J.LUMI YCA1050 PIR Motion Sensor Light Switch, 85-265V AC 2000W, Ceiling Mount Motion Sensor Ceiling Motion Sensor Switch, PIR Occupancy Sensor, Slim Profile, White - desertcart.com

Review: I was skeptical for the price, but very happy with the results - 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: Works as advertised; some Doubt about reliability - I like this device. It works well, works perfectly in my situation. Installation It was relatively simple to install. I’ve got experience installing electrical devices - outlets, switches, light fixtures. Installing this involves *about* the same level of complexity. I say “about”, because it’s a little more complicated: you’ve got to have access to the line, and that’s most likely when you’re installing new fixtures or when you’re working in a garage with an unfinished ceiling. The biggest gripe I have is with the way the lines connect into the device. Most of us are accustomed to the familiar reliable connections on a 110/120 3-way receptical. You can simply insert stripped lines into the back and they auto-clamp, or you can use a #2 Philips screwdriver to clamp the wires. This device does not match that experience. The low-profile design of the device is part of the problem. the lines enter into the underside of the device (ceiling side) and then immediately turn 90 degrees. Immediately means, within 1/4 inch. There is a clamping attachment for neutral and hot for the line in, and for the load. There is no mutual ground. Because of the small space, the clamping screws are tiny. I needed a special small (tiny!) philips screwdriver to turn the screws. The _feeling_ was a problem too; it took me a few tries to feel certain that the lines were attached properly. Again, this is because of the low profile. And I had to rig a neutral junction with a wire nut (not provided) in very little space. Because of the novel attachment setup, I wonder if this device does passes electrical code in most states. I’m no expert but the connections are not of the same caliber as most devices I have installed in my home. The code is there for a reason - consistency leads to long term safety even in unusual circumstances. I wonder how reliable these connections will be ina tremor, or even with normal house shifts. Performance The unit works great. Once installed it works like a charm. Now when I move the car into the garage, the two LED light bars turn on automatically. This makes it much safer in the evening, as I get out of the car. It does just what I wanted it to do. It’s easy to adjust, although again you need a tiny screwdriver to make those adjustments. The instructions are clear on how it works and what the 2 controls do for you. Construction The device appears to be constructed well. The circuit board is well anchored and the case is reasonably durable. It’s just too small. There’s a warranty on the device - 1 year! And that’s amazing. I don’t expect to have to replace hard-wired electrical devices after a year. If I DO have to replace it, I’ll use a different device. it will be a challenge, though, because I’ve cut the lines short enough to accommodate the “low profile” of THIS device. Any device with a deeper profile will need longer lines.

## 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.

### ⭐⭐⭐⭐⭐ Great value and easy to install
*by B***S on April 19, 2020*

Fairly easy to install, hooked up wires backwards and it didn't work but was fine after switching them. Instructions are pretty confusing for the wiring with the terminology used in them. Has been working great for about 2 months now. Would recommend. Guess I shouldn't have reviewed this item! The very next day this stopped working. Fiddled with the settings know and it started working again. A week later the light won't shut off at all. Lasted about 2 months working perfectly and then died. Will need to take it down and see if I can figure out what happened. Bought 2 to start with and may have to put the other up. Will keep you updated.
