We have a large dark porch (see attached image) where it was not possible to install a motion sensor due to the brick and stone wall construction, foam insulation and limited access to the existing circuit breaker wiring. . These Awanber-US motion sensor LED bulbs replaced our regular 65W PAR38 recessed bulbs and solved our dilemma! Although we've only had them for a few days, they work exactly as advertised! A NOTICE. You must purchase a DiCUNO E26 1" Flex Base Extension Adapter, E26 to E26 Edison Screw Converter Lamp Base Extender Lamp Socket Adapter (2pcs) [4 3/8" Length, $8.99 per Revain] as these bulbs are the same width like the hole in a normal built-in glass and therefore does not fit in.
