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

Have been using for more than a year. No complaints. Easy installation. Very useful as it saves lots of electricity as we tend to switch off the lights. Very Good quality as I have installed outdoors in rain and sun.

Product quality is good, easy to install and configure, but it’s extremely sensitive to even the light from the bulb, it just keeps automatically switching on and off, I had to wrap two sides with cardboard so that it stays on after dark, a dial to adjust the sensitivity could have been given to adjust the levels of sensitivity.

Have used this sensor in my parking lot so that it turns on the common lighting system when it gets dark and automatically turns off when it gets daylight. Much to my astonishment the packing was neat and clean and 5 such devices for less than 1000 is a real value for money. Did go through the circuit and the components used and I am much impressd. Not sure of its durability if I am going to use it for exterior light as the Sun is pretty hard on plastic objects in Chennai. But sure the product will last long if used in non sunny areas. Just the manual could have been more detailed for a non technical person... net net a very excellent product.

This is very good product but 2 item stopped working after 2 month, rest 3 still working since last 6 month

Great

Works well. But light sensitive is bad. The light have to be very bright for it to switch off

Value for money good product

good product
