Beat those winter blues with this compact supplementary daylight system. Suitable for the treatment of Seasonal Affective Disorder (SAD). Uses a mini CCFT (cold cathode florescent tube) lamp for daylight simulation with a blue light spectrum. Small and portable for use anywhere a mains plug is available. Much more convenient than large tube units and better than LED versions as it does not create "spotting" in the eyes. Supplied with a digital switching power supply for worldwide use.
