Red Light Irradiation was a word that was used on a daily basis in the GDR.

Through the intervening fortnight he ran about and smiled outwardly at his inward thoughts, as if they were people meeting and nodding to him—smiled with that singularly beautiful irradiation which is seen to spread on young faces at the inception of some glorious idea, as if a supernatural lamp were held inside their transparent natures, giving rise to the flattering fancy that heaven lies about them then.
