- Will this bulb work in a standard porch light?
- Yes, it uses a standard E26 screw base and fits most porch, garage and hallway fixtures. Check clearance, since the built-in sensor makes it longer than a plain A19 bulb.
- Does it need a timer or app?
- No. The photocell inside the bulb switches it on when light drops and off when daylight returns. There is no app, hub or schedule to set.
- Can I use it with a dimmer switch?
- No. The bulb is not dimmable, and a dimmer can cause flicker or shorten its life. Use a standard on/off switch.
- What color is the light?
- It is 5000K daylight white, a cool, bright tone. There is no warm-white version in this model, so it suits utility spaces more than cozy living rooms.
- Why does it stay on during the day?
- The sensor reads light at the bulb, so deep shade, a covered fixture or a nearby lamp can keep it on. Move it to a spot that sees open daylight.
- How many bulbs are in the pack?
- Four bulbs. That is enough for several matching fixtures such as a front porch, back door and garage.
