There are two charging methods for rechargeable light bulbs, namely type-c and lamp holder. Equipped with a 2600mAh battery, type-c charging only takes 6-8 hours and can be used continuously for 7-20 hours. When charging, the red light is on, and when fully charged, the blue light is on. When the lamp holder is charged, it turns into an ordinary LED bulb, automatically storing power during daily use and providing you with lighting in emergencies. The rechargeable LED bulb has a brightness of 9W and a lumen count of up to 900ml, which can meet the daily lighting needs of the home. （ For larger houses, it is recommended to buy two or more）The magic light bulb also has three adjustable color temperatures, allowing you to adjust the atmosphere of different color temperatures according to different usage scenarios. There are two working modes. One is to turn on/off and adjust the color temperature and brightness of the bulb through the touch switch on the lamp body. The other is to control all functions of the battery-powered light bulb through the remote control, including on/off, color temperature adjustment, brightness adjustment, 15~60 minute timer function and BL emergency light mode. After pressing the BL button, the wireless light bulb will turn on the emergency mode and automatically light up to provide you with lighting in the event of a sudden power outage.
