Lights out time in jails and prisons usually falls between 9:00 PM and 11:00 PM, with the exact hour set by the facility, its security level, and the agency that runs it. A federal prison camp may dim the main lights right after a 9:00 PM standing count, while a county jail holding pretrial detainees might keep common-area lights on until 10:30 or 11:00 PM. No single federal law sets a universal bedtime for correctional facilities, so schedules vary more than most people expect.
What Lights Out Actually Means
The phrase sounds like everything goes dark. It almost never does. When staff call lights out, the bright overhead fluorescents in cell blocks and dormitories switch off or dim significantly. Low-level security lighting stays on all night in virtually every facility in the United States, because officers need to see into cells during overnight rounds and counts.
How bright that residual lighting is varies. Some facilities use soft nightlights mounted near the floor. Others leave corridor lights on with enough glow leaking into cells to read by. There are no federal or state maximum lighting-level requirements for correctional facilities during sleep hours, and courts have generally left those decisions to administrators so long as the lighting serves a security purpose.
Timing by Facility Type
The biggest factor in when lights go out is what kind of facility you are in. A minimum-security federal camp, a state penitentiary, and a county jail can run very different schedules from one another.
Federal Prisons
The Federal Bureau of Prisons operates facilities at every security level, and each institution publishes its own inmate handbook with a daily schedule. At minimum-security camps, main lights commonly go off after the 9:00 PM standing count. Phone access in federal facilities typically shuts down by 11:30 PM and showers close around 10:30 PM, which gives a rough window for when the BOP expects inmates to be settling in for the night. Wake-up is generally around 6:00 AM.
State Prisons
State systems set their own schedules and the range is wide. Some state facilities push lights out as early as 8:30 or 9:00 PM, particularly in higher-security housing units where tighter control over movement is the priority. Medium- and minimum-security state facilities often land closer to 10:00 or 10:30 PM. The variable that matters most is the security classification of the housing unit, not the institution as a whole. An inmate in administrative segregation at the same prison may have a completely different schedule than someone in general population.
County and City Jails
Local jails tend to run later than prisons. Their populations include pretrial detainees who have not been convicted, and shorter stays make rigid scheduling harder to enforce. Lights out at 10:00 to 11:00 PM is common. Some jails never fully turn off the overhead lights and simply rely on dimming, which blurs the line between lights out and quiet hours. Jail handbooks often specify a sleep period during which bedding use is permitted and noise must be kept down, even if the lights never fully go off.
The Evening Routine Before Lights Out
The last few hours of the day follow a predictable sequence in most facilities. Missing a step can mean going without something until morning.
- Dinner is typically served between 4:00 PM and 6:00 PM. In many facilities, dinner is the earliest major meal, which catches newcomers off guard.
- After dinner, inmates get a final window for recreation, phone calls, email access, showers, and commissary purchases where available. This window usually runs until an hour or so before lights out.
- Evening pill call happens during that same window. Missing it means waiting until the morning dose.
- A standing count occurs shortly before lights out. Inmates must be visible at their assigned bunk or cell door, and no one moves until the count clears. If the count comes back wrong, everyone stays put while officers recount, and the schedule slides.
- Once the count clears, inmates in celled housing are locked in. Dormitory-style housing may simply dim the lights and begin enforcing quiet hours.
The standing count is the hard boundary. Once it starts, the evening is effectively over regardless of what the clock says.
Rules After Lights Out
Once the lights go down, the expectation is simple. Be in your bunk, stay quiet, and don’t move around. The specifics vary by facility, but some patterns hold nearly everywhere.
Quiet activities like reading are usually permitted, and many commissary lists include small battery-operated reading lights and headphones for that reason. Facilities that allow personal televisions or tablets typically require headphones after lights out. Writing letters, drawing, and similar silent activities are generally tolerated as long as they do not disturb other inmates or interfere with officers’ ability to see into the cell.
Movement outside your assigned bunk area is heavily restricted. Leaving your cell or bunk is typically limited to genuine emergencies and authorized medical needs. Using the toilet in a celled unit is obviously permitted; walking around the housing unit is not. Inmates who need to alert staff to a medical emergency can call out to the officer on duty or use an intercom system where one exists.
The noise rule generates the most friction. Talking, playing music without headphones, or making any sustained noise after lights out will draw a warning and then a disciplinary report. Repeated violations can result in loss of commissary privileges or placement in more restrictive housing.
Overnight Counts and Staying Visible
Counts do not stop when the lights go out. Most facilities conduct at least two additional counts overnight, often around midnight and again between 3:00 and 5:00 AM. These are typically census counts rather than standing counts, meaning officers walk through and visually confirm each inmate is in their bunk rather than requiring everyone to stand.
This is why security lighting stays on and why many facilities have a strict rule against covering your face or head while sleeping. Officers conducting a count need to confirm that the shape in the bunk is a living person, not a pile of blankets. Facility handbooks commonly state that inmates must sleep with their heads uncovered and visible to staff at all times. Getting caught with a blanket over your head during a count is a common way to pick up a minor disciplinary charge.
Constant Illumination and Your Rights
The gap between dimmed lights and lights always on matters legally. In general population, lights get turned down at a predictable hour and the arrangement works for most people. In segregation units and some high-security housing, some facilities keep bright lights on around the clock. That practice has been challenged in court with mixed results.
In LeMaire v. Maass (1990), a federal district court in Oregon ruled that 24-hour lighting in a disciplinary segregation unit was unconstitutional, finding no legitimate security justification for forcing inmates to endure constant illumination. The Ninth Circuit reached a similar conclusion in Keenan v. Hall (1996), emphasizing the psychological harm of disrupted sleep patterns.1AMA Journal of Ethics. Sleep Is a Human Right, and Its Deprivation Is Torture
Other courts have gone the other way. In Huertas v. Secretary, Department of Corrections (2013), the Third Circuit found that 24-hour lighting in a corrections unit did not rise to the level of an Eighth Amendment violation, noting that not every inadequacy in prison conditions amounts to a constitutional violation.1AMA Journal of Ethics. Sleep Is a Human Right, and Its Deprivation Is Torture Constant illumination is not automatically unconstitutional. Courts tend to ask whether the facility has a legitimate security reason for the lighting and whether the inmate suffered demonstrable harm. These claims are difficult to win, and the law remains inconsistent across federal circuits.
Reaching Someone Inside After Hours
If you are trying to contact someone in custody, the lights-out schedule shapes when you can make contact. Phone systems in federal facilities typically go offline by 11:30 PM and do not reopen until 6:00 AM. Email and tablet messaging systems follow similar windows. The last hour before lights out is often the most congested, since every inmate on the unit is trying to make a final call of the day. Earlier evening calls, right after dinner, tend to have shorter wait times.
For someone entering a facility for the first time, the adjustment to the schedule is one of the hardest parts of the first week. Dinner at 4:30 PM and lights out at 9:00 PM leaves a long, dark stretch with nothing to do if you did not buy a reading light and headphones from commissary. Those two items, along with a decent pair of earplugs, make the overnight hours significantly more bearable.
