Firmware updating your LIFX lights

These instructions relate to App 4.0. Please make sure you have the latest version prior to following these instructions. Download for iOS or Android.


LIFX recommends you update your firmware whenever a new update becomes available. Firmware updates often include new features, bug fixes, improved security and performance enhancements.


Updating your Firmware

1. Click on the GEAR ICON in the bottom menu to open Account Settings
3. Lights that need a Firmware Update will be listed here. Please set through the in-app prompts

Leave the updater open. Do not power off any lights during the update.


4. If you have no updates available, it will say "All Up To Date" with no lights listed



Troubleshooting Firmware

Best practice:

1. Update one light at a time
2. Ensure your router is in close proximity to the lights
3. Turn off any lights at the switch that you do not wish to update


If your lights still don't update:

1. Turn the lights off at the switch
2. Wait for 5 seconds
3. Turn the light back on at the switch
4. Wait for 30 seconds
5. Run the updater again


If you continue to have issues:

1. Download the desktop LIFX Firmware Updater
2. Run the updater from your computer
3. If the updater is quickly showing 'All Bulbs Up To Date' without showing any progress, please force quit the app and reopen, and run the updater again


We also recommend:

1. Temporarily disabling wireless N on your Wi-Fi router
2. Effectively this is changing your 2.4Ghz network to be  802.11 b, g compatible, or 802.11g only
3. Once the update is complete, you will be able to re-enable the N settings o your router
