Turning the light off is really easy! 

On the Brid App Home page you can find a toggle button on the top right hand side, which allows you to control your Brid's light.

If the toggle is blue it's on, if it's black it's in off mode.

If the button doesn't work please read this freshdesk  article: How to upgrade Brid's firmware

By turning Brid's light off you reduce its air cleaning efficacy.

Brid is programmed to automatically adjust the light accordingly to the mode you choose.

Your Brid will turn on automatically when you change modes.
