For Lumen, you must be in Brooklyn during the nighttime, preferably after 9 pm.

Secret Lumen Hunter Mask guide in The Division 2
To get the secret Lumen Mask, go to Brooklyn just after 9 pm. Specifically, head to the main bridge located in front of the primary settlement.

Here, locate a small alley as shown in the image below, and then approach a garage entrance.

If you go there at night, an interaction will appear on the door, allowing you to open the garage. Inside, interact with the switch on the wall to start the puzzle.

You will see a Hunter symbol with several arrows pointing at it. Your task is to follow the Hunter symbols scattered throughout the different corners of the Brooklyn open world, and ultimately end up in a location where the Hunter spawns.
After discovering one symbol, you will find the next symbol nearby.

The final location is at the very right side of the Brooklyn map, near Bridge Street. You will find the Hunter symbol with numerous arrows pointing at it. Upon approaching the location, the Hunter will then spawn.

Defeat the Hunter to get the Lumen Mask as a drop.
