Simba Lighting LED A19 Dusk to Dawn 6W 40W Equivalent Bulbs 120V E26 Base 5000K Daylight 4-Pack

Dusk to Dawn lightbulbs use sensor-eyes to detect available surrounding brightness to turn on-off lightbulbs. Simba is the only one I have determined it works as advertised. I moved the “on” lightbulb from a dim to a bright area, it turned OFF, while moving back to the dim area, it switched back ON. The other brands of Dusk to Dawn Lights which I had tried would NEVER come close to SIMBA brand.

I was skeptical about these bulbs. But I'm very happy I chose to take a chance and buy them. They are a bright clean white light, come on at dusk and turn off at dawn. Illuminates down my dour car driveway to the road. Time will tell how long they will last. Would recommend.

They work great coming on at dusk and going off after sunrise. Do not know the longevity of the Bulb. Save you the trouble of turning your lights on in the evening and off in the morning.

Absolutely LOVE them!! Takes the worry out of “did I put the light on”???? Great for anyone, but fabulous for older people on a walker to not have to walk far to light fixtures. Yay! Thank you for having them!!!

excellent dusk/dawn sensitivity even inside glassed lamp fixture

Great bulbs for my outdoor lighting ad no turning switches on and off anymore. 40 Watt is perfect lighting for my yard and front porch.

Not at all what I expected. The light is extremely bright, wish there was a way to turn the brightness down. It takes a long time for them to go off, even when it's bright in the room.

doesn't always come on at dusk

4 Dusk to dawn light bulbs , 1 did not work,stayed on all the time.

Wanted a replacement for a 40W incandescent bulb. This did NOT work, even though the rating says it should. It “flickered” when I installed. Assumed that was because there was enough light to turn it “off” but not enough to turn it “on”. Waited until dark. No luck. Threw them all away.
