Sunco Dusk to Dawn Light Bulbs Flood Light Outdoor PAR30 LED, Photocell Sensor, 11W=75W, 5000K Daylight, 850 LM, IP65 Waterproof, Light Sensing Auto On/Off Security Porch Light, UL 4 Pack

Work so far. Put two in a floodlight and two in my down porchlights. They come on at dusk and go off at dawn. Perfect.

Out of 4 lights, two were defective. Thus, from my experience, if you need 4 lights, order 8.

Work really well so far.

The photo sensors works well and these bulbs provide a bright light. No issues with either blinking or pulsating light.

Dusk to Dawn bulb works well on our front entry.

These bulbs work way better than I thought they would. Great price and helped rid the dark spot up front.

We live on an acre of land, and these light up the area behind our house very well! It is nice not to have to remember to turn them on and off each day. I cannot yet comment on their longevity. They do not seem to have caused much of an increase in our electric bill.

While I can’t yet rate the longevity, I am thrilled with these dusk-to-dawn lightbulbs. Instead of having to have the old sensor outdoor fixtures replaced in my older home, these solved the problem and come on when it’s dark, off when it’s light without my ever having to think about it. Before, I either left the lights on all day or had to run around to several switches all over the house. It’s nice nog to have to think about it! They throw out a lot of light, too, which is very nice. I LOVE them and have turned a few other people on to them, who love theirs, too. I did think one wasn’t working one night when I came home and opened the garage door - but the sensor was going it’s job and going off because the garage light lit up the whole place! When the door closed, light was back on!

Works efficiently. Does just what I want it to do. Go off in the day and brighten my backyard at night. Perfect

So far, its working as expected without any issues. It turns on and off when its suppose to.
