💡【Voice Control】Refoss smart bulb is compatible with Apple HomeKit (iOS 13 or Android 6.0 or later), Apple Watch, Alexa Echo, Echo Dot, and Google Assistant. Just say "Hey Siri, turn off the light bulb." No worries about having your hands full turning on the light or leaving home with the light on. 💡【Apple HomeKit Remote Control】Please note that if you use the Apple Home app to remotely control the smart light bulb, you need to have an Apple Hub device at home. If you don't have these devices, you can still control the LED bulb anytime and anywhere via the Refoss app without needing a hub. Note: only works with 2.4GHz WiFi. 💡【Saving Energy and Money】My dear, saving energy can start with smart LED bulbs. Our smart bulb is 9W (equivalent to the brightness of a regular 60W bulb), estimated energy cost: 0.0018 kWh per hour. 💡【Adjustable Light for Eye Comfort】To simulate natural light in various scenes and relieve eye fatigue while lighting, we use a dimmable design with a range of 0-810LM. The temperature of the dimmable light ranges from warm light (2700K) to cool light (6500K). The RGBCW (RGB mixed with cool and warm light) provides a wide variety of options. 💡【16 Million Colors】With 16 million colors available, create the perfect ambiance to impress your friends!
