The light alarm clock simulates natural light from sunrise to facilitate awakening, to make it more "comfortable". A wide range is available through 10 settings to choose from. According to taste, or need, everyone will have the necessary and sufficient amount of light power to promote its revival. Progressivity is welcome and proves very satisfactory to use. Furthermore it is possible to choose a sound, unfortunately only two are available to complete enlightenment. Radio is there to take over when the two sounds are insufficient or become unbearable! Note that the reception is good and the sound, fair, is entirely in the standards of this type of product. A friendly product.
