DON'T LET HIM IN Flashlight Guide: Batteries, Charge, and Stealth

The flashlight in DON'T LET HIM IN looks like a simple starter tool, but it's really a two-part system: the light you carry into every run, and the batteries that keep it burning. The light does nothing on its own — until you find a battery and equip it, the flashlight is dead weight. Once the entity cuts the power, dead weight is exactly what you can't afford.

The whole system comes down to five habits:

• Find a battery pickup and equip it to power the flashlight.
• Watch the battery meter just above your hotbar.
• When the light dies, grab the next battery and equip it; the beam coming back on confirms the swap.
• Switch the flashlight off when he might be close — he can see it.
• Grab spare batteries whenever you pass one. With no working light you can't see, and in the dark you're as good as dead.

How the flashlight works

You carry the flashlight into a run, but it never works by itself: it needs a separate flashlight battery. Batteries exist as pickups in and around the house, and the game tells you exactly what to do with them — the on-screen prompt reads "Equip a battery to use it." One player caught in the dark summed up the trap: "I need like a flashlight or something, bro. I mean, a flashlight battery. I have a flashlight, but not A BATTERY."

So the power loop is: spot a battery pickup, take it, equip it, and the light works. Equipped batteries are consumables — each one runs down as you use the light, and when it's spent you're back to hunting pickups.

Watch the charge meter

Your flashlight battery level is displayed just above the hotbar, so you can check it at a glance without opening any menu. Charge runs down while the light is on, and drain is a felt mechanic, not a silent bar: in group play teammates warn each other that a flashlight might be "lowbat," and players announce being lowbat themselves — the players' shorthand for a battery running out.

The game gives you a bar, not a countdown — there's no stated drain rate or minutes-per-battery figure — so treat the meter as your only reliable warning and swap early instead of letting it hit zero somewhere dangerous.

Swapping a dead battery

When the light dies mid-run, the fix is a fresh battery, not a repair. The recorded swap follows four steps:

1. Recognize the dead battery: the light fails, and the player calls it — "Yo, my battery does not work."
2. Grab the next battery pickup: "Okay, grab this one."
3. Equip it, counting it in — "two and then three."
4. Confirm success: the beam comes back on. "IT TURNED ON."

That last moment is your recognizable completion signal. The light snapping back on tells you the new battery is in and working — if you don't see it, the swap didn't take.

Turn it off when he's close

The flashlight has a stealth cost, and the in-game tutorial states it plainly: "Turn off your flashlight. He can see it." Experienced groups apply the same rule unprompted, opening a night by telling each other to turn their flashlights off first. The light that lets you see also gives away where you are, so switching it off is routine play, not a panic move — kill the beam whenever he might be coming in, and flip it back on only when you actually need to see.

No batteries, no survival

Treat batteries as the resource your run depends on. Dropping into a pitch-black house, one player went for spares before anything else: "let me grab as much batteries as possible cuz like, bro, I don't even... you literally can't see nothing, bro. If you don't have any batteries, you just die." Two things follow: visibility without a working light is near zero, and running out of batteries is treated in play as effectively a death sentence. Collect spare pickups whenever the opportunity appears — spares are the difference between managing a blackout and being stuck in one.

How much light does it give?

Keep expectations modest. In one recorded run, a player holding the lit flashlight during a blackout still couldn't make out the house: "Yo, what type of flashlight is this, bro? Yo, I can't see NOTHING WITH THIS FLASHLIGHT," and later, "I have to literally look at the walls cuz like I literally can't see nothing." Those moments played out while the entity had cut the power, so the flashlight's own beam can't be separated from the overall darkness — there's no fixed beam rating to quote. Expect a modest personal light and judge it for yourself in your first runs.

Flashlight or floodlight?

Don't conflate the handheld flashlight with the house's floodlights. The tutorial also has you "turn on a flood light" when the entity is at the door or window, but that's a separate fixed fixture with its own system — not a feature of the light in your hand. If you're working through the scare-off routine, that step belongs to DON'T LET HIM IN floodlights.

That's the entire loop: batteries in, meter watched, dead ones swapped, light off when he's near. For the pickups themselves, see DON'T LET HIM IN battery; for the rest of what you can carry, see DON'T LET HIM IN items; and for how a whole night fits together, DON'T LET HIM IN walkthrough puts the flashlight into the context of a full run.
