An EU funded project, named ENABLED, is working on creating LEDs with artificial fluorescent proteins to make the lighting source more sustainable. Currently, LED lamps consist of a blue-emitting chip and an optical filter made of inorganic phosphors, rare earth minerals that transforms blue light into the white light. This filter does not efficiently convert blue light, causing serious implications on visual acuity in children and sleep disorder in adults. Moreover, inorganic phosphors are quite scarce and are listed as one of the 27 critical raw materials by the Euro...
