  • A very useful thing

    posted by Galich27

    I once bought a set of 3, saved $ 3 - the price turned out 6.52 per share. All three regularly work for 4 months. One of the lamps I stuck to the ceiling on the tape that was attached to the kit. After 1 minute, lantern blade and crashed, but nonetheless remained operational. In another Phanar broken switch "Off - auto" - he remained in the position of "auto" and after 4 months of care "
    Necessary thing in the economy .
    I am pleased with the purchase .
  • Good item

    PriceEasy to installGood reception of movementCan be build into custom housing
    Missleading information about light timeout. But can be adjusted if you are skilled with soldering gun. (see forum below)Default delay of this sensor is aprox. 40 seconds.
    Good item for this price.I'm using it as light switch for my hallway and I'm very satisfied. I managed to build it into ceiling and sensor is almost invisible and nicely fit into ceiling.
  • Better Than Expected

    posted by rcarlyle

    It just works and works very effectively
    To be frank, I wasn't expecting much, so when I opened the door and found the light on, I expected that it just stayed on, but I was wrong. After leaving it alone for a couple of minutes, it turned off and was so sensitive that it actually switched on as I opened the door and also from the bottom of the stairs.
    Excellent product which makes me think that I should purchase a couple more.
  • Light sensors works great; easy installation

    posted by cosmicray

    The device easily detects motions in its working range. The schematics on the device is very useful, though there is no instruction in English.
    Manufacturer would do a great job if the back of the device was covered by an insulating material.Also, there is no way to attach the device to the wall of ceiling. I managed to do it on the plastic ceiling by attaching it to a special bulb socket that was lacking a bulb.
    Although it's not perfect I highly recommend it to anyone, because it's very useful.
  • Works fine, no adjustment pot

    posted by ed2096

    Works as advertisedVery wide detection angle (120)Cover pops off if you don't want it5A relay useful for driving things like LED stripsSeparate wire for PIR sensor makes it more flexible
    Will stay on as long as there is movementNo protection against flipping on/off constantly (e.g. minimum off period)Consider another model that has an adjustment pot if you need itOnly tested relay using 12V source
    Cheap, worth buying if you can deal with minor limitations, easier than building your own
