Hah! Love this piece. I live in a rural setting in Co.Wexford, Ireland. I have no curtains on my windows as we are not overlooked. So; I wake up to natural light every morning*. No need for a Wake Up Light. I can imagine if you live in a city and / or use blackout curtains this Light would be a very good idea.
*…and birdsong and the sound of a burbling river. With a little light traffic in the distance. Yes ; idyllic!
