Motion detection.

I bought this product for friend whose lights went out on the side of her house. I tried to find bulbs to the specs described until found the ones advertised on Amazon. Received the two bulbs the next day and my friend showed me how bright they look. Love these lights, brighter than the ones she had for years. Thank you.

We have 3 dogs and these are great . We finally put them up and they come on as soon as it got dark and lite up the yard very well . Having 3 dogs going at night we can see them now and feel very safe with these very bright light

Great Product which I would definitely buy again

I was skeptical when I purchase these because some of the reviews were somewhat negative. I have Dusk to Dawn light bulbs in my front yard light in my porch light and I absolutely love them. I decided to take a chance and order these for my spotlights and I am so glad I did. I purchased the warm White because they match my front yard lights . They were a wonderful choice in color . They are not motion detected they are Dusk to Dawn. Now I just leave the switch on and when I come home its light and bright. Ive only had them in for about a week so I cannot rate the longevity but so far so good I am very pleased with them and highly recommend.

The fact that the sensor is integrated in the bulb itself enables the bulb to be more reactive to light. This works well in a shaded area. Before with a different product (a sensor which the bulb screws into) the light would be on much of the day. I am very pleased with these lights.

I received then today and was eager to install. The installation was super easy, just unscrew the existing and screw in this item flick the light switch in the on direction. The lighting is clear and bright. Very happy.

This Dusk to Dawn bulb works really well! It comes on and turns off automatically with the amount of ambient light present. We use it in the light over our basement garage. It throws a good amount of light, so we can easily see to enter the garage at night. Furthermore, we dont have to worry about forgetting to turn on or off the lights the photoelectric sensor does that for us. I highly recommend purchasing and using this energy efficient LED bulb!

I use these lights for my backyard. Theres no light switch for the floodlights so I needed dust till dawn lighting. Saves energy cost.

So far, so good
