A key breakthrough has been the use of laterally injected quantum wells via naturally occurring V-defects which promote hole injection through semipolar sidewalls and help to overcome the barriers to carrier injection that plague long wavelength nitride LEDs. In this article, we study V-defect engineered LEDs on (0001) patterned sapphire substrates (PSS) and GaN on (111) Si. V-defects were formed using a 40-period InGaN\/GaN superlattice and we report a packaged external quantum efficiency (EQE) of 6.5% for standard 0.1 mm\n                    <jats:sup>2<\/jats:sup>\n                    .
