It was just installed. The sensors are not always working but maybe adjustment. I have three one on each door. Not to sure about how the bulbs are no lens cover lights are built that way. Lights are very bright when they work. Gave a three because of the sensors but would be higher if adjusting works. Not sure why one comes on during daylight should not no matter how they are adjusted. Price was good but I may have got what I paid for. Time will tell on quality.
