After buying and installing, one light bulb has burnt out in about one week. There were days when it was raining, but I think that it is too early. I thought that it would be nice if I had about a year because the price was cheap .... Also, since it is a product that is supposed to be cut off, you should purchase one spare item from the beginning at the manufacturer, or handle spare parts at the monotail.
I think that it is a good product for the price. Adjustment of delicate distance and range is not good. (I could set it properly according to the display properly) But I think that the sensor part is still better to separate type.
