However, LEDs with higher indium concentrations, such as red and amber LEDs, suffer from a drop in efficiency with the increasing amount of indium. Currently, red and amber LEDs are made using aluminum indium gallium phosphide (AlInGaP) instead of InGaN due to InGaN's poor performance in the red and amber spectrum caused by the efficiency drop.
