Just this morning I splashed out a not so insignificant amount of money on what would be termed a'luxury good'. In other words, it was not the usual food, heating or clothing purchase. I am quite proud to say that it is not often that my wife or I spend money on non-essential items. So what was this item that caused me to part with my cash?rnWell it was the'Philips Wake Up Light'. Yes, this alarm clock with a400 lux light bulb is intended to combat Seasonal Affective Disorder(S AD) and WinterBlues.lt isessen-tially a wake-up light bulb with natural daylight spectrum and friendly wake-up sounds and beep. In fact you can set it to 3 natural sounds (morning birds, seashore, pond) or your favorite digital FM radio station. Now why would I share such an anecdote here in this top rate academic publication? Well the clue may be in the manufacturers of this product ....Philips.
