A brighter PIR motion bulb: 12 watts, 1100 lumens, daylight white.
Light It Up on AmazonA motion sensor bulb replaces the bulb in a fixture you already have. Leave the wall switch on and the bulb decides when to light. All three GREENIC motion bulbs stay dark in daylight.
The choice comes down to the fixture. An open fixture or a bare socket takes a PIR bulb. A closed glass lantern needs the radar bulb, because infrared cannot see through glass.
None of them dim, and none of them work with a smart switch.
