Customer Questions & Answers

Light is continuously on

My lights are always on no matter what settings on the bottom, light never goes off, they say it may be in override mode but not sure where or what that means...Anyone? I have followed the troubleshooting guide but nothing seems to get it to turn off, can it somehow be mis-wired? or would that not make it work period?
Asked by: Rickracko
The answer ROCKGARDEN provided is true unless they (Home Depot) has a different/newer model. If this happens the store will not provide the next model. I believe this is true even if you have a receipt. They tell you that you have to call the home office of Home Depot. It is pot luck from that point on.

How do you make the light come on at dusk and stay on all night?

We have tried following the instructions and can't make it come on automatically and stay on. We always have to walk in front of it to make it come on.
Asked by: Sophie123
As noted in the instructions, if you turn the power off and back on twice in 3 seconds, the light will stay on until dawn. This needs to be repeated each evening; the setting is reset at dawn.

can this unit be mounted horizontal

Asked by: j438ufds
most of motion lights can be mounted horizontally, the only thing you want to watch for is that there are no openings or switches that would be exposed to rain or that would hold water. Usually the sensor can be rotated so that does not happen. Pat

can this unit be mounted horizontal

Asked by: j438ufds
yes... just adjust the junction box accordingly (plastic at home depot $6). Just make sure the sensor is positioned to the "area of focus". O | San Jose, CA

180 Degree Motion Outdoor Activated White LED Security Floodlight is rated 2.5 out of 5 by 8.
Rated 1 out of 5 by from Garbage This light is complete garbage. I bought this light new $100. After about 2 months the sensor stopped working. I called the 1800 number and they said to return it for a new one. Got a second one. Another piece of junk. The sensor had some sort of a glitch. It stay on all night and turn off. Sometimes it stay on all day with the sun hitting it. I called the company and complained they said they will replace it. You think the third time was a charm. No way. This light again has issues with the sensor. It worked for almost a year til it started to act up. This is very disappointing. I spent alot of money for nothing. The only great thing about it is the LED lights are very bright.

Rated 2 out of 5 by from Nothing but trouble with these Defiant LED sensors. Constantly on during the day, on/off all nigh... Nothing but trouble with these Defiant LED sensors. Constantly on during the day, on/off all night, dusk till dawn feature has never worked... Currently have to manually shut off power every morning and turn back on at night so it can turn on and off all night long. Not worth it.

Rated 1 out of 5 by from Sorry, but this is junk Really liked this light when I installed it about a year ago. Good brightness, good coverage, motion sensor worked well. THEN, after about six months one of the lamps stopped lighting, but the other worked, so I left it up. Then after another few months the second light stopped working. No light at all. Tried turning power off and on - nothing. Won't light under any circumstance. Called the warranty number, but since I can't find receipt they won't help. $80 down the drain. I wouldn't buy this or any similar light from Defiant if you are smart, as it won't last.

Rated 1 out of 5 by from product did not match manual. Product was previously opened and parts were missing. The weatherproof gasket was broken. Also, the wiring in the device did not match the manual. I had to look it up but was still not convince. The manual said to call first before returning to the store. They said to return it to the store.

Rated 4 out of 5 by from Great sturdy outdoor light. It's my 2nd purchase. I also have purchased 3 light one over 2 years ago. This works great which is why I specifically ordered it online since Home Depot no longer carries it in their store. It takes couple tries to get it to length light stays on. I also had previously purchased one act funky where it would just stay on. Luckily I had it hooked to a light switch and simple turning off and on just reset and worked fine. It occured twice. It is very bright and turn on every time I walk to same spot. It is sensitive that a large spider and june bug/beetle was triggering the sensor couple times. Sometimes when it gets windy, my tree would trigger the light. And opening my garage where the lights are attached to has triggered the light. It has seen many rain storms and still works fine. It's LED so it uses less energy (Haven't actually tested it) and should like a long time. One thing I'm glad is that I have attached them to a light switch so if it doesn't turn off I can reset it of in particularly windy days, I can just leave it off for a night.

Rated 4 out of 5 by from Super bright This light is super bright. Motion detection worked well for a while. After a month, the light was on all the time, day or night. No hassle return (bought same light again in the store, we'll see how it works).

Rated 2 out of 5 by from Manufacturing error One out of four of these light fixtures that I bought actually performed correctly. One stayed on during the day, another stayed on during the night and a third was delivered in a box that looked as it were used for a football in the Super Bowl. I didn't bother to open it. Took it back to Home Depot. Looking at other unfavorable reviews tells me that there is a problem with the motion sensors from the factory.

Rated 5 out of 5 by from Excellent Motion Activated White LED Security Floodlight Excellent price, very easy to install/set up, and the bright lights cover a wide area. Appearance is okay as the sensor arm is awkwardly long for my taste.
