|This sealed beam is 12-13 volt, 100 watts and is 4 1/2" in Diameter.|
Well see how long they last, but their useful life is longer than the non-quartz lights I was using, and they seem to be much brighter as well. Exact fit for my 172.
Quartz unit much better than original, arrived on time an not broken....
I installed the landing light and it works great. The first light came through broken in transit. Aircraft Spruce immediately replaced it with another light. VERY PLEASED with customer service!
