This is not a motion sensor lightbulb that has to have the little bulby part on the end open away from the lampshade. This light bulb uses radar. You can have it hidden in a beautiful light fixture with a beautiful shade and not worry it will still be effective. It can sense motion in the other room and turn on the light so that you will have light when you open the door. It’s super wonderful for people who need to get up at night and go to the bathroom and see where they’re going or go to the kitchen to get a drink of water in the middle of the night. You don’t have to search for the light switch or wonder if the lights are going to come out and you don’t have to worry about turning them off because a few seconds after you leave the area they turn off by themselves . Another good thing about that is the kids can’t sneak in the door and go up the stairs at night pretending to be in from their dates earlier either as the lights will turn on and you will know that they came in the door. It’s a wonderful product. I have it one lamp in every public room and bathroom with one of these bulbs. You turn it on and forget it. It only turns on and makes light when it is dark in the room and there is motion somewhere around it. Love them.

Works with the downward facing lamp.First not sure why it doesn’t run on then tried at night it works perfectly.

Super bright
