Technology Sourcing And China

China is without doubt a source of product that is hard to avoid. It’s doubtful that today’s technology is built without some components sourced from China. HiLumz USA is no exception. However, we purchase as few components made in China as practical. When we do purchase them, all efforts are made to purchase from US companies with operations in China, and not China engineered and produced components.

Our highly regarded Diamonz and HyperNova LED boards are fabricated and tested in USA ISO 9001 certified SMT facilities. Our engineers are American professionals with years of experience in LED circuit design. As an approved CREE branding partner, the Diamonz LED retrofit “engine” must pass the stringent standards of CREE’s TEMPO test program.
