Outdoor Motion Sensor Light Durability
Yes if you buy no name china with no UL listing you will be changing the fixtures out regularly.
I would suggest LED and to assure long life you want a fixture that is DLC and UL certified UL underwriters laboratory, Design Light Consortium requires a 5 year warranty.
I purchase a large number of fixtures and lamps Every year and find good prices and the above 2 certifications in many products they sell.
Check our LEDMYPlace.com and 1000bulbs.com
I have no connection to either company other than having purchased at least 100 from each and the very few problems I have had are quickly taken care of.
But in any case the DLC certification in a lamp or fixture has provided long life in rough environments where non DLC from other parts of the world have had many failures in fact not many have lasted beyond their warranty.
