SemiLEDs has made improvement on its EV- family of LED chips, enabling a 10% increase in blue chip brightness and 8% decrease in forward voltage (Vf) during mass production. With this achievement, its clients are able to reach over 130 lm/W with cool white and 110 lm/W with warm white measuring at 350 mA.

With Enhanced Vertical (EV) technology, SemiLEDs was able to increase brightness and lower defects with its new advancements in Epitaxial and Process Technology. Production monitoring showed an increase of 10% in the brightness distribution and improved leakage current yield. The EV technology not only increased the luminous output, but it also enabled a down shift of Vf distribution by 8%, increasing the efficiency by 6~8% at 350mA.
