Do these bulbs need a timer or switch?

No. Each bulb has a built-in photocell that turns it on at dusk and off at dawn. Leave the fixture switched on and the bulb does the rest.

Will they work in a standard outdoor fixture?

They use a medium screw base, the common size for porch and flood fixtures. Check clearance first, because the sensor makes the bulb longer than a plain PAR30.

Can I use them indoors or in a dimmer?

They are meant for outdoor dusk-to-dawn use and are not dimmable. Indoors they would stay off in daylight and may switch on in dim rooms.

Why does a bulb stay on during the day?

The photocell reacts to light at its tip. Deep shade, an overhang or a nearby lamp can make it think it is dark. Moving the fixture or shielding the sensor usually fixes it.

How do they compare with halogen PAR30 flood bulbs?

They give similar flood coverage with much lower power draw and cooler running. The trade-off is the sensor bulk and no dimming.

Our take on the Sunco Lighting 4 Pack PAR30 LED Bulb

A four-pack of PAR30 LED bulbs with a built-in dusk-to-dawn photocell, so they switch on at dark and off at daylight without a timer or smart switch. The PAR30 flood shape throws a wide, directional beam that suits porch lights, garage fixtures and security floods. They fit standard medium-screw outdoor fixtures and draw far less power than the halogen PAR30 bulbs they replace. The catch is the photocell: bulbs stay off in daylight and can be triggered by nearby lights, and the sensor adds bulk that may not fit tight cans.
