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

So far,EXCELLENT! These bulbs function as I had hoped,they are sensitive to dawn and dusk and seem to be well made.Time will tell.

3/4 blink continuously or just don’t work.

The picture shows a flood light, but it is not. Its a regular light bulb!

These are great!!! They do not detect motion they have light sensors engineered into them so that if you leave the switch in the “on” position your porch or flood lights will automatically turn on once they sense that the amount of light has diminished significantly. I have four of these installed for my front porch and another two in a flood light by my garage. Several months ago I moved quite a ways away from civilization and it is very dark out here. I left to run errands early in the day and it was dark by the time I returned home. It was very very dark and I didn’t leave any outside lights on, since it was daylight when I left. I ordered these that night after I found my way to the house. They have worked great since they arrived and I don’t have to worry about whether I turned on lights before I leave or wonder if I will be home before dark.

Bought 6 bulbs and 1 died within 3 weeks. Otherwise works very well with good brightness

These lights are on the perimeter of our American Legion Post. The save electricity by turning themselves off at sunrise...

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

Was blown away with how well these work. A little small around the base so the rubber weather proofing on my fixture doesnt completely seal, but it could be my fixture and not the bulbs. Plus they are under my eaves so its fine. Would buy them again.

would buy again

Have installed two of the lights in a deck flood light. Very bright. Good coverage.
