These have been especially good during the winter months with it getting dark quite so early - my dog has a huge enclosure / kennel outside whilst i'm at work and I had wanted a light coming on for her so she wasn't sat in the dark for 2 hours before i get home. Great product and saved me having to go and buy a couple of new PIR lights for the garden after the sensors all seem to have died. Please make sure there are not incandescent or halogen luminaries at close quarters as that includes wavelength similar to daylight and may interfere the sensors. For best performance, Please don't cover or block the sensors or use in fixtures included photocell or other additional circuit. Cut off power before replacing,And just leave the light switch on as the bulb will turns ON/OFF by its own when senses triggered.
The sensors only response to the infrared spectrum from 860～1100nm which was included in sunlight, The wavelength range from LED Lights are from 380～780nm, That means the bulb doesn't response to other nomral LED lights in order to provent the light interference.Detects Sunlight Only, No Response to Lamplight.SINCELIGHT DUSK TO DAWM LED Sensor Light Bulb(V2.0), Equipped with dual ingenious daylight sensors,It turns ON at Dusk and OFF at Dawm by its own, More comfortable lighting experience at LOW COST.To learn more about how and for what purposes Amazon uses personal information (such as Amazon Store order history), please visit our Privacy Notice.
