Fallout 4: Vault-Tec – How to Power Your Vault Rooms & Lights

Confused by the new lights in the Vault-Tec Workshop template? The underground settlement of Vault 88 changes the system with objects that require power, but can’t be connected to a generator directly. Instead, you’ll need to use conduits and generators to connect power.

Where does Fallout 4 explain any of this? It doesn’t. Learn all about providing power to Vault interiors with our quick guide and overview below.

Vault-Tec – How to Power Your Vault Rooms & Lights

Power is a tricky thing in Vault 88. Many of the lights that snap onto Vault structure ceilings and walls can’t be connected to power with wires. There’s no connector — instead, power needs to be supplied to the rooms themselves. Sounds complicated? Don’t worry, it isn’t too tough.

There are two important new additions to the Workshop you’ll need to be aware of:

• Vault Power Conduit
• Vault-Tec Reactor / Super-Reactor

The Vault-Tec Reactor snaps directly into the floor in vault structures, and directly supplies power to any connected rooms. That’s all well and good, but what about rooms that aren’t connected?

There’s where the Vault Power Conduit comes in. This additional device is found here in the Workshop menu:

• Power -> Connectors & Switches -> Vault Power Conduit

Vault Power Conduits snap to walls and transmit power to anything in a three to four square radius. You’ll need to place plenty of these devices around an atrium to power all your lights — they can be placed on the outer walls of Vault structures, too.

Vault Power Conduits always snap to the center of walls. If you’re having problems using the conduit, there is another easy option; the Power Radiator Conduit. Find it here in the Workshop menu:

• Power -> Conduit -> Conduit – Power Radiator

This all-purpose conduit snaps to Vault rooftops. It can be easily hidden on top of structures, and the handy bulb connected to the conduit will light up if the device is working.

Using Power Radiator Conduits and Vault Power Conduits, along with the massive energy output from Vault-Tec Reactors, you should have no problem providing power to Vault 88.
