Think about what you're saying smarts; The best sales team in the world couldn't sell an elecrical prod. to an engineering firm w/o a UL approval stamp on it; one failure resulting in a fire would destroy the the engineering or architecural firm that specd. the product. The lawyers would have a field day. Now they have the UL stamp so, hang tough smarts, FWIW, I just bought some more. Hey maybe a Co. like GE will take an interest ??????
