How to Find Your LIFX Bulb Address in 4 Easy Ways [2024]

Key Takeaways
  • Identifying MAC Address: The MAC address can be found directly on the bulb's base, labeled as a serial number, or via the LIFX app by checking the light settings.
  • Finding IP and MAC Addresses: Use your Wi-Fi router's web interface or app to view connected devices for both IP and MAC addresses, or employ command lines in Terminal or Command Prompt for the same.
  • Resetting LIFX Bulbs: For connectivity issues, reset the bulb by turning it on and off five times at consistent intervals until it flashes, indicating a successful reset, then reconfigure it using the LIFX app.

LIFX light bulbs are actually smart LEDs that are Wi-Fi enabled. You could easily control the lights and change their color, brightness, and effects remotely by using the LIFX app on your phone or with the help of voice assistants like Google, Alexa or Siri.

Every LIFX light bulb has its own unique MAC and IP address, and sometimes you might need to know them for various reasons. In this article, we are going to show you how to do that in different ways.

Why Do You Need to Find LIFX Light Bulb Address?

There are really two different addresses that people ask about when it comes to LIFX light bulbs. One is the IP address, while the second is the MAC address. A MAC address is a unique identifier given to the LIFX smart LED bulb by the manufacturer, while the IP address is a label given to it by the router it is connected to. Some of the reasons you might need either of these are:

  • To assign a static IP to your LIFX bulb to help with network stability and security.
  • If you use a MAC filter to prevent unauthorized devices from connecting to your network, you might need the MAC address to add the bulb to the list of allowed devices.
  • You want to troubleshoot your LIFX smart light because it’s unresponsive.

1. Finding MAC Address at The Base of The LIFX Bulb

Since each LIFX light has a Wi-Fi chip, it has a specific MAC address. At the base of all LIFX light bulbs, a serial number is mentioned, usually denoted by “S/N”, followed by a 12-digit combination of letters and numbers.

The serial number is the MAC address of the bulb, the only difference being the format. For example, if your serial number was D07123456789, the MAC address for this device would be D0:71:23:45:67:89.

2. Finding MAC Address Using the LIFX App

Here’s how you can find the MAC address of any LIFX bulb in your home within the app:

  1. Launch the LIFX app, and from the home section, open the bulb whose MAC address is needed.

    In LIFX app, open bulb.
  2. Tap on the three dots in the top right corner to open “Light Settings”.

    Tap on the three dots to open Light Settings.
  3. Scroll down to the bottom to find the Serial of your bulb, which can be converted to MAC address by adding a colon after every two digits. For example: D073D5123456 → D0:73:D5:12:34:56

    The serial number is the MAC address

3. Finding IP Address and MAC Address Using the Wi-Fi Router

The web interface or app of every router is a bit different, but the steps are almost similar in each case. Here is a general guide:

  1. Ensure that your computer or smartphone and the LIFX bulb are connected to the same Wi-Fi network.

  2. Login to your Wi-Fi router settings page either from the app or by entering the IP address into a browser. You can find this IP address, as well as the login details, at the base of your Wi-Fi router.
