Review: The quality is good… but the size of the sensor is too big… I thought it would be of 1 inch… but it is almost 3 inches…. Overall ita nice…
Review: It is over all a good product. 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.
