Macarrie 20 Pieces Dusk to Dawn Sensor for Outdoor Lighting 100-277v Photoelectric Switch Bulk Photocell Light Sensor Photocell for Outdoor Lighting for Most Outdoor Lighting Fixtures

Bought and installed 50+ of these. Easy install. No DOA or premature failures. These were mounted on top of wall packs and we used a little silicon sealant to insure they were leak free.

These photo eyes are junk. i purchased a 20 pack.I installed 2 units on brand new light fixtures,My customer called the next day to tell me the lights did not turn on at night.i sent one of my electricians out to troubleshoot and found that the photo eyes were not working.I then checked a few of the new ones still in the box and they also do not work .

Amazing quality loved it

10 out of 20 worked if you tap the sensor, still afraid of using them don't need that many service calls. I need to find a more reliable product.

Ordered 20 set up 5 non of them worked.Electrician spent so much time testing non of them worked.Can't returnWaste of money and time.Please do better with this product.

I have ordered these before. The last 2 times, the percentage of malfunctioning increased to the last order, 17 did not work. We are nolonger buying these items from this distributer.
