Question: Will these work on a 220v 50hz outlet?
Document: I had read through the reviews before purchasing. I still decided to purchase these lights because they appeared to offer all of the features I needed. I could find nothing else like it. I have to say that I am glad I did. My experience with these lights has been excellent. Unlike the Maxxima MLN-50 (non-motion sensing version), this model does not, in any way, inhibit the use of the lower outlet when plugged into the top outlet. It is bright, very bright.
The AC powered motion activated led lights work well. They replaced some similar battery operated lights. I would recommend them.
These worked very well, I use them in the kitchen at night, so I don't bother everyone in my small house with electric overhead lights which are too bright. They are on for just enough time, and work instantly when within range. Love em
If you are looking for a very bright LED night light that consumes very little electricity (0.8 watts) and will automatically turn on when you are in the room and turn off when you are not, than buy these!!! They work exactly as I expected them to and wanted them to. I HIGHLY recommend these night lights!! !
These work perfectly and have been a great addition to home safety. I put one in my bedroom to avoid stubbed toes on late night excursions to the loo, and the other halfway up a dark stairwell. They put out a lot of light when it's pitch black. No more stumbling around in the dark.
These do work well, but the motion detection part relies on your being square-on to the sensor. With these plugged into the outlets on the side of the staircase, you can creep up to within a couple of feet before they detect that someone is there.Coming out of a room, square-on, and they work quite well indeed with more than enough light to allow for safe passage.
This simple mod made it work perfectly in our bedroom.The light is a very bright, yet unobtrusive, soft blu-ish white. It remains on for about 1 minute, then resets and turns off. As long as the dusk-to-dawn sensors receives enough light during the day - the night light does not trigger on with motion during daylight hours at all. I'm very impressed.
These two lights work beautifully in our house. It is bright enough for when its night time. I can now walk from our room to the kitchen without turning any lights on. Thinking about buying another pair just because they work so well. It detects from about 10-15 feet away easily as long as nothing is blocking its path. Overall very impressed with this purchase.
Recommended. Quality product. I ordered the 2-pack to test these before buying a number of new night lights. This is my preferred product for most applications. It is motion activated, ant that feature does work, and works well. For a couple of applications, like at top of stairs, I ordered the Maxxima model that is only light sensing, so that it is on constantly when room is dark, without motion sensing. Very pleased with product thus far and have ordered more.
Works as advertised. Detects my presence upon entering a darkened room. I still would prefer the brighter light given off by an incandescent bulb but this light is up to the job.
