Up to 300 lux light intensity for both natural awakening and easy reading
Philips HF3490 Wake-Up Light offers up to 300 lux light intensity. The sensitivity to light differs a lot from person to person. In general, when using a higher light intensity a person needs less time to become fully awake. It has been clinically proven that you need up to 300 lux to affect energy hormones in such a way that you wake up full of energy. The light intensity of the Wake-Up Light can be set up to 300 lux. This makes sure you can wake up to the light intensity that suits your personal preference best.

A bit sceptical when I first received it but it works. The light really does wake you up and you can set many degrees of brightness. Read morePublished on 31 Jan. 2011 by Adrian A. Ambroz
