I can be inside with front door closed and 2 solid wood French doors closed 6 feet away and the lights come on. How, I have no idea. **Q: Why do they just stay on. I put it in a lamp in the basement where there is no motion, and it never shuts off?** A: There may be something in the basement triggering it. Try it in some other location. If it stays on there you may have a bad bulb. **Q: What size is a light bulb in inches?** A: It is approximately the same size as an old style incandescent light bulb that one would put into a table lamp or ceiling light socket. I'm using mine in an overhead recessed porch light fixture socket **Q: What can I do so that the sensor does not detect motion in a specific direction?** A: Shield that part of the light bulb. Hope that works. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars 1 out of 4 doesn't work but seller made it good *by T***6 on Reviewed in the United States on November 24, 2023* This is a difficult review to write. On the positive side, these work inside coach light fixtures where the other motion detector technology does not. They are plenty bright and the three that work pick up motion appropriately, stay on as long as motion exists and then shut off after 17 seconds when the motion has finished. Great for security around our home since I don't want the lights on all the time but also don't want anyone on our property, uninvited at night.The difficult part comes in that one of the 4 bulbs doesn't work property - it goes on and off constantly, motion or not. Moved it to another fixture but still does the same thing (all three are on the same circuit). I'm concerned that if I return it along with a good one (they come in packs of 2 so I'd have to return 2) and then get back two that don't work properly. Reading other negative reviews, the actions of the one that doesn't function properly seem to be a failure point for the product.On the other hand, once I contacted the company, they immediately made good on the defective product - best response from a seller on Amazon that I've ever experienced. I'm sure now that I will have 4 working bulbs. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It works great. Detects all motion on my property *by P***R on Reviewed in the United States on September 13, 2024* Detecting the motion on my property ### ⭐⭐⭐⭐ 4.0 out of 5 stars works a little too well *by M***O on Reviewed in the United States on November 18, 2023* Ok, i'm surprised that these flood type lamps are pretty bright. They are 5000k so they are that whiter light that is great to brighten up dark areas like my backyard. I have two bulb sockets that were mounted high near the the top corner of the roof to illuminate the backyard. So the two lamps are spaced about 45 degrees apart to shine on the whole yard. They aren't pointed down but maybe a little farther out to the corners of the yard. With that said, they are mounted pretty high, over 12' and they are detecting some sort of movement. The lights will come on every 5 seconds. Almost suspect that there's something triggering it besides movement as it's a regular cycle. I"m going to have to turn this off at night which defeats the purpose of this light as it will bother the neighbors as it flicks on and off every 5-10 seconds. So i'm going leave it on hoping that there is some sort of break in period, maybe the bulbs will get dustier and block some of the movement sensing? But i have to say, for a small light and movement sensor embedded inside the lamp itself, it sure is working beyond what i thought, as it said it should work at about 3-5 meters. Anyways, 4 stars for now as they are bright and the light is more then i need, but the motion sensor is a little bit too sensitive.Update: i put a 1" piece of electrical tape cut in half length wise on each side of the 3/4" sensor or what i assume is the sensor in the middle of the bulb face. So like 3/4" on each side i put some tape. I'm not sure if it's the tape, but at least it turns off for longer durations now. It's still detecting motion quite easily, but usually after 12am it stays off at longer intervals. So not sure what you make of that, the trees moved less? possibly. At first i put the 1" piece of tape covering the center and it didn't seem to want to turn off for whatever reason. I want to try put a few more pieces of tape on it as i think this will solve the constant on and off. i think i'll position it so it covers half that middle black looking sensor right in the center. it was windy yesterday night so it came on excessively, so i hope it's not bothering the neighbors too much. The extra pieces of tape should desensitize it a little more and i think it'll be perfect.Update2: As temps been dripping after midnight its been staying off longer. Maybe 4 hours at the longest. Usually after midnight. I still will add two more small strips of electrical tape on the other two sides blocking just a little of the center sensor to desensitize it just a bit more. There does seem to be some animal movement triggering so overall they do work. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/227460254-motion-sensor-light-bulbs-a21-15w-5000k-1500lm-daylight-2](https://www.desertcart.sg/products/227460254-motion-sensor-light-bulbs-a21-15w-5000k-1500lm-daylight-2) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-21*
