Elrigs Motion Sensor Light Bulb with Dusk to Dawn, E26 Base, 7W LED(60W Equivalent), Cool White(6000K), Motion Sensitivity, Time and Twilight Setting Adjustable

This bulb works great, the motion detection works even from inside an outdoor fixture with glass sides. The motion sensitivity is adjustable as is the brightness of the bulb and the length of time it stays on. It stays off in the daytime even if it is on a porch with a roof over it and it is a cloudy day. We have much less bugs flying around our back door at night with this light because it only is on for long enough for us to get out of the car and come in. It also comes on when we open the door to go out. Our old light was on all night and attracted lots of bugs. This is the first motion detection light that we have used that works correctly in this location by our back door and it converts a standard porch lamp into a motion detection lamp without needing to replace the whole fixture.

This review is for: "Elrigs Motion Sensor Light Bulb with Dusk to Dawn, E26 Base..."These bulbs are excellent with motion detection features that seem better than those with PIR sensors. The ability to adjust threshod and sensitivity to light/darkness conditions, distance of detection, and time that the bulb stays on are a huge plus. These adjustments allow you to customize key functions of the bulb that are very useful to be able to tweak. For example, sometimes a non-adjustable bulb can be too sensitive to motion such that it comes on all the time. In other instances the sensitivity may be too low and the bulb does not come on when you want it to. These bulbs allow to adjust the sensitvity / threshold to key parameters. It can take a bit of tweaking but once it's done, the result is that the bulb comes on when you need it to.The brightness is a perfect balance - not too dim and not too bright. I purchased the kind that emits a warm/yellow hue which works well for me, but they also have a bright white version.Overall, a great product and a great experience so far. I will update this review based on further experience if needed.

Wanted a way to light my garage automatically. Light kept getting left on by others. Used a PIR motion sensor for this purpose for years but in the Texas heat with the additional heat of cars parked in the garage, PIR motion sensors become a lot less sensitive and unreliable. So I was excited to learn about radar motion sensing technology. Tried it in another much more expensive light but it failed to automatically turn off as advertised. Found out later that it was reading movement thru the walls in adjacent rooms so I figured well back to how it was before. But when I found this bulb which BTW is the only light with radar motion sensing technology I could find that ALSO allows you to adjust ALL settings including the radar motion sensing range, ambient light sensitivity, and time duration I figured that I finally found the solution and yes it works as expected for the most part. I did have to spend about 45 minutes tweaking the radar motion sensitivity setting for my particular situation...made sure it was not reading movement thru walls next to my garage, which is attached to my house. At first, by default the range was turned all the way up but I turned it down and the light stays off regardless of activity in nearby rooms now. The radar motion sensing sensitivity setting should be a must for all lights using this technology. I cannot imagine the number of disappointed customers there is when the radar motion sensing feature is too sensitive and no way to adjust it...also not sure what the other manufacturers / electrical designers are thinking with leaving that feature out, even the early first generations of outdoor motion sensing lights had sensitivity adjust options for motion. This radar motion sensing technology is very new to the home consumer electronics market and I am really surprised that feature does not seem to be even requested by many reviewers on similar competing products. Regardless this company did right by finding a way to bring that feature to market at an affordable price point.-UpdateAfter having this for a few weeks I am unfortunately returning it. I have NOT lost faith in this product, it just does not work good enough for my situation/environment. The light will detect motion for when me and my wife when entering the garage but NOT our small children who are still afraid of the dark. Perhaps our minivan blocks the radar motion sensor's ability to detect movement at a lower height even though the bulb is centered over the minivan. Also, I noticed that the light does not consistently turn on when my wife or I enter the garage, not sure what is going on there. At first, I thought it was the ambient light senor deactivating the bulb for when the garage entry door opened and flooded the garage with light from the inside of the house but I adjusted the light senor to turn on even in conditions with a lot of light and still had the same issue. So, back to how it was before until I can find a reliable solution yet again.

I bought a pair of these a few weeks ago to use on my deck and my outside garage light. They worked great with amazing sensitivity to movement at a very reasonable distance. In fact, my next door neighbor asked me where I got them, because he had seen the one at my garage come on whenever he passed to enter his driveway. Wanting some more to put in my stairwell, I tried another brand that sounded good and cost less.....big mistake! So, I returned them and reordered from Elrigs, and I am glad I did. These work just as well as the first order. Putting the new ones in my stairwell didn't produce exactly the results I wanted. It's a squared off U shape. Going downstairs, the bulb at the upper landing picks up the movement even before I reach the head of the stairs. The one at the lower landing does not pick up movement until I almost reach it. That seems to happen, because I am coming up from a lower level, putting me below the bulb. I do not believe that is an issue with the bulb and have come up with a work around. If I need anymore, I will buy these again.UPDATE: One of my bulbs failed in about 8 months, so I contacted the Seller. There was no hassle at all, and I now have a new bulb that is working very well. That's customer service!
