Review: Best - Good working Review: Good Quality Product - Lasted more than 3 years - I installed this product ( from this company ) more than three years ago on external lamp posts in my garden. Out of 6, two failed now after daily switching cycles through hot summer and heavy monsoons. That's better than expected and I would recommend this to anyone who wishes to have daylight/night switching without the headache of remembering to physically turn on the lights and turn them off every day. Just remember that they need to be installed so there is no other light ( street light ) falling on them otherwise the sensors get confused and start switching on-and-off continuously, or just remain off assuming its daylight. ## 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 | #92,447 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #850 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 2,241 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 | | 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 ![Blackt Electrotech 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) ![Blackt Electrotech Waterproof 230Volt Auto Day/Night on and Off Photocell, Light Sensor LDR Switch for Lighting 2 Pieces Pack - Image 2](https://m.media-amazon.com/images/I/71FPf6h3Y-L.jpg) ![Blackt Electrotech Waterproof 230Volt Auto Day/Night on and Off Photocell, Light Sensor LDR Switch for Lighting 2 Pieces Pack - Image 3](https://m.media-amazon.com/images/I/71GQIS2GoVL.jpg) ![Blackt Electrotech Waterproof 230Volt Auto Day/Night on and Off Photocell, Light Sensor LDR Switch for Lighting 2 Pieces Pack - Image 4](https://m.media-amazon.com/images/I/61BCY8G0Q2L.jpg) ![Blackt Electrotech Waterproof 230Volt Auto Day/Night on and Off Photocell, Light Sensor LDR Switch for Lighting 2 Pieces Pack - Image 5](https://m.media-amazon.com/images/I/51UITmuZcUL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best *by J***H on 14 May 2026* Good working ### ⭐⭐⭐⭐ Good Quality Product - Lasted more than 3 years *by R***A on 27 December 2020* I installed this product ( from this company ) more than three years ago on external lamp posts in my garden.

The only thing to be kept in mind is that you should place it as mentioned by the manufacturer.... or place this device on the eastern side of your building (might have to pull wires , if the light to be used is at western or some far place... Placing at eastern side will turn off the light at around 6am and turn it on by around 6.30-7pm depending on the lighting at your area. Its working perfectly for me for past 2 years. Highly recommended. You can know the quality of the product by just looking at the quality of the copper wire used. ## Frequently Bought Together - Blackt Electrotech Waterproof 230Volt Auto Day/Night on and Off Photocell, Light Sensor LDR Switch for Lighting 2 Pieces Pack - Blackt Electrotech BT31P2 White Water Proof 230Volt Auto Day/Night on and Off Photocell, Ldr Sensor Switch for Lighting (5 Pic Pack), Relay, 1_way - Quick Sense (Qs-302): Day/Nights Auto on and off Plastic Photocell Ldr Switch 220V for Home Automation, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/404523312-blackt-electrotech-waterproof-230volt-auto-day-night-on-and-off](https://www.desertcart.com.ar/products/404523312-blackt-electrotech-waterproof-230volt-auto-day-night-on-and-off) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-25*
