Buyer's Handbook
Motion Security Lighting
Motion floodlights, porch fixtures with sensors, and battery and solar lights. What outdoor light really does for a home's security, why brighter often shows less, and how to light the way in without lighting up the neighborhood.
Reviewed October 2026. We re-check this guide quarterly.
Start here
The light that clicks on for the cat
The new floodlight over the garage is the brightest thing on the street. It snaps on for every cat, every passing car, and every gust that moves the maple. It also shines straight into the neighbor's bedroom, and from your kitchen window the yard behind it now looks darker than before.
Most outdoor lighting problems come down to three choices: how bright, which way it points, and what turns it on. All three are easy to get right, and getting them right usually means spending less, not more.
This handbook covers what light can and cannot do for a home's security, why glare works against you, how motion sensors decide, which power option fits each spot, and how to place lights so they help you, your neighbors, and your cameras see.
Before you buy
Six questions to answer after dark
Walk around the house one evening with these. The answers decide what to buy, where it goes, and how bright it needs to be.
Where would someone approach the house without being seen?
The back door, the side yard, the gap between the garage and the fence. The front porch is usually already lit. The dark sides are where light does the most good.
What power is already at each spot?
An existing outdoor fixture, an outdoor outlet, or nothing at all. That one answer narrows the choice to hardwired, plug-in, battery, or solar.
What should the light do for you?
Light your own way to the door with groceries, or call attention to movement in the yard. Many fixtures do both, staying dim all night and brightening on motion.
What is in the light's path?
A neighbor's window, the street, a sidewalk, branches that move in the wind, a dryer vent. Each one affects where the light can point and how often the sensor fires.
Does a camera watch the same spot?
Light placed for the camera, not in its eyes, can do more for night footage than a more expensive camera.
Who will do the ladder work and any wiring?
Replacing a fixture means working on household wiring at the top of a ladder. Decide up front whether that is a job for you or for an electrician, and choose the light to match.
How it works
Light helps people see, and that is most of it
Outdoor light does not lock anything or scare anyone off by itself. What it does is make it possible for you, your neighbors, and your cameras to see what is happening. Its security value depends on someone being in a position to look.
The evidence fits that picture. In a survey of 422 incarcerated burglars, 15.8% named outdoor lighting as an effective deterrent, well below outdoor cameras (50.3%) and indications of an alarm (53.3%).[1] In New York City, a randomized experiment that added temporary streetlights to public housing developments found at least a 36% drop in nighttime outdoor index crimes around those developments.[2]
For a single house, the most useful finding is the most specific one. A Chula Vista, California police study of burglarized homes rated outdoor lights on dusk-to-dawn timers as having relatively low effectiveness, and the prevention tips in the same report suggest motion detector lights.[3] A light that is always on becomes scenery. A light that changes when someone arrives is a signal.
What motion adds
A sudden change draws the eye, from inside the house and from next door. It also tells the person who triggered it that the spot is not as dark as they expected. That signal only works if the light does not fire so often that everyone learns to ignore it.
Light for your own footing
Much of the value is ordinary: finding the keyhole, seeing the step, carrying a sleeping child in from the car. A light that serves you every night is one you will keep working, which is also what makes it useful the one night it matters.
Light for the camera
Many cameras switch to their own infrared light at night and record in black and white unless there is light already there. Steady, well-aimed light on a doorway or path helps a security camera record faces and color after dark.
The order that follows
Decide where light is needed and who will be looking. Then get the brightness and aim right, choose what triggers it, and pick the power source that fits each spot. Locks come first in the house overall; lighting helps everyone see what the locks are holding back.
The distinction that matters most
Brighter is not the same as safer
The most common mistake in this category is buying the brightest light on the shelf and pointing it outward. Glare works against the people the light is meant to help.
The American Medical Association's report on LED community lighting notes that discomfort and disability glare can decrease visual acuity, decreasing safety. It recommends that all LED lighting be properly shielded to minimize glare, and encourages 3000K or lower for outdoor installations such as roadways.[4]
The glare trap
A bare light hides what stands behind it
Your eyes adjust to the brightest thing in view. A floodlight aimed toward the house, the street, or a window makes everything beyond it harder to see, from inside your kitchen and from your neighbor's porch. Light the ground and the doorway, not the eyes of whoever is looking.
How bright is enough
Lumens, not watts, and fewer than you think
Lumens measure brightness. A traditional 60-watt incandescent bulb gives about 800 lumens, and an LED can match it at about 9 watts.[5] Many motion floodlights are sold at 2,000 to 7,500 lumens or more. For a doorway or path, a shielded fixture near the low end, or one with adjustable brightness, is usually plenty.
Color temperature
Warm by default, neutral where a camera needs it
Many motion floodlights ship at 5000K, a bluish white. We use 3000K as our default for homes. The AMA's guidance is written for outdoor installations such as roadways, and the same glare reasoning applies at a front door. If a camera shares the light and its color footage looks poor, a neutral 4000K fixture, shielded and aimed down, is a reasonable trade. Many fixtures now let you switch.
The practical rule
Shielded, aimed down, kept on your side of the line
Choose fixtures that cover the bulb from above and the sides, tilt flood heads well below horizontal, and keep the beam inside your property. Your neighbors stay friendly, and friendly neighbors are the ones who look outside when your light comes on. Check whether your town or HOA has outdoor lighting rules.
What turns it on
Motion, dusk to dawn, or both
The trigger decides whether a light is a signal or scenery. Most fixtures sold for security combine a daylight sensor, so they stay off in the day, with one of the modes below.
Dusk to dawn
On all night at a steady level. Good for the door you use and the house number. Weak as a security signal, since nothing changes when someone arrives.
Use for: the main entry and the house number.
Motion only
Dark until something moves, then full brightness for a set time. The strongest signal, and less energy than a light left on. Dark the rest of the time, which suits side yards and back corners.
Use for: side yards, back doors, the driveway.
Dim, then bright
A low glow all night that jumps to full brightness on motion. You get light to walk by and a signal when someone arrives, with less glare toward the neighbors.
Use for: back doors and paths you use after dark.
How the sensor decides
Most motion lights use a passive infrared sensor, which reacts to moving warmth: a person, an animal, a car's engine. Most notice someone crossing their view sooner than someone walking straight at them, so aim the sensor across the path people take.
Sun-warmed branches, a dryer vent, and headlights sweeping past can all set it off. Some fixtures add a second sensing method or adjustable zones to cut down on those.
The three settings that matter
Sensitivity or range: set it to reach the path and the door, not the street. On-time: long enough to reach the door and get inside, and no longer. Daylight threshold: so it does not fire in daylight.
Look for these as dials or app settings on the fixture. A light you cannot adjust is a light you will end up unplugging.
Power
Four ways to power a light, four different trade-offs
The power source decides how bright the light can be, how reliably it works in winter, and how much installation it takes.
Hardwired
Replaces an existing outdoor fixture and uses its wiring. The brightest and most dependable option, with nothing to recharge. It goes dark in a power outage along with everything else on the circuit.
Plug-in
Plugs into an outdoor outlet, so there is no wiring to touch. Outdoor receptacles have required ground-fault protection under the National Electrical Code since 1973, and the CPSC advises testing GFCIs at least once a month.[6]
Battery
Mounts anywhere with a few screws and suits renters, sheds, and stairways. Usually dimmer, and the battery needs recharging or replacing on a schedule. Keeps working in a power outage.
Solar
A battery light with a small panel that recharges it. Free to run and keeps working in an outage, but it depends on direct sun. North walls, deep shade, snow on the panel, and short winter days all cut how long it runs.
When the power goes out
Hardwired and plug-in lights go dark with the grid. A solar or battery light on the back door keeps a path lit. For light inside the house during an outage, see our emergency lighting handbook.
Formats compared
Five kinds of light, each with a job
Price ranges are from Amazon listings in October 2026, and sales move them.
Porch fixture with a sensor
About $30 to $110
Looks like an ordinary wall light and replaces one. Many offer dusk-to-dawn, motion, or dim-then-bright modes. The best choice for doors you use every night.
Check: a shielded design that hides the bulb from the side, and the modes it offers.
Motion floodlight
About $20 to $40, hardwired
Adjustable heads on an eave or wall, for driveways, side yards, and back corners. Often very bright, so the aim and brightness settings matter more than the lumen number on the box.
Check: adjustable brightness and color, and heads that tilt well down.
Battery motion light
About $19 to $35
No wiring and no outlet. Good for renters, sheds, side gates, and stairs. Usually a few hundred to about 1,600 lumens, which is enough for a path.
Check: rechargeable or replaceable batteries, and how it charges.
Solar motion light
About $17 to $40, often in multipacks; larger units to about $100
For spots far from power with good sun. Cheap multipacks are fine for fences and paths; a larger unit with a separate panel suits a gate or shed.
Check: a panel on a cable that can be mounted in the sun, apart from the light.
Floodlight with a camera
See our camera handbook
A motion floodlight and a camera in one fixture. The light gives the camera color footage at night. The camera side brings subscriptions, accounts, and privacy choices with it.
Check: everything in the camera handbook, plus everything here.
Reading the spec sheet
Lighting boxes lead with lumens. These lines matter more.
Adjustable brightness and color
A dial or switch for brightness, and a choice of color temperature, let you fix glare after you install it instead of buying again.
Sensor range and angle
Given in feet and degrees. More is not better if it reaches the sidewalk. Look for adjustable range, or a sensor head that can be aimed separately from the lights.
Weather rating
Under IEC 60529, a first digit of 5 means dust-protected and 6 means dust-tight; a second digit of 5 means protected against water jets and 6 against powerful water jets.[7] For a light in the open, IP65 or better is a sensible floor.
A safety certification mark
For anything that connects to household wiring, look for the mark of a Nationally Recognized Testing Laboratory. OSHA explains that the mark shows the lab tested the product and found it meets one or more product safety standards, and it publishes the current list of recognized labs.[8]
Placement
Light the way in, not the sky
In the Chula Vista study, 65% of entry points were at the back or side of the house.[3] That is where a motion light earns its place.
Doors first
Every exterior door, then the dark sides
Light every door someone could use, including the back door and the side door to the garage. Then add motion lights along the side yards and at gates. The front of the house is usually the best-lit already.
From above, aimed down
Light faces and the ground, not the horizon
Mount high enough to be out of easy reach, and aim so the light falls on the doorway, the path, and the face of someone arriving. A beam that reaches the horizon is lighting the neighbors and the sky.
With a camera
Beside or behind the lens, never in front
Put the light where it falls on what the camera watches, not into its lens. A light inside the camera's view floods the image and turns the subject into a silhouette. Check a night clip after every change.
Test at night
Walk it, then look from inside and next door
Walk the path someone would take and note where the light fires. Then look out from your windows and, if you can, from your neighbor's side. Adjust the aim and range until it catches the path and spares the street.
What fails and why
The limits worth knowing before you rely on a light
A light that fires all night
Cats, cars, and branches set it off until nobody looks anymore. Lower the sensitivity, re-aim the sensor across the path instead of toward the street, and shorten the on-time.
A floodlight in the neighbor's window
It costs you goodwill and the neighbor's eyes on your yard. Tilt the head down, add a shield, or swap to a fixture that keeps the beam on your side.
A solar light that quits by midnight
December sun, a shaded panel, or a tired battery. Move the panel to full sun, clean it, and use wired power at the doors that matter most.
A dark spot nobody noticed
A failed sensor or a burned-out fixture looks like any other night. Walk the house after dark once a season, on the same day you test the GFCI outlets.
A light with nobody to see it
A motion light in a yard no one can see from inside or next door mostly lights the work. Pair it with a view from a window, a camera, or a neighbor who knows your routine.
A cord across the lawn
A plug-in light fed by an extension cord that never comes in. If a light needs permanent power where there is none, that is a job for new wiring or a battery or solar light.
Safety: wiring, ladders, batteries, and other people's eyes
Replacing an outdoor fixture means working on household wiring. NFPA's guidance is to have all electrical work done by a qualified electrician, and it notes that extension cords are intended for temporary use.[9] Plug outdoor lights only into ground-fault protected outlets, and test those outlets monthly as the CPSC advises.[6]
Most of this work happens on a ladder. OSHA's ladder guidance says to inspect the ladder first, keep three points of contact while climbing, set an extension ladder's base a quarter of its working length from the wall, never stand on the top three rungs of a straight or extension ladder, and keep metal ladders away from power lines.[10]
Battery and solar lights often use lithium-ion batteries. NFPA advises buying batteries listed by a nationally recognized testing laboratory, using the charging equipment supplied with the device, and taking a battery out of service if it shows an unusual odor, heat, popping sounds, swelling, or a change in color.[11]
Finally, never aim a bright light toward a street, a driveway, or a sidewalk where drivers and walkers will face it. The AMA's report notes that glare can decrease visual acuity and create a road hazard.[4]
