Evaluation: The Lutron MS-OPS2 Occupancy Sensor Switch - The Silicon Underground

From GreatGameGuides


I installed a Lutron occupancy sensor switch this weekend. It detects you getting into the room, turns the lights on, then turns them off five minutes after it detects no person is within the room. The timeout interval is adjustable. It comes in 4 models: MS-OPS2-WH (white), -AL (almond), -LA (light almond), and -IV (ivory) and retails for $29. Installation was surprisingly simple-it took about 15 minutes, which is about how long it takes me to change a daily change, and in contrast to most models in its value range it works with trendy CFL and LED lighting, however I like to recommend some prep work forward of time. It solves an actual drawback. Most days once i come house, each light in the house is on. I know why. I have two younger boys who can’t attain the lights, so that they can’t turn them off and on themselves. But in addition to that, they’re demanding. My wife goes right down to the basement to get one thing, turns on the light or lights she wants, comes back upstairs, and can’t flip the lights off as a result of her fingers are full. The bathroom lights keep on more often than not because the boys can’t reach. I go back around and switch the lights off, but let’s face it. Even though I make a acutely aware effort to turn off lights, several unoccupied rooms in the home keep lit even when I’m residence. Lutron claims its switches can save you as much as $25 a 12 months. We’ll talk about that math in a bit. But there’s a caveat. Before you purchase one, double-verify your gentle switches. Most automatic switches require a ground connection, and it’s solely been in relatively current years that electrical codes have required floor wires on gentle switches. In older houses, you may discover there isn't a floor wire. If the sunshine swap is in a metallic box, the metallic field could also be grounded, but you can’t essentially assume that. If there’s no floor wire, use a different change. My dwelling dates to the early 1960s but has been renovated not less than twice. Some of my switches have the ground connection and some don’t. I have steel bins at a lot of my switches, which are imagined to be grounded. In some cases, I can see they are, but you can’t assume all steel boxes are grounded. At my rental house, constructed within the 1950s, some are and some aren’t. So test first, before you buy a bunch of switches, discover they won’t work for you, and must return them. The upside to the MS-OPS2, as opposed to many others prefer it, is that you simply only want the 2 wires that go into the swap, plus ground. Many related switches want the white neutral wires too, along with floor after all. Putting in is definitely a little bit bit easier than swapping a traditional change. Turn off the breaker box (very important), then take away the outdated change, straighten the wires, attach one wire from the old swap to one of the black wires on the Lutron with a wire nut, then attach the other wire from the previous change to the opposite black wire with a wire nut, then attach all of the naked ground wires in the field to the bare floor wire on the Lutron and the inexperienced wire. In some circumstances you may have a much bigger wire nut than the ones the Lutron consists of. You possibly can manually flip the change off and on using the large pushbutton. I put one in my basement, and it detects me from 15 feet away. It makes an audible click on when it turns on the lights, however the clicking sounds much like another light swap. The final regular switch I purchased is quieter than the Lutron, however it doesn’t hassle me. I put one other one in my L-shaped kitchen. If I can see the change, it sees me and turns on the light. Opening a door won’t journey the swap, as it makes use of an infrared sensor that a door won’t trip. You may regulate the default settings using directions included in the package. For instance, you may adjust the timeout to 20 minutes if you’re concerned in regards to the longevity of your CFL bulbs. You can even allow a daylight sensor, so it doesn’t mechanically flip the lights on if there’s already quite a lot of sunlight in the room. To determine what the Lutron could prevent, estimate what number of hours a specific light stays on. Calculate the wattage of the bulbs. Multiply those two numbers, then multiply by 365. Divide that quantity by $1,000 after which multiply that quantity by what you pay per kilowatt/hour of electricity. Ten or 11 cents is an effective estimate, if you happen to don’t know. 11. I get $14.45. With the Lutron, the bathroom lights would in all probability be on less than 2 hours per day. 11. I get $3.61, for a savings of $10.84 per year, which implies it could pay for itself in lower than three years. You’ll realize further financial savings from the elevated life expectancy of the bulbs and a slight decrease in your cooling prices in the course of the summer time months. If the life expectancy of the bulbs doubles or triples, $2 per yr is an inexpensive tough estimate. If you employ bigger bulbs than me, the payoff can be faster. And if you still have incandescent bulbs, the payoff could be much sooner. If your own home wiring permits you to put in these switches without a lot difficulty, they’re a great power-saving and high quality-of-life improve. The one factor you’ll need that doesn’t come within the bundle, moreover a screwdriver and needle-nostril pliers of course, is a GFI/decora-type plate the same measurement because the one it’s replacing. You can take a look at it as a great investment, too. I can’t think of many things-not to mention issues that cost lower than $30-that give me a 30% return on funding every year. The cost of bulbs will come down over time, of course, however the cost of electricity goes nowhere however up. I’ve executed quite a lot of different issues to help me save energy over the years. Most are pretty cheap. I installed thermal blinds and thermal curtains. Then I insulated my electrical shops and added little one safety plates. Of course I use LED bulbs. I additionally insulated my scorching water pipes.
