Motion Sensor Light Bulbs, 13W (100Watt Equivalent), Motion Activated Dusk to Dawn Security LED Bulb, 5000K Daylight, Energy-Efficient, for Indoor and Outdoor Lighting, Porch, Stairs, Hallway 2Pack

Great motion lights for my patio. They illuminate very well. I can tell where the dogs are at night. I have had them for a few months and they have worked exactly as advertised. Well worth the money I spent. I am sure they will be cost effective because they do not stay on too long. Just right.

Having tried an adapter with an integrated sensor used with a non-sensing bulb, I found that the application at hand had a socket that partially covered the sensor on the adapter and thus failed to meet the need. So, this product, with an internal sensor, turned out to be a great choice. The light levels that trip the sensor on and off correspond to dusk and dawn for a fixture that is on a covered porch. The 3000K color temperature is warm enough to emulate that of an old-tech incandescent bulb. The 100w equivalent rating is justified - almost too bright, so if there were a 75w equivalent that might be a better choice. All-in-all, great. Highly recommended. I'll let you know in 20 years when this bulb is expected to expire. UPDATE: About a week into the application described above, the first bulb failed - will not light up under any circumstance. The test is valid because the second bulb lights up in the dark as it should under identical conditions. One week is not "twenty years." UPDATE #2: The failure reported in the above UPDATE was preventable. After exchanges of messages with the seller, and the astoundingly clear and open communication on the part of the seller, I understood that these bulbs are unlikely to be compatible with fixtures that have a dimmer in their circuits. Running the bulb at less than full brightness (accidentally) apparently fried the first bulb and it is not usable. The second bulb displayed a lot of flashing at some point, but it has survived. I thus attribute the problem to my ignorance of the dimmer incompatibility, not the product quality. I did recommend that the seller make it clear in the listing that it is likely the bulbs will fail with dimmers, perhaps not all, but even if they do work the dimmers should be kept at full brightness. My thanks to the seller for enduring this adventure with me, and for clarifying the problem. Excellent customer care!

Fully automatic, one at dusk, off at dawn. No flutter or blinking, just works great!

These lights are awesome! but, there is no way to keep them on if you are in the room. A little longer of a timer would be cool, but I still love these for my garage. Easy to set up, color is great, durability seems good as they have lasted for a few months so far, function well and I would say a great value for the money for sure!

I've bought a different brand before and they're still going strong after a couple years. Great for places like closets, washing machine areas, basements, hallways. Good detection, very consistent.

This is a great lightbulb and does exactly what it needs to. On at dawn, off at dusk. This is a nice warm light which is what I prefer vs the bright cool white lights that are LEDs. This is a long lasting bulb since it isn't on all day long!

Absolutely love these! Very bright, and instantly come on.

Easy to install and easy to use. Just keep the switch on and its motion censored. I used one for my basement stairs and one outside. Works fine with glass casing.

work as described. 100 watt incandescant equivalent.

Works as expected, the only issue is the listing description. It states it’s warm white with 2700k but it’s definitely not warm white. It’s more 6500k (cool white) and I know this because I have smart lights and have everything set to 2700k, these sensor light colour is too cool. Quite annoying as I intentionally bought warm white as cool white is very uncomfortable for some people with autism.

These bulbs work better than I expected. They're very sensitive, and they work even when the sensor is inside a glass fixture, as long as the bottom is open. At first I thought I'd have to get a socket extension so that the entire sensor would be on the outside, but it turns out I don't need it.

Terrible experience, the description stated pack of 3 and I only received 2. Both bulbs in cool white instead of warm white. What a waste of time!

Super handy for work and storage space!
