Motion Sensor and LED Dimmer Switch, Single Pole/3-Way | Auto On/Auto Off sensor for bathroom, for dimmable LEDs delay off timer, Title 24 compliant, MSCL-OP153M-BL, Black

When i replaced all my floodlights with led bulbs, I also replaced my manual dimmers with these. They work great and can be programmed as to which intensity to turn on at, they also learn how low the ambient light needs to be in order to turn on (Depending on the setting). Also, there is an advances setting mode, found that in a separate manual. That allows you to lock the switch at a given preset, so even if you change the light level, after turning off and on, you're back to the preset level. This is useful for example in a hallway by the bedrooms were i set the preset at the lowest level so we don't get blasted by light at night. So, while the positives are obvious from a quick look at the manual, here are a couple gotchas: - These dimmers work in a three way setup, but only with a companion dimmer that does not have a sensor. So if you want a motion sensor at the base of your stairs and a motion sensor at the top of your stairs, this will not work, kind of a shame. At least with the companion dimmer you can control dimming from both ends of the stairwell and turn the light on/off with the button - You can use this in a three way setup with a regular siwtch (just have to change a setting so it knows you're using a regular switch) - the motion sensitivity setting only has high and low - basically, high is not high enough and low is not low enough. Wish it would have a broader adjustment range My only major issue with these switches is that I have not found out a way to force these to stay on - basically without any movement, the light will go off after the timeout. Yes, you can go in the settings, follow some steps, and disable the motion sensor but that pretty much defeats the purpose of buying a dimmer with a motion sensor. I wish that i could hold the up button and turn the light on and then it would stay on until i press the button. About the same goes for off. If you want the light to stay off while you're in the room, you can pull the bottom service switch, but that's hokey.The way the sensor works is, after you turn off the light, it waits for the movement to stop and then 20 more seconds. but if you're sitting still for 30 seconds, then your next motion will turn on the light. Most other motion activated switches have a manual switch, that would have been an option too. So, while the ability to force the switch to stay on would have been nice, we really like the switches overall. They work very well and we have them all over our house.

This was a great purchase! We were looking for a motion sensor dimmer for our bathroom, lighting in our guest bathrooms and also the bathrooms of our children and this works great! We have set it and told everyone to forget it! When you walk in the light comes on and when you leave shortly after the light goes off! Easily cleaned is black and color and looks sleek!

Been using Lutron for years. These are great and look awesome. Easy to use and no flickering with LED bulbs.

I purchased this for use in our kitchen's breakfast nook to allow adjusting the brightness and for shutting off the lines when everybody had left the table. Installation was fairly straightforward and it took all of 30 minutes to swap the switch and configure it to my liking. The only thing that stumped me for a moment was the green ground wire coming off the frame, and what I thought was also a green ground screw. A quick consult of the directions declared that the screw was actually blue (still looks more green to me) and it was only needed if wiring with multiple switches. I see folks complaining that their LED's flicker with this switch. They need to make sure that the LEDs are actually dimmable. While the switch works with LEDs, the bulbs ALSO have to be dimmable. If the bulb drivers are not designed to be dimmable they will flicker. I also see folks complaining that it is hard to configure. There are four settings you can set, each with no more than four choices to select with each. You only have to set the ones you want to change from the defaults. For those on the West Coast, this switch meets California Title 24 building requirements that now require vacancy sensors to control lights in bathrooms, garages, laundry rooms, and utility rooms.

Very capable motion sensing dimmer switch, with a craftsmanship that reflects well on the Lutron brand. The instructions are clear and there is more in-depth documentation to be found online -- search for 048480a.pdf on Lutron site as someone else pointed out, or simply Google it. The product also has one of the highest levels of customization I have ever seen in a motion sensor switch. Lastly but not something to be glossed over, the switch makes absolutely no sound when it turns ON, which is indeed refreshing seeing as how nearly all regular, non-dimmer switches make an audible 'click' sound when the motion sensor gets triggered. Plenty of other reviews will serve as a primer to delve into the features and customization settings this product offers, so I will gloss over them for the most part. Installed as a single-pole switch in a bathroom vanity, which controls a total of 6 dimmable LED lights. Thankfully the lights did not "flicker or strobe" unexpectedly at the high- and lower-end brightness settings, so I didn't need to go into the advanced setup mode to update those levels at all. The switch in this case is facing the direction of the person entering the room, and turns on immediately (and silently) due to the 180° coverage area. All is well, but due to my use-case I did have to make a few adjustments from the default values: * Timeout set to the minimum allowable value of 1 MINUTE, which is how long it waits to turn OFF after detecting no motion * Occupied level set to PRESET (led position 1), so it automatically turns ON to the last manually set brightness level * Nightlight Mode disabled and set to OFF, just to conserve a bit of energy and due to the fact that usually there is no need to manually turn the lights ON, since it automatically does this each time. I also do have the Ambient Light Detection (ALD) disabled, since the room is always dark and I want the sensor to always trigger. One small gripe in regards to the timeout setting: minimum is 1 minute, but I wish 30 seconds was a configurable option (call me vain or perhaps not rational, but I however was curious to see if such a low timeout setting would be feasible at all). Further, while the value set is 1 minute, I have consistently noticed after observation that the lights do turn off a couple seconds past the set timeout -- they seem to fade out approximately 1 minute 15 seconds after vacating the room. I wasn't able to figure out the cause of the delay in the timeout, but it seems internally preset and no way to update that at all. The automatic FADE IN of the lights seem to happen too fast for the human eye to appreciate it - but this might be due to the brand of LED bulbs I have or due to the level I have preset. Currently my preset level is at 50% brightness, and I notice the lights automatically turn ON in <1 second when any motion is detected. In contrast, the lights take about 5 seconds to automatically FADE OUT after no motion is detected. I certainly wish that the automatic FADE IN/OUT values were able to be customized, but these values seem to be internally set which is unfortunate. Lastly, I've listed the Pro's and Con's of this product below. Overall a fantastic product with a few shortcomings that I have noticed. + Solid, in-depth documentation + Lots of customization options available + Completely silent when light is turned ON (no sound of relay being switched) + Manual ON/OFF is also possible + Indicator LEDs show the current brightness level + Able to set high- and low- end brightness "trims" in order to avoid a flickering/strobing effect on some bulbs - Can only set the manual FADE IN/OUT for the switch; unable to set these values for when switch *automatically* turns on - Cannot set a timeout < 1 minute - Hidden delay of 15 seconds or so in addition to set timeout

Item works great with dimming 6 led ceiling lights. It does not cause any odd flickering. Smooth transitions from bright to dim. It is programmable for time duration of motion sensor and brightness when it comes on when triggered by the sensor. The options are great, especially if you use it to automatically turn on a light when you walk in a room but don’t want full 100% brightness. Programming it is a bit of a pain, and not intuitive. But once it’s done it’s set. Directions for programming require internet access, it only has a QR code to take your I the instructions.

Paired with five Kobi 1100 lumens and two Kobi 1500 lumens. Worked out terrific, super impressed. Super pleased with the Kobi bulbs, both the sets of 5500K and 2700K, better light spread than the florescent they replaced (actually a perfect light spread, could not imagine any bulb being better) and I have to put my ear right up to the bulb in order to hear any buzzing. I don’t think I would ever risk buying any other brand in the future because I’m so happy with these. A few tips, (1) Buying slightly higher lumens/watts with a dimmer that can be set to always turn back on to the place you left it was brilliant. We turn up the lights brighter when the kids are at play/doing art, when I’m working on something, but then the other 90% of the time they are set slightly under the max capability. (2) Auto sensing dimmer was super, no reason to yell about the lights being left on, and no need to go to the switch when you enter the room. Be sure your automatic dimmer senses when you enter a room, many on the market have to be turned on manually and just turn off when you leave. Often the terms occupancy switch vs. vacancy switch can indicate the difference. (3) When it comes to the bulbs, don’t buy too cool. I thought the pure sunlight like temperature of 5500 kelvin would be great for our space, since the kids play there a lot, do art etc. This didn’t work out. Everyone felt it was too cold and enjoyed the space less. Amazon’s return on these was super simple (I’m Prime, not sure if that made it so simple), and we purchased the Kobi 2700 kelvin bulbs to replace these. I thought they were going to be too warm and had wanted to find something in the 3500 kelvin range, but they were not. They are just perfect!

This Lutron MSCL-OP153M motion sensor dimmer costs more than others, but if you are sensitive about your home environment, it may well be worth it to you. I have installed 3 of these in my home during the past few years, and am very pleased with them. I was on the verge of purchasing a fourth switch when amazon offered me a free one as part of the vine program, in exchange for writing a review - an offer I just couldn’t resist. If your light switch is in a favorable location, you can replace it with a motion sensor and the lights will turn on automatically when you walk into the room. Very handy in places like garages, laundry rooms, workshops - basically any room you tend to enter with your hands full. The most obvious thing setting these Lutron Maestro sensors apart, is the pleasant, soothing, fade-to-on and fade-to-off effect. When we come home at night, our hall lights smoothly fade to on as we walk through the front door. We no longer need a constantly burning night-light in the bathroom: as a guest enters the room the lights gracefully fade-on, and then turn themselves off just as gracefully a few minutes after the room is vacated. Other, less expensive occupancy sensors can do a similar job, but the big downside is they snap on, and snap off abruptly. They are a good choice if you are on a tight budget, or if your lights cannot be dimmed (most fluorescent tubes cannot). There are many brands of this harsh style switch, including Lutron (I installed one in my mothers laundry room with non-dimmable fluorescent lights and it works fine). But don’t kid yourself, the experience of this abrupt on-off style switch is far inferior compared to the Maestro dimming sensor. In most applications, I would probably re-lamp the room with bulbs that dim in order to use the Maestro. The Good: Clear, comprehensive instructions come with the switch, detailing the most common installations. Plus you can look up additional details online for special cases. The wiring job is easy, and straight-forward IF you are replacing a single-switch-controlled light. Just wire it in exactly like the switch you are replacing and it will work fine. Can be wired into situations where more two switches control a single light (curiously called a “three way” configuration in the electrical trades). This situation is a bit tricky so you will need to follow the instructions carefully, but it can be done (if I can do it, probably you can too!). This extra complexity isn’t really a knock against Lutron, because even regular, mechanical 3-way switches can be a challenge to many DIY folks, especially those who don’t like to follow instructions. Lutron also makes a companion control that simplifies the 3-way situation, but I have no experience with that. Configurable in numerous ways to suit your taste, or the situation. The switch can function as an occupancy sensor (lights go on when you enter a room, and off when you leave, automatically), a vacancy sensor (you manually turn on the lights, and they go off automatically when you leave the room), and in many other ways. (More details about this below). Completely silent when turning on and off. Less expensive, non-dimming sensors usually use relays - if you have sensitive ears you will hear them click on and off. Lights can be set to any level. The dimmer part of this sensor consists of Lutron’s highly regarded Maestro dimmer. See reviews of that particular product for complete details. These switches are available in multiple colors (I have a Burgundy colored one in my wine-room, for example). These are thoughtfully-designed, sophisticated, well made switches - typical of the Lutron brand. I have numerous Lutron switches - some more than 10 years old - and cannot recall encountering a single defective one. The switch gives you ample warning that it is about to turn off the lights by dimming them many seconds before things go dark. This is a wonderful, useful feature - something cheaper, on-off style sensors simply cannot do. The Bad: Your existing switch must be in a “favorable” location. Basically the switch needs to be able to “see” you in order to work it’s magic. (More details available in Lutron’s online document.) These switches are a bit bulkier than simple mechanical switches. Not a problem in most cases, and no bulkier than regular dimmer switches, but maybe an issue if you’ve got a really small, tight, overcrowded electrical box. Summary: Any light that can be dimmed can be automatically and gracefully turned on and off by this sensor switch, as long as it can “see” you in the room. It will work with most bulbs that are dimmable, (including LEDs, Halogens, etc.) If your bulbs cannot be dimmed, this switch will not work - consider re-lamping with appropriate bulbs, or use an on-off style sensor (e.g. Lutron’s MS-OPS2). Other Details: What is a favorable location? A switch located inside the room, next to the doorway is often a very good location. Many switches in bathrooms, laundry rooms, and garages are oriented this way. A less favorable location is a switch that sees too much. For example I have a hallway light switch that sees into another room. It was a challenge to set up because it would turn on when one walked from the kitchen to the living room. I was able to get it working quite nicely by partially covering the sensor with a small piece of tape (basically “blinding its view to the left”). Configurability. Wow. There are so many ways to configure this switch I will cover only a few of the cool things you can do: Turn lights on when a person enters the room, and off a short time after everyone has left the room. This is often called an Occupancy Sensor. Do NOT turn lights on automatically - only do it if the On button is tapped (like a regular switch). But, once everyone leaves the room turn the lights off automatically. This is often called a Vacancy Sensor. Never automatically turn the lights on during the day - only do it when the room is dark (uses an ambient light sensor for this trick). Turn lights on automatically when someone enters the room. If that someone turns the lights off, don’t turn on again automatically until everyone has left the room. You might use this in your TV room. Set the highest and lowest levels the dimmer can be adjusted to. (Useful for certain finicky LED bulbs that don’t dim all the way down, for example). Adjust the level the lights go to when the switch automatically turns on (default is 100%). Adjust the rate at which the lights fade on and off. Disable the small, discrete, indicator lights on the switch (not even I am fussy enough to have tried this one - yet!) Set timeout duration to (1, 3, 5, 15 or 30 minutes). This is how long lights stay on after the room is vacated. Default is 5 minutes. Adjust the sensitivity of the main sensor (high or low). If this isn’t enough, you can cover part of the sensor with tape, as I did for my hallway switch. For additional details about this switch, goto the Lutron website (lutron.com), and search for the document entitled: 048480a.pdf. This 23 page document provides a wealth of information about the sensor range, settings, and myriad configuration options. Buy the way. If you really must know, my latest Lutron switch is going to automatically control the lights in our walk-in closet. Hope you found this review useful.

I quickly and easily installed this Dimmer Switch in the bathroom, wishing to set a new automatically-dimmed light level for a new very-over-bright LED vanity light. I love the fact that I could adjust the default settings to my preferences (see photo for details, it's a bit tricky). Now, as I begin to enter the doorway, the PIR motion sensor immediately recognizes the movement and quickly ramps up the brightness to my preferred, roughly-50%, level. Perfect ! The light remains on as long as motion continues to be detected. After my preferred setting of 3 minutes without motion, the light level is ramped down to zero. If a different brightness level is desired for a specific task, merely press toggle buttons. I was a bit confused at first, but after noting that if you elect to, or accidentally, manually press the switch to turn the light Off, the auto-on feature will be disabled for 25 seconds, even if motion is detected. This is to provide occupants time to exit larger rooms after manually turning the lights off. If immediately re-entering the room (within 25 seconds), the unit must be manually turned on. After 25 seconds, the unit will return to normal detection operation.

We had a 3 way light in our hallway in a dark part of the house where the switches weren't in the easiest spots to access. I swapped out the central one with this motion activated dimmer switch as we have a baby on the way and thought this would make it easier to turn on the lights in the middle of the night while ensuring it could be dimmed instead of full brightness. If you've swapped out light switches before, this one is easy enough and the only trick was that with the 3 way, I needed the other one in the ON position for this one to be active. It's easy to program using the instruction manual, and the motion detection works extremely well (catches you coming around the hallway corner or out of rooms and turns on as you are entering the hallway). We've set it to turn on to the last used brightness, so before bed I turn it to a dimmer setting and in the morning keep it closer to full brightness. Very useful and works so well that I wish I'd installed it a year ago when I first thought about it!

I have a couple of the Vacancy versions of this sensor, and I just bought one of the occupancy versions. Carefully review the specs so you buy the right one. The occupancy sensor (OP) turns on automatically when you enter the room and turns off 5 minutes after you leave. It also has the dimmer which has about 8 discrete settings. All these things are adjustable, including the sensitivity. I installed this on a circuit of 8 LED lamps in my garage. The idea is it replaces the crappy light on the garage door opener which turns on whenever the car enters the garage. So far it is working beautifully. When you select one of these be sure to calculate your overall power usage. These babies get hot if you run them with more power than they are rated for. Further, if you put more than one in a box, the limit goes down. This is due to how much heat they create . The switch itself is quite large so you can't stuff any wires in behind it unless you have an extra deep box. Its a good switch at a good price. I recommend. Just do your homework.

The motion detection is too good, sometime you would wish it wouldn’t be! Area of covarage is huge! It is annoying that it doesn’t have a manual on/off function or always on/always off

This motion switch works extremely well. After purchasing several other products, the issue I kept encountering was that LED bulbs would remain dimly lit despite the switch being in the off mode despite trying a number of popular dimmable brands. The reason for this issue, any motion switch that doesn't require a neutral wire relies on remaining energized for its internal components to work which often results in a minimal amount of power continuing to flow to the LED bulb. As I now understand it, switches that use a connection to the neutral wire are able to keep themselves powered while completely disconnecting the bulb from power. Hope this helps others avoid the frustrations I've encountered!
