SINOWIN’s SMD high voltage series include 2835 high voltage series, High CRI(Ra 98), low Color Tolerance Adjustment(<3.5SDCM), which using pure gold wire, copper submount as raw material to achieve good heat dissipation, high brightness, low lumens depreciation. We use international authority standards: such as America's Energy Star and European ERP (Macadam Elliptical System). All of products had passed SGS-RoHS, LM-80-08, and 300 times of cold-heat thermal shock tests.
