Elrigs LED Motion Sensor Bulb with Dusk to Dawn, 5W (40W Equivalent), E26 Base, Warm White (3000K), 2 Pack, 24 Feet Induction Distance

I tried couple of "radar motion detector lights" before, none of them worked. I was pleasantly surprised that these bulbs worked despite my glass enclosed porch lights in front of my garage are about 8 feet off the ground. They detected motion without any issues and they only come on with motion and at night time. We love these bulbs, highly recommended !

These seem to work well. The turn any light fixture into a motion detecting fixture. Great idea!Update 2/1/2017. These have a two year warranty and they are inoperable at this point. Like the other reviewers reported the motion sensor is VERY sensitive and there are a number of false lightings.

The motion sensitivity is actually too good. I can't use this in a number of places I would like to because it will turn on when i'm in a nearby room or walking down the hall outside where the bulb is. [Note: the motion sensor works through walls and doors as mentioned in the description] For the couple of locations where this works without all the false triggers, its fantastic. I'm using it in an unfished part of the basement (only the bulb farthest from the furnished section we use) and in an entryway by the garage that is not highly trafficked.

These work great. No problems at all (and they have a nice neutral-warm color of light). I'll be buying some more. Highly recommend.

CONCLUSION: Over sensitive. Stays on for only 20sec. This combination causes it to come on and go off continuously. Minus two stars.I wish there was a "stay on" option for when that's required (there is none).I'm using it on a covered porch in a fully clear glass enclosed wall sconce and it fires when there's movement within about 30'. (It appears to be sensitive to shadows - so movement even outside its direct line of sight sets it off.)For the price - I'm going to leave the bulb in place, so long as the neighbours don't complain about the fairly continuous switching on & off of the lights.PROS:Well made item. Well packaged.Does not come on in the daytime.Works from inside a glass wall sconse.The 4K colour temperature on my bulbs appears to be just right.CONS:Over sensitive - comes on and goes off continuouslyStays on for only 20sec.Lacks a "stay on" option for when that's required. (Other movement lighting I've had allows 'stay on' with a rapid on-off-on sequence. Other lighting also allowed a certain amount of sensitivity setting so that moving branches etc are less likely to turn them on.)

The bulb is very sensitive and does pickup movement inside or outside of kitchen door so that if very effective for safety. We are very happy with these new bulbs.

Not so good for the price. One burned out after just a few days

Work as promised. Specifications are correct. No problems after 2 months.
