sams club lights here and loving them .
also the newer units are likable up to 10 per circuit and 3 way power low/med/high output by the pull cord .
no cold start problems in a non heated shop in the winter .
no hum of a ballast box
just a good bang for the buck .
going to sound crazy but my 1800 sq ft shop i like light and no real shadows . . . . i have 30 in the main shop and 6 in the paint bay .
all doing good no problems on most now over 2 years .
