How to restore the factory setting for the bulbs?
  1. Power on the bulb.
  2. Wait 3-5 seconds and then power off the bulb.
  3. At the end of the 4th time when you turn on the bulb, it will emit strobe for a few seconds. After that it will become fully bright at which point the reset is complete. Once you have reset the bulb, you should be able to see its wifi IP "LEDnet******" again under your mobile device's wifi settings. (if not, please restart your wifi, wait for a while and you will see it).
