Lights of America products are, ironically, made in China using mostly
Japanese fluorescent tubes. They're also well known to make some of the
worst quality lighting products in existence. You get lucky once in a
while,
but I only have two LOA products that still function, one is an early
1980s
circline retrofit with a magnetic choke ballast in the rarely used storage
closet light, and the other is fluorescent wall pack out back.

CU has reported that LOA CFLs have relatively short lives.
