Feit Electric A19 60W Equivalent 2700K Dusk-to-Dawn Bulb

Worth it for contractors who need automatic outdoor lighting without timers or switches. The built-in photocell sensor turns on at dusk and off at dawn reliably, and the 8.8W consumption saves 85% versus incandescent while delivering 800 lumens. At 90+ CRI, colors look accurate under security lights — important when you’re identifying vehicles or checking on properties at night.

Skip it if your fixture blocks natural daylight from reaching the sensor. The photocell needs exposure to work correctly, and these bulbs won’t work with dimmers — they’re strictly on/off operation. Feit’s pricing often beats Philips at major retailers, making this a cost-effective choice for basic dusk-to-dawn applications.

Automatic Operation and Energy Specs

The sensor eliminates manual switching entirely — no programming, no batteries, no maintenance beyond eventual bulb replacement at 15,000 hours. That’s 13.7 years based on standard 3-hour daily use, though Montana’s long winter nights mean you’ll see closer to 10 years in real-world use.

Specification	Value
Actual Consumption	8.8W
Light Output	800 lumens
Equivalent Brightness	60W incandescent
Rated Life	15,000 hours
Energy Savings	85% vs incandescent
Operating Voltage	120V

Some models feature an adjustable sensor base that lets you orient the photocell toward the sky — handy for fixtures mounted under eaves or partially shaded locations. The bulbs work in enclosed fixtures as long as the sensor isn’t completely blocked from daylight.

Light Quality and Installation Requirements

The 2700K soft white temperature matches traditional incandescent warmth, avoiding that harsh blue-white security light look. At 90+ CRI, skin tones and colors render naturally — you can actually tell a blue truck from a black one in your driveway.

Installation couldn’t be simpler — screw it into any standard E26 socket with the A19 bulb shape fitting anywhere a regular bulb goes. Just ensure the fixture allows natural light to reach the sensor. The non-dimmable design means it’s incompatible with dimmer switches — wire it to a standard on/off circuit or leave the switch in the ‘on’ position permanently.

Common applications include outdoor porch and patio fixtures, walkways and path lighting, home security lighting, garage exteriors, and indoor areas where automatic nighttime lighting is needed. Think mudrooms that need light when you come home after dark, or basement stairways where a nightlight prevents stumbling.

Frequently Asked Questions

Q: How sensitive is the dusk-to-dawn sensor?

Reviews report reliable sensor operation in direct light, but sensitivity issues can occur in shaded fixtures. The sensor needs unobstructed exposure to ambient daylight — not necessarily direct sun, but enough natural light variation to detect day/night transitions. Under deep eaves or in heavily shaded fixtures, the sensor might stay on continuously or cycle erratically.

Q: What causes these bulbs to flicker or fail early?

Flickering typically happens when installed on dimmer circuits — these bulbs require standard on/off switches only. Limited longevity in some units has been reported, though the average 3-star rating across 4 reviews suggests mixed experiences rather than universal failure.

Q: Can I use these in totally enclosed fixtures?

Yes, they work in enclosed fixtures, but ensure the sensor isn’t completely opaque to daylight. A glass globe fixture works fine. A solid metal housing with no light access to the sensor won’t trigger the automatic operation.

Q: How do these compare to motion-sensor lights?

Dusk-to-dawn provides constant illumination all night, while motion sensors only activate when triggered. For security, constant light deters better than motion-activated. For energy savings, motion sensors use less power. Choose based on whether you want all-night coverage or on-demand activation.

Q: What’s the actual warranty coverage?

Manufacturer provides a 1-year or 2-year limited warranty depending on model. Standard store return policies like Home Depot’s 90 days also apply. Given the 15,000-hour rated life, most failures happen early if they’re going to happen at all.
