Soraa, dedicated in developing GaN solid-state lighting technology, has been selected by Advanced Research Projects Agency-Energy (ARPA-E) to lead a project on bulk GaN substrates development. It’s the only ARPA-E funded LED substrate project. Soraa claims to be the only LED manufacturer in the world shipping products based on superior GaN on GaN LEDs. GaN on GaN LEDs are of particular interest because they have demonstrated much higher performance than traditional lighting technologies and thus offer the potential for major energy savings. ...

In July 2012, Seoul Semiconductor (SSC) announces a new LED product called “nPola,” which takes SSC more than ten years to develop. The product features the non-polar technology that increases brightness levels 5 times over existing LEDs. Currently most mass-produced LEDs’ luminous efficacies are around 100lm, but SSC’s nPola product’s luminous efficacy reaching 500lm, five times higher. Simply put, a 60W equivalent LED light bulb usually requires 10-20 LEDs, but it only needs 1-2 LEDs if adopting nPola product. According t...
