The typical range consists of AC and DC-driven units with luminous efficacy exceeding 100 lm/W.

China's mainstream high-voltage LEDs in AC and DC-driven models have rated voltage of more than 20VDC or 220VAC. These have over 100 lm/W luminous efficacy and above 90 percent efficiency. CCT is 3,000 to 6,000K.

The products use PCT package material for its better feature set than PPA and comparable performance with EMC. The input has ceramic fiber, ensuring low saturation, and resistance to UV and elevated temperatures.

Shenzhen Kinglight uses PCT in its high-voltage SMD units not only to bring down cost but also to achieve greater heat dissipation and efficiency. The company predicts the material will be the popular option in the future.

The majority of suppliers ensure products comply with RoHS guidelines.

They source manufacturing inputs locally. LED chips, however, come mainly from Taiwan and US providers.

The supply and the cost of materials and components, which also include PCBs and adhesives, remain stable and will keep prices at current levels until year-end.

Some manufacturers will reduce rates, anticipating competition from new entrants. The adjustment will be less than 5 percent.

Here is a selection of high-voltage LEDs from China:
