The invention application deals with the LED light having at least two simply switchable lighting modes. The first mode quite eliminates the blue wavelength light which is harmful to human organism at night. It's recommended to always turn this light on after nine in the evening and use it until the sunrise. The second mode already has a low blue wavelength content, being suitable during afternoon hours and relaxation. The third mode already represents the daily sunlight with a high CRI value and should be used during day only. The mode switching is set in a way that after turning the light off and then on again, the first mode with monochromatic red colour will light first, thus the circadian rhythms are not affected at each wakeup and turning on the light.
