Shortly thereafter, a group of Christians, under Peter the magistrate, went looking for Hypatia, the "pagan woman who had beguiled the people of the city and the prefect through her enchantments". They found her sitting in a chair, at which point they seized and brought her to "the great church, named Caesarion", where they proceeded to rip the clothes off her body. Then they dragged her through the streets of Alexandria until she died and burned her remains. John's description of Hypatia's death also differs from that of Socrates. Following the death of Hypatia, Bishop Cyril was named "the new Theophilus". With the death of Hypatia, John writes, the Christians had expelled the last remnant of pagan idolatry.
LEDs using the color-mixing principle can emit a wide range of colors by changing the proportions of light generated in each primary color. This allows full color mixing in lamps with LEDs of different colors.  Unlike other lighting technologies, LED emission tends to be directional (or at least Lambertian ), which can be either advantageous or disadvantageous, depending on requirements. For applications where non-directional light is required, either a diffuser is used, or multiple individual LED emitters are used to emit in different directions.
