ENERLITES High Bay Ceiling Motion Sensor, Passive Infrared PIR Ceiling Sensor, 360° Field of View, 2800 Sq Ft Coverage, 120-277VAC, Neutral Wire Required, Commercial/Industrial Grade, MPC-50H, White

Works great, very easy to mount and wire, I'm operating a 20W LED light fixture with it Below are remarks about some previous reviews. "I found out after buying this item that you can reconfigure the 1/2" nipple to come off of the top of the device rather than the side." You can also remove the back box and mount it directly to the surface with 2 screws which I did. "Installed this sensor today, and I am disappointed! The light sensitivity adjustment does not work well, and the range is very short." Yours sounds like it is defective. Mine works great under approximately the same circumstances. I would have Amazon replace it. "The other misled is the time delay feature. The 15 second setting is only for testing. You can leave at this interval, but the next level would be 5 min to 30 min at 5 min increment. There is no setting between 15 second and 5 min." True, just 15 sec or , 5, 10, 15, 20, 25 or 30 minutes. But as long as you are moving in the area it stays on and when you stop moving it goes off at the delay that you have set it for. Right now I have left mine set at 15 seconds and while working in the area it stays on which is all that is required. If this doesn't end up meeting my requirements I will change it to 5 minutes or more.

Excellent product works great at 8'-10' comes with options for high up to 50' lens and low 10' or less. (didn't use high bay lens) Easy to install in open 1/2" electrical knockout. SB Ceiling mounted but would also work vertical just not as effective. They comes with all mounting hdw. Can easily set to various ambient light sensitivity and range as well as time on settings from 5 to 30 minutes at 5 minute intervals. Most important for me was being able to wire several to same lights to expand coverage. It wasn't clear in Amazon Description but it worked great for our big shop. with 2 in an area 50'X30' there is no dead spots. More could be added to cover areas around corners or if there are obstructions like high shelving. Also like the fact that they cant be tripped through thermal glass windows separating different areas. May also work in single pane windows however, I can not attest to that. Only issue I ran into was mounting directly to single bulb ceramic light fixture (Mounted to 1-1/2" oct metal box) the device interfered with mounting fixture I justed extended form mounting box a few inches.

I tested a couple of similar sensors and had to return them: the useable cone was not great. This one works great: as promised - truly 360 coverage. Good sensitivity. It catches movement in every corner of my garage and does it quickly - so the light comes instantly.

I found out after buying this item that you can reconfigure the 1/2" nipple to come off of the top of the device rather than the side. I was really happy. that increased the mounting flexibility tremendously. It's mounted on a box in the basement ceiling and works like a charm. The laundry room lights up when you walk in - no need to fumble the basket of clothes looking for the switch or pull chain. Installation was easy and the price is right.

Instructions were not all that great but it is pretty straightforward - so it doesn’t matter for someone who is handy. I had bought 3 sensors. They worked great but one of them stopped working. So my low rating is on the durability. It is a hassle to replace it and rewire it. I have reached out to the company and if their customer service makes up for the bad product, I will bump up the rating.

purchased 3 dozen for my warehouse project. Of all the 3 dozen or so purchased, 1 was defective, resulting in extra labor $$ to replace. We tried leaving the lights in the "on" position 24/7, but this doesn't seem to work well. Our surveillance cams keep picking up the lights turning on, and off, and on and off.. basically random lights in the warehouse turning on and off. We're not sure if this is a bug or what crawling or flying around but the sensitivity is a bit high. Not sure if the issues we encounter is due to price point or what but so far its barely up to the level of "commercial" use. If more than a few of them break over the time these are in use, it might be worth investing more to buy a higher quality product.

I have it in my wash room now for several mts works overtime .

Has been working flawlessly so far. I installed it about 6 months ago in the garage to control the lights. My wife loves it. Just walk in and the lights turn on. It seems to work much more reliable than the type integrated into switches. I was able to position it in the center of the garage so it senses motion from any direction. You walk into the garage, the lights come on, you pull the car in, the lights go on. I've never had them shut off on me while I was still in the garage. Also it drives a standard relay so it can drive any type of load. Mine drives LED lights perfectly.
