MOTION SENSOR BULB SCREW TYPE
I have had two of these units and both failed within a short period.
I recommend reading the low star reviews before purchasing.
I wanted to turn the lights on/off automatically in my mother's hall at night, but to not operate during daylight.
Both the units I ordered were received quickly and worked perfectly when received. I would have given the product and AV10 5* as others have done at this time.
But be warned. My first unit failed completely in less than six months. I returned it to Amazon who paid the postage and reimbursed the product cost. Good customer service.
I ordered a replacement, this was shipped from AV10. Again the light worked well when received, but failed completely in less than 3 months.
I returned the unit, deciding not to replace as I feel there is either a quality problem with the product or batch of them. I notified AV10 of the problems I had experienced with the product. They agreed to re-imburse the product cost, but would not pay for the return of the faulty unit. They quoted their returns policy and would not budge, despite being asked by Amazon to pay for the postage as the unit failed.
Reading the reviews I see many others have experienced the same problem.
If you feel you want to take the risk with this product, buy it from Amazon directly.
