O God of Light was written by Fr. James Quinn S.J. (1919-2010) and was first published in New Hymns for All Seasons (1969). The text is set to the traditional English melody, Danby also used for the setting of 'Tis Winter Now, the Fallen Snow (1906) by Samual Longfellow. The first video features a choral arrangement of 'Tis Winter Now, and the second has Father Quinn's words set to Puer Nobis (thanks to reader for comment below for helping identify tune). In the Liturgy of the Hours, O God of Light is used during Ordinary Time for Morning Prayer.
Tune: Puer Nobis
