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.

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.PerformanceThe 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.ConstructionThe 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.

After looking around the big box home improvement store websites and finding all of the motion sensors for $75+, I went searching on amazon. 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.

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 Amazon 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.

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.
