HOW TO FIND LIFX LIGHT BULB MAC ADDRESS USING ITS SERIAL NUMBER


Each LIFX bulb has a Wi-Fi chip, and a unique MAC address. The MAC address is printed right on the bulb base, and it's also the bulb's serial number. A MAC address is a 12 digit number. For a bulb with serial number D07123456789, the MAC address would be D0:71:23:45:67:89. Currently, all LIFX lights have a MAC address beginning with D073D5. The last six digits of the MAC address are broadcast as part of the LIFX Wi-Fi network during setup.
