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

The installation is simple--just screw it into a medium-based lightbulb socket. When I first installed it to test it, it gave no sign of life, so I unscrewed the bulb to check the socket to make sure it had power. And then I reinstalled the lightbulb. And waited a few seconds. No sign of life. I repeated this several times, with no success. I decided to reread the manual a bit more carefully in several languages before looking for return instructions. The English manual said to wait for 30 seconds or longer for the sensors to be calibrated for the environment before they start working. So, I installed it in the basement and left. After a few minutes, I came down to the basement, and voila, it came on as advertised to work! So, it turned out that I didn't give the sensor enough calibration time. Rereading the instructions, the calibration period varied depending on the language--English instructions, 30 seconds; German and Japanese, 5 seconds; Spanish, French, Italian, and Chinese, 10 seconds. Clearly, Germans and Japanese would give up on this in just a few seconds. The actual calibration time for these units might have been much longer than 30 seconds. So, before returning this unit, you should try to give it ample calibration time. In any case, it is installed on the porch and seems to be working properly.

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. -Update After 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.

At first I was mad...it would come on during the daytime. The directions were not clear...which is disappointing-it is important to have simple clear instructions. But the video explains it a little better. The Good-it's the only adjustable 'regular' size bulb that can adjust time duration, light sensitivity to come on day or night (in or outside) and feet away adjustment. I would get sooo frustrated, getting groceries, doing a small project outside and the light would go out after 30 seconds-back and forth ect...you have been there. After getting better directions, now I have a full 5 min. and another 5 when reset by motion. I thought about someone getting it right for an adjusting light bulb, and they did it. Congrats-5 stars :)

The biggest issue with this bulb is trying to get the sensitivity set. It will pick up movement through a wall better than it will when you're right in front of it, which is very. My purchased it to use in one of my bathrooms but that was an epic failure. I have since moved it to my porch light which at least does work better, but still have issues with it being too sensitive or not picking you up at all. Overall I would say this is not worth the money.

Very sensitive at short ranges (haven't tried long ones), good color, and good daylight awareness. Can't rate longevity after only one week.

I was pleasantly surprised with these bulbs. They are very easy to set and continued to work during a Montreal cold winter. Adjusting the motion detection is a trial and error (especially if you have a tree in front of the house and its windy)

bulbs work great but one was defective so I will order another pack. vendor was kind enough to credit me the full amount.

Fonctionne pas bien detecte a travers des mur.

The set up for these light bulbs is very difficult. There is no explanation as to what the different settings are or how to make adjustments. We will continue to use the ones we purchased but will look for a different solution for our other lighting needs.
