Review: quality product ! - best ! gifted to electical contractor ! he was also happy ! Review: Works perfectly fine, easy to assemble with little knowledge of electrical ... - Works perfectly fine, easy to assemble with little knowledge of electrical appliance. I connected this to my two gate lamp and now no longer need to switch gate lamp on and off every day. Even if i am away from home and traveling. The device looks nice even if it is hung outside on single screw. Two suggestions: 1. Keep the wire little longer, considering the fact that you can not keep sensor just beside the lights other wise sensor will never work and so for a very short distance i had to connect small 20 cm wire to extend it. 2. Both the sensor are tuned for different lux and so every evening first light starts and after few min the second one. This difference could be avoided. though it doesn't create much problem. Its working as expected since last week. Upade after more than a year-long One is still working and other one stopped due to rain water. I shifted the connection under she'd to protect. In short, it's not water proof ## Features - 🌞 [Automatic Light Control]: Utilizes a light sensor to automatically turn loads on/off based on ambient light conditions, perfect for night-time operations. - 💡 [Versatile Applications]: Ideal for controlling garden lights, streetlights, incandescent lamps, and LED lamps, providing energy-efficient lighting solutions. - 🌧️ [Waterproof Design]: Built to withstand outdoor elements, making it suitable for both indoor and outdoor use in various environments. - 🛠️ [Easy Installation]: Crafted from high-quality materials for durability and simplicity, ensuring quick setup and reliable operation. - ⚡ [High Performance]: Operates on AC 220-250V, supports a rated current of 6A, and a switching frequency of 50/60Hz for consistent performance. - 🛡️ [Warranty]: Backed by an 12-month warranty against manufacturing defects, ensuring peace of mind and lasting reliability need to return and replace. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076SQG56H | | Best Sellers Rank | #59,013 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #617 in Electrical Wall Switches | | Brand | Blackt Electrotech | | Brand Name | Blackt Electrotech | | Circuit Type | 2-way | | Color | white | | Compatible Devices | Incandescent lamps, LED lamps, Garden lights, Street lights | | Connectivity Protocol | Wi-Fi | | Connector Type | Clamp | | Connector type | Clamp | | Contact Material | Bronze | | Contact Type | Normally Closed | | Contact type | Normally Closed | | Control Method | Sensor | | Control Type | automatic | | Controller Type | Push Button | | Current Rating | 6 Amps | | Current rating | 6 Amps | | Customer Reviews | 4.2 out of 5 stars 2,235 Reviews | | Item Dimensions | 8 x 7 x 12 centimeters | | Item Weight | 0.01 Ounces | | Manufacturer | Blackt Electrotech | | Material Type | Brass Plastic | | Model | BT31P2-2 | | Mounting Type | Handlebar Mount | | Number of Items | 1 | | Number of Positions | 2 | | Operating Voltage | 250 Volts | | Operating voltage | 250 Volts | | Operation Mode | ON-OFF | | Operation mode | ON-OFF | | Part Number | BT31P2-2 | | Smart Home Compatibility | Not Smart Home Compatible | | Specification Met | IEC 60669-2-1:2002 | | Switch Type | LDR Switch | | Terminal | Solder | | Unit Count | 1.00 Count | ## Product Details - **Connector type:** Clamp - **Contact type:** Normally Closed - **Current rating:** 6 Amps - **Operating voltage:** 250 Volts - **Operation mode:** ON-OFF ## Images ![Waterproof 230Volt Auto Day/Night on and Off Photocell, Light Sensor LDR Switch for Lighting 2 Pieces Pack - Image 1](https://m.media-amazon.com/images/I/41LFFAcQqRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ quality product ! *by V***L on 17 January 2026* best ! gifted to electical contractor ! he was also happy ! ### ⭐⭐⭐⭐ Works perfectly fine, easy to assemble with little knowledge of electrical ... *by R***. on 8 March 2018* Works perfectly fine, easy to assemble with little knowledge of electrical appliance.
