable for enclosed indoor fixtures.
