How to Find Your LIFX Bulb Address in 4 Easy Ways

LIFX light bulbs are smart LEDs that are Wi-Fi enabled, allowing you to control their color, brightness, and effects remotely through the LIFX app or with voice assistants like Google Assistant, Amazon Alexa, or Apple Siri. Each LIFX bulb has its own unique MAC and IP address, which you might need for various reasons.

A MAC address is a unique identifier given to the bulb by the manufacturer, while the IP address is assigned by the router it’s connected to. You may need these addresses to assign a static IP for network stability and security, to add the bulb to an allowed devices list if using a MAC filter, or to troubleshoot an unresponsive smart light. In this article, we’ll show you different ways to find these addresses.

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 using the app:

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

   

2. Tap on the three dots in the top right corner to open “Light Settings”.

   

3. Scroll down to the bottom to find the Serial of your bulb, which you can convert to a MAC address by adding a colon after every two digits. For example: D073D5123456 → D0:73:D5:12:34:56

   

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

The web interface or app of each router may differ slightly, but the steps are similar in most cases. Here is a general guide:

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

2. Log in to your Wi-Fi router settings page, either through the app or by entering the IP address into a browser. You can find this IP address and the login details at the base of your Wi-Fi router.

   

3. Once logged in, look for a section that shows the list of devices connected to your Wi-Fi. This section might be called “DHCP Client List” or “Device List” or something similar.

   

4. You will find your LIFX light bulb listed here, along with its IP address and MAC address.

4. Find IP Address of LIFX Bulb Using Terminal

You can also use the Command Prompt on a Windows computer or Terminal on a Mac to find the IP address of your bulb. Here’s how:

1. Open Command Prompt on your Windows by pressing “Windows + R” or Terminal on your Mac by pressing “Ctrl + Alt + T”.
   

   

2. You need to know the MAC address of your bulb, which you can find using the methods listed above.
3. In Terminal, execute the following command:
   arp -a
   

   

4. You will see a list of all devices connected to your network, along with their IP and MAC addresses. Match the MAC address of your light bulb to find its IP address.
   

   

5. If you can’t locate the IP address, try another command. Enter the following command and press enter:
   sudo nmap -n -sn “192.168.1.*”
   

   

6. Most networks’ IP addresses start with 192.168.1. If yours is different, replace 192.168.1 with the first three octets of your IP address.
7. Look again for an IP address that matches the MAC address of your LIFX bulb.
