SANSI Motion Sensor Outdoor Lights, 15W 2000LM LED Flood Lights Outdoor, 5000K 4 Modes Security Lights for Outside Porch Yard Garage Patio, IP65 Dusk to Dawn Motion Detector Lights

Bought this to put outside a warehouse building and light up the outside of our exit door and parking lot for employees. This replaced a pretty standard 2 bulb fixture that had 1200 lumen bulbs (each) that had quit working. This is much brighter and fits our needs very well. The motion detector picks us up immediately as we come out the door even though we're 90 degrees to the side of it (the light is about 10 ft down the same wall that the door is on), and picks up motion well out into the parking lot for anyone arriving. The photo sensor works very well to prevent it from coming on during the day.The building has a 10 ft overhang across the front which covers a sidewalk area between the parking lot and building. The original light was in a ceiling junction box about 8 ft out from the building/exit door, and I had planned to just mount this light there. This light didn't work as well as the old light in that situation, but it wasn't a good location even for the old light, and the seller clearly stated this light is designed to be mounted vertically, not horizontally... so I'm not knocking any stars. I installed a new junction box on the wall, which was really the preferred set up for our situation regardless of which light fixture we chose, and simply installed a cover plate over the old ceiling junction box.I think the light can work well ceiling mounted in certain situations even though the seller doesn't recommend it and it didn't work for our particular situation, which I consider to be unusual. I'll go into more detail below about the ceiling mount issues for those interested that don't mind the length...The problem was the ceiling box was 8 ft out in front of our exit door (and a few feet to the right). We wanted the motion detector to pick us coming out of that door (behind the light) but also pick up movement in the parking lot (in front of the light), which means we were basically wanting to get 360 degree detection with 180 degree detector. So what we did as a compromise was turn the light fixture so that the motion detector was facing "sideways" instead of either towards the door or towards the parking lot. We then aimed the detector so that it barely caught the door opening to it's far left limit of vision, and we then lived with it's limited detection view of the parking lot to it's far right side.So we had a situation where the motion detector needed to look west, but the lights need to shine north, and the amount of swivel adjustment on the motion detector arm is limited. So basically the base of the fixture is facing NW, the adjustment on the motion detector was maxed out to get it looking west, and now the lights need to face north. The old light with 2 single independent light bulbs were easier to aim as needed, but with this light have long light bars on each side of 3 lights each, it was harder to aim them as needed.The problem is each light bar arm only has adjustment movement on 2 planes, and needed to have adjustment on all 3 planes for our situation. To get them facing north when the base is facing NW, they have to be turned so one side angles way down and the other side angles way up (an the ceiling becomes an issue on that side). That makes it look really bad not being symmetrical, and the low hanging side being more at risk to getting hit/broken. Also with the light fixture being 8 ft in front of the door and aimed away from the door (towards the parking lot), the door area only received "bleed light" and wasn't well lit.Now with the new junction box moved back on the same building wall as the exit door, the 180 degree motion detector provides full coverage of the entire area, the 2 plane adjustment for each light bar side is adequate, everything stays symmetrical/aesthetically pleasing, and the exit door is better lit as well as the parking lot.If you want to ceiling mount with motion detection, I think it will work fine as long as you can face the base, motion detector, and lights all in the same direction. You can rotate the motion detector arm 180 degrees on the ball socket joint to keep it oriented correctly and you can maintain a symmetrical profile when adjusting the light bar directions. We ran into ceiling mount problems only because we needed the motion detector to face one way and the lights to point a different direction. If you want to use this in dusk-to-dawn mode instead of motion mode, I suspect the light reflection off the ceiling could increase a flickering issue. I did not try ours in dusk-to-dawn mode, so I can't say for sure, but noticed other reviews mentioning flickering problems in dusk-to-dawn mode.

Great motion sensor light for the moneyEasy to instal

For the cost, seems to function as advertised. Easily reconfigurable for wall or soffit mounting. Bright enough.

I read reviews and looked at pics here before buying this light. Like some other products I've read bad reviews about, I had a suspicion that most of the bad reviews arose from a misunderstanding of the adjustments. I think this is the case here because the product works fine --> provided you read and understand the adjustments <--.Let me "de-psyche" the descriptions of the settings, or put them in better English. The four positions of the switch first -Test: This simply lets you walk around in front of the motion detector and check alignment. It overrides all other settings so it works day or night for testing purposes. Don't leave it in this position after you are done adjusting the sensor head.Auto: The "main" setting most people would use this for. It will detect motion and turn the lights on for a set amount of time, but only when the light sensor detects it is dark outside. This trip point has to do with the "Lux" control. More on that below.On Time: This is a poorly labeled function. Call it "Lamp Mode". All it does is make the unit act like a simple lamp - On or Off according to the AC power supplied by the breaker or wall switch. It just acts like a simple ON/OFF light, nothing more. All the other settings don't apply.D2D: Makes it a dawn to dusk light. It does NOT detect motion in this mode - the motion sensor does not operate here. However, it does depend on the Lux adjustment to set the point where the unit detects "dusk" or "night". I will explain this below.The Three AdjustmentsRange: I'd rename this. It's a sensitivity adjustment. You must consider the sensitivity adjustment AND the angle it's pointing at together - both need to be considered for range. For example, if you point the sensor downward at an extreme angle then you do not want the range (sensitivity) turned up too high or it will be triggering on caterpillars. If you want to trigger on people walking at the far end of a driveway, then turn up the sensitivity. Let me add that the motion sensor is an IR (infrared) sensor. What it really senses is heat. If any areas of heat change (motion) from it's static state it will turn on the lights.Time: Sets how long the lights stay on after motion has been detected. From about 1 minute to 10 minutes. Simple.Lux: This seems to be the setting that confuses people because it has a tech label. Lux is the SI unit of illuminance, equal to one lumen per square meter. Does that help consumers adjust this? What should the control be labeled? One could call it "Dusk Set Point" for example. What the control does is set the point at which the unit senses it is "dusk" and at that point the light will operate in motion detection mode (or D2D mode depending on the other switch) all night until it gets light outside. At the point it gets brighter than "dusk" the light will stop working until night comes again. The two extremes on the control are 0 (zero) Lux and infinite Lux. The closer to zero the control is set, the darker it will have to be before the unit trips "on" and operates all night. The closer it is to infinity, the brighter it will be when the unit starts to work. When I say operates all night I mean it will operate either in the D2D (dusk to dawn) mode (basically just "On") or Auto mode (motion detection mode). This depends on the four position switch.I hope this helps people. I have included pics and one of them shows the settings I am using for motion detection. As I said, it works just fine provided you read and understand the settings and how they interact. It's a shame that companies that make decent products take chances with poorly written instructions. If they would just explain things in a more natural way they would be a lot better off.

Great motion light I bought two for myself and bought one from my parents. Easy to install easy to angle to the correct position super bright.

Seems a good product

Right out of the box the wires were burnt.

Just installed this motion sensor light a few days ago. It's really bright, works well, and reaches out well past the area we intended it for. Built well and should last quite a while. Really easy to install.
