How to unlock the Edison achievement in Metro: Last Light Redux - Definitive Guide
Load up the chapter: Facility.
After speaking with Pavel, crawl through the vent. There is a lamp at the end of the short corridor of the room you drop into, a lamp round the corner on the metal stairs and a further lamp next to a soldier just past the second lamp. Turn all these off (the soldier won't even notice), and then reaload the checkpoint. Rinse and repeat as needed - took me less than 5 minutes.
In order to turn off a light without breaking it, you will need to press the button when facing a light source and the button prompt appears. This allows you to unscrew/turn off the light bulb silently without breaking it. There are plenty of light sources scattered throughout the entirety of the game, so this achievement will come naturally during either of your two playthroughs. Once you’ve safely turned off a total of forty lights, the achievement is yours.

This will come naturally while playing. Make a habit of turning off every single light you can and not shooting any but they must also be 40 different lights, you can't turn off the same one 40 times.
