But the operators lack the concepts of R & D and design, and most of the products are copied from the ideas of others. Given the international trend of protecting intellectual property rights, this has naturally been criticized. Moreover, the important parts, like electricity-saving lightbulbs, are all in the hands of Japanese companies. Thus Taiwan's lighting industry has long been stuck at low-profit, low-end products.
然而業者沒有研發設計的概念、產品都是東抄西湊仿冒而來，在保護智慧財產權的國際潮流下勢必受人抨擊；而且重要的元件如省電燈泡等，也都掌握在日商手中，因此台灣燈具一直停留在利益菲薄的中低級產品層次。
