Finishing is not very good. However cable connecters are of very good quality. Product is quite bulky. I had a LED light in my ceiling before fitting perfectly. But to install it i had to do some retrofiting just to accommodate its bulky body. Still hangs out a little. Other than that working wise works great as mentioned in description. Also can be installed to a heavier load of about 800W. And just so that there is no confusion among new buyers, its NOT a light its simply just a switch that is triggered by motion. Review: I am Using This Product For Last 5 Year and its working Perfectly fine. ## Features - 360-Degree Detection Range: The BT31FC Motion Sensor Switch has a 360-degree detection range, providing full coverage and ensuring that no motion goes undetected. - Adjustable Time Delay: The time delay for the motion sensor switch is adjustable, with options ranging from 10 seconds to 7 minutes, allowing for flexibility in customization. - Suitable for a Variety of Loads: The motion sensor switch is compatible with different types of loads, including incandescent lamps, LED lights, CFLs, and fans, with a maximum load capacity of 1200 watts. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MTD4K9A | | ASIN | B01MTD4K9A | | Batteries Included? | No | | Batteries Required? | No | | Color | White | | Customer Reviews | 4.0 4.0 out of 5 stars (264) | | Customer reviews | 4.0 4.0 out of 5 stars (264) | | Date First Available | 7 January 2017 | | Date First Available | 7 January 2017 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 120 g | | Item model number | BT-61C1 | | Item model number | BT-61C1 | | Manufacturer | Blackt Electrotech | | Manufacturer | Blackt Electrotech | | Number Of Pieces | 1 | | Package Dimensions | 11.2 x 10 x 8.2 cm; 120 g | | Package Dimensions | 11.2 x 10 x 8.2 cm; 120 g | | Part number | BT-41FC | | Plug Profile | Ceiling Mount | | Power source type | Battery Powered | | Size | 3 x 2 | | Wattage | 300 watts | | tech_spec_battery_description_toys | Battery not included | ## Product Details - **Brand:** Blackt Electrotech - **Colour:** White - **Item weight:** 120 Grams - **Maximum range:** 6 Meters - **Power source:** Battery Powered ## Images ![Blackt Electrotech BT31FC Fall/Recessed Ceiling Mounted Plastic Energy Saving PIR Motion Sensor Switch with Light Sensor (White) - Image 1](https://m.media-amazon.com/images/I/61FBr11Z-OL.jpg) ![Blackt Electrotech BT31FC Fall/Recessed Ceiling Mounted Plastic Energy Saving PIR Motion Sensor Switch with Light Sensor (White) - Image 2](https://m.media-amazon.com/images/I/71cuYavWAKL.jpg) ![Blackt Electrotech BT31FC Fall/Recessed Ceiling Mounted Plastic Energy Saving PIR Motion Sensor Switch with Light Sensor (White) - Image 3](https://m.media-amazon.com/images/I/61jX06wIFDL.jpg) ![Blackt Electrotech BT31FC Fall/Recessed Ceiling Mounted Plastic Energy Saving PIR Motion Sensor Switch with Light Sensor (White) - Image 4](https://m.media-amazon.com/images/I/61pcI-bJIIL.jpg) ![Blackt Electrotech BT31FC Fall/Recessed Ceiling Mounted Plastic Energy Saving PIR Motion Sensor Switch with Light Sensor (White) - Image 5](https://m.media-amazon.com/images/I/41goV2uaYFL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***. on 28 February 2026* ### ⭐⭐⭐⭐ Review *by S***T on 11 June 2020* It is over all a good product.
