When gamers start Luigi's Mansion 2, they'll be given the Poltergust 5000 right away, but they will have to explore Gloomy Manor to recover its two attachments. Gamers will collect the Strobulb during the first mission, but they'll only gain access to the Dark-Light Device attachment when they start A-4: Visual Tricks.

The Dark-Light Device opens many doors in Luigi's Mansion 2, both literally and figuratively. This guide will tell players how this device works so they can take full advantage of it and unlock every secret in the game.

How to Use the Dark-Light Device

The Dark-Light Device has two main functions: it's able to detect hidden furniture or Boos and it can bring portraits to life.

  • To uncover objects or enemies with the Dark-Light Device, gamers must use it to scan an area where they believe there could be something hidden. If that is the case, it will slowly start to appear as the device charges up. If there is a hidden object, Spirit Balls will be released, and gamers must collect them. Once all the Spirit Balls have been vacuumed, the object will appear. If there is a hidden Boo, it will show itself upon being hit with dark light.

  • Gamers can activate portraits using the Dark-Light Device, and this can lead to great amounts of treasure, gems, keys, or even fire sources. To do this, simply shine dark light onto the portrait until it's activated.

Available Dark-Light Device Upgrades

The Poltergust 5000 can be upgraded a total of five times in Luigi's Mansion 2, and some of these improvements target the Dark-Light Device attachment on Luigi's ghost-hunting machine.

Two of the Poltergust 5000's upgrades will increase the duration of the Dark-Light Device in Luigi's Mansion 2. This means that players will be able to turn on the Dark-Light function on the Poltergust 5000 for longer without it overheating, which will result in it turning off. Here is how much treasure gamers will have to collect in order to improve the Dark-Light Device:
