LOWENERGIE Motion sensor Indoor lighting PIR Occupancy Sensor switch 200w wall mounting auto on/off lights, presence detection

Overall - a fantastic product and would highly recommend it to anyone in need of a reliable way of ensuring lights are turned off when not in use. The motion sensor works well even in low light conditions, fitted in an an under stairs cloakroom. The installation process was straightforward, and I've been consistently impressed since putting it into use. Furthermore, when compared to other alternatives on the market, this model offers excellent value for money.It's worth noting that while it can be a snug fit, it is possible to install this switch within a 25mm back box. However, I'd suggest using a 35mm back box if possible. Unlike some other reviews I've seen, my package did not include the resistor for low draw loads, though this didn't pose any problems for my specific setup.A significant benefit I've discovered is its successful operation with a combined extractor fan and light fitting, which is something I know can be a concern with some other products.

Hidden dail for sensitivity.Fully qualified electrician here, I was caught out with this product as the sensitivity was very low and the only dial I could see was for time delay. Turns out you have to remove the label from the back and there is a hidden dial for sensitivity. Works well now that's sorted.

I thought I'd cover a few questions that I had before buying this ;1) It says wall mounting - can it be used on the ceiling - YES. it has been working just fine as a ceiling sensor even though its right next to the wall / door.2) Can it replace a pull cord - YES . as there is no neutral needed just swap it for what you have. Its even easier than a wall switch really in that your pull cord most likely has a large back box to take this.3) I cant see any screw holes on the faceplate - how does it attach ? - Easily - it also comes with a pair of screws, although I just reused the ones I had. the faceplate has a cover which just clips on to cover the screw heads4) There's a weird resistor in the instructions, what's that all about? - Ignore it. I assume this is to create a minimum amount of current draw for very low energy bulbs like LEDs, but I ignored it and its powering 3 x 9W LED downlights in a 10 x 10 bathroom no problem.The only downside is that the adjustments for the duration and light levels aren't easy to get at. I'd advise turning time to max and light to min before fitting it in place. Other than that its a great cheap unit.

Simple to fit and adjust

Works as described

Managed to fit into a standard wall light switch fitting. However I was concerned that the screw terminals are not recessed or shielded and could easily come into contact with the metal wall box. In my case I had to remove the unused screw tabs in the wall box and insulate the screw terminals of the product.However product works very well in our spare room where the light was constantly being left on.

Did not work and screws don’t match standard box

Item works well when installed and looks neat, the faceplate fitting well to the main part. It also doesnt require a neutral, so they can be connected in the backbox if you have them. As pointed out this wont fit a 16mm back box but it's not overly deep. However a few niggles which let this down. Firstly the screws are an odd size and don't fit a standard back box, luckily I kept them from the switch I was replacing. Second is that where connections are made they use + screws which aren't great and seem to have sheared. Overall not bad value for the price
