Specifications are the manufacturer or retailer published figures, compiled by hand. We have not measured them, and where a figure is not published we write "Not published" rather than guess.
01
Four rooms, and everywhere else
Motion sensing has an unusually sharp boundary. In the right room it is one of the best things you can do to a light. In the wrong room it is the reason people take sensors back out of walls.
The dividing line is whether anyone sits still. A sensor watches for movement; a person reading, typing or watching television produces very little of it, so the light eventually decides the room is empty and switches off on someone who is plainly there.
| Space | Sensor? | Why |
|---|---|---|
| Closet or wardrobe | Yes | Seconds of use, hands full, nobody sits |
| Pantry | Yes | Same, and the door often blocks a switch |
| Laundry or utility | Yes | In and out, hands full |
| Garage or basement stairs | Yes | Safety, and you arrive carrying things |
| Hallway | Often | Brief occupancy; see the hallway page |
| Living room | No | People sit still. It will switch off on them. |
| Bedroom | No | Same, plus nobody wants a light triggering at 3am |
| Home office | No | Typing is not enough motion for many sensors |
A sensor with fine-motion detection, like the Lutron Maestro sensor, pushes that boundary outward - it is specified to pick up small movements such as typing or reading. It does not eliminate the problem, and we would still not put one in a living room.
02
Occupancy or vacancy - the setting that matters
Nearly every sensor switch offers both modes and most people never change the default. They do quite different things.
Occupancy mode switches on when it sees you and off when you leave. Convenient, and it will happily light a room at two in the afternoon that had plenty of daylight.
Vacancy mode makes you switch on manually and only automates the off. It is less magical and it is the mode that actually saves energy, because a light never comes on in a room that did not need it. For a pantry or a laundry room where you would flip the switch anyway, vacancy is the better default.
And the wattage rating is a non-issue at domestic scale - a 250W sensor switch is carrying maybe 50W of LED. What matters is that the model is rated for LED loads, exactly as with a dimmer. See dimmer and bulb compatibility.
03
The renter routes
A sensor switch replaces a wall switch, which is electrical work and off the table in most rentals. Three alternatives, none of which touch the wiring:
- A smart plug on a schedule. Not motion at all, and for a hall or an entry used at predictable times it is more reliable than motion anyway - the light is on before you arrive rather than after you have already walked into a dark room. A Matter smart plug handles it.
- A smart bulb on a schedule where the fitting is a ceiling light with no lamp to plug in - a hub-free bulb does the same job in the socket.
- A battery motion light in a closet or cupboard with no power at all. This is the one place battery lighting is genuinely the right answer, and it is covered in pantry, closet and shelf lighting.
A second smart plug on a schedule is usually a better buy than a motion sensor for a renter, because a schedule cannot fail to see you.
The picks
Every pick in full
01
Lights that should switch themselves off
Lutron Maestro Motion Sensor Switch
#ad No live price right now, so we show none. How we earn
250W on a sensor with fine-motion detection, so it does not switch off on someone sitting still reading - which is the failure that makes people rip motion sensors out.
| Lumens | n/a - controls a circuit, does not light |
|---|---|
| Color temperature | n/a |
| CRI | n/a |
| Power source | Replaces a wall switch. Electrical work. |
| Dimmable | No - switching only on this model |
| Renter-safe method | NOT renter-safe. Replacing a switch is an electrical alteration needing permission. |
What it gets right
- Fine-motion sensing, so it does not shut off on someone reading or typing
- No neutral wire required, 250W, single-pole
- Occupancy or vacancy mode - vacancy is the one that actually saves energy
What it costs you
- Electrical work, so not an option in a rental
- A sensor in a living room is usually the wrong tool - this belongs in utility spaces
- Switching only; dimming needs a different model

02
Making a lamp smart without changing its bulb
TP-Link Kasa Matter Smart Plug EP25
#ad No live price right now, so we show none. How we earn
Matter native with no hub and built-in energy monitoring, at roughly the price of one smart bulb - and it works with whatever high-CRI bulb you already chose.
| Lumens | n/a - controls a lamp, does not light |
|---|---|
| Color temperature | n/a |
| CRI | n/a |
| Power source | Plugs in between the lamp and the outlet |
| Dimmable | No - switches only. Dimming stays with the bulb. |
| Renter-safe method | Plugs in. No wiring, no switch change, nothing fixed. |
What it gets right
- Matter native, so it answers to Alexa, Google Home, Apple Home and SmartThings with no hub
- Energy monitoring built in, which is how you check a running-cost figure yourself
- Works with any bulb, so light quality stays your decision
What it costs you
- Switches rather than dims - a dimmable lamp still needs a dimmable bulb
- Occupies the outlet, which matters on a crowded power strip
- Energy monitoring on budget plugs is approximate, not metering-grade

03
The cheapest way into hub-free smart lighting
WiZ WiZ Connected Color A19 Smart Bulb
#ad No live price right now, so we show none. How we earn
Wi-Fi and Matter with no bridge to buy, at roughly the price of two ordinary bulbs - the sensible default when you are lighting a rental you may leave next year.
| Lumens | Not published |
|---|---|
| Color temperature | Tunable white plus color |
| CRI | Not published |
| Power source | Screws into a standard E26 socket |
| Dimmable | Yes - in app |
| Renter-safe method | A bulb swap on your own Wi-Fi. No hub, no wiring, no switch change. |
What it gets right
- No bridge, no hub, nothing extra plugged into the router
- Matter support, so it is not locked to one ecosystem
- Cheap enough to do a whole apartment rather than one room
What it costs you
- Wi-Fi bulbs each take an address on your network
- CRI and lumen figures are not published per SKU
- Anyone flipping the wall switch takes the bulb offline

04
The same job on the newer app
TP-Link Tapo P115 Smart Plug
#ad No live price right now, so we show none. How we earn
The EP25's sibling from the same manufacturer with the same energy monitoring and Matter support, on TP-Link's newer app with cleaner energy dashboards.
| Lumens | n/a - controls a lamp, does not light |
|---|---|
| Color temperature | n/a |
| CRI | n/a |
| Power source | Plugs in between the lamp and the outlet |
| Dimmable | No - switches only |
| Renter-safe method | Plugs in. No wiring, nothing fixed, comes with you. |
What it gets right
- Energy monitoring with a clearer dashboard than the older app
- Matter support, so it is not tied to one ecosystem
- Compact enough not to block the second socket on most outlets
What it costs you
- Another vendor app and account if you already use a different one
- Switching only - no dimming
- Consumption figures on budget plugs are within a few percent, not exact

FAQ
Questions people actually ask
+Where should you use motion sensor lights indoors?
Places you enter with your hands full and leave without thinking: closets, pantries, garages, laundry rooms, basements and stairwells. Anywhere people sit still - living rooms, bedrooms, home offices - a sensor eventually switches the light off on someone reading, which is why they get removed.
+What is the difference between occupancy and vacancy mode?
Occupancy mode turns the light on automatically when it detects you and off when you leave. Vacancy mode requires you to switch on manually and only handles the off. Vacancy is the one that actually saves energy, because it never turns a light on in a room that had enough daylight.
+Do motion sensor switches work with LED bulbs?
Modern ones do, and the wattage rating is rarely a constraint - a 250W switch is carrying maybe 50W of LED. Check that the model is rated for LED loads rather than only incandescent, the same way you would with a dimmer.
+Can renters use motion sensor lighting?
Not by replacing a switch, which is electrical work. The renter routes are a smart plug or smart bulb running on a schedule, or a battery motion light in a closet where no wiring exists at all.
