Review: After looking around the big box home improvement store websites and finding all of the motion sensors for $75+, I went searching on desertcart. I found this J Lumi sensor and for the price decided to give it a shot. I bought three for less than half of what I could find them for elsewhere and to my surprise they work exactly as I hoped. The closets only had pull chain fixtures with no wall switch, so a ceiling mounted solution seemed like an easier fit. I'm from Texas in the US, and they work fine with my standard 120V, 60 Hz house wiring. I finished installing the third in my third bedroom closet yesterday. They were installed somewhat close to the door frame to avoid false tripping from inside the bedroom. All three have been working perfectly. I read some complaints about the wire size. I used 14/2 solid romex from the hardware store and didn't have any trouble. I would suspect 12/2 wouldn't be much trouble either. I did have to go into the attic to jumper the wiring from the existing fixture to the sensor and back. All connections were made from inside the living space, but I had to feed the wiring down to the sensor. Each sensor has 4 clearly marked terminals for line side and load side connections. It does not include a ground connection, though if you were installing in a similar situation to me, the existing electrical box would presumably have a ground wire to the existing fixture. I'm here to buy a couple more after the dog chewed one of the trim rings during installation, and to add one to another room. One slight critique to the design: I would prefer that it sat more flush to the ceilng. Instead of a dome shape where the fattest part would sit flush it is more like a full UFO shape where it flares out but then goes back in. It mounts well and isn't loose or janky looking, but I would prefer a cleaner look. For the price, or even for twice the price, I am fully satisfied with the product.
Review: I bought this motion sensor to set up in a laundry room, to keep the light on while someone is in the room. When I actually tried to install it I discovered a couple of design flaws that prevented it from being installed on the ceiling, as advertised. First, the hole punch-outs were the wires are supposed to connect are flush with the bottom of the device, and the device is supposed to be flush-mounted with the ceiling. No real way to get the wires into the device. I contacted JLUMI (execellent to deal with by the way) and was told that it is meant to be installed in a ceiling junction box. Problem is the mounting holes on the device do not line up with the mounting holes on a standard box. Even with a cross-bar on the junction box there is still no way to mount the device to the box. I contacted desertcart and was approved for a refund, but it has to ship to Kentucky, I am in Canada. Haven't checked yet but I expect shipping to the US will cost more than the device itself.

## Questions & Answers

**Q: what its the correct ceiling junction box ? i understand should be round and 4" , or should be another size or not round?**
A: If you are installing new, go with the 4" round ceiling box. If you are working w/ anything else, the holes might still line up and if not, you can get all sorts of adapters hardware at the local home center.

**Q: Does this pick up motion on the other side of walls? (e.g. motion not in the room)**
A: This is a PIR (passive infrared) motion sensor, which detects infra-red signal emitted from the object (a person or a pet) to trigger the load.  Therefore, the sensor can only detect motions of an infrared source in the same room, but not beyond walls.  

There are other type of motion sensor that uses Doppler radar signal to detect objects.  J.LUMI carries another model of motion sensor, SKU YCA2002, that is a radar enabled motion sensor and can detect objects behind thin door or thin plaster doors.  For that model, please search on Amazon using key words "J.LUMI YCA2002".

**Q: Are the screw holes set for mounting on a standard 4” hexagon box?**
A: To mount on a standard 4" hexagon box, please purchase one additional mounting accessory. Search on Amazon using terms "J.LUMI YCA1050A".  The listing page can be accessed via the following link (please copy and paste into your browser).

**Q: can you turn off the photocell?**
A: Not completely, but it can be turned down to just a few lux.

*by J***E on 28 November 2022*

Input Voltage on box has two options. 220-240VAC or 110-130VAC. Advertised as 85-265V AC. Didn't work out of the box. After careful inspection circuit board held in by a small dribble of hot glue. Quality is really poor. Drawing makes no sense.
