These lights provide summer levels of bright light all year round, to lift your mood, boost concentration and restore your natural energy. Sunlight is a natural mood-booster, influencing body chemistry (e.g. melatonin and serotonin levels) and making us feel awake and positive. If you're indoors, a bright light session is the next best thing and is proven to put you in a better mood, boost alertness and help you to feel more awake, so it's a great way of improving your work environment. It can also be an effective treatment for SAD (Seasonal Affective Disorder) and the winter blues.
Use Brightspark and Desklamp at your desk when you need an afternoon pick-me-up or even have a full light therapy session while you work. Pharos COMPACT is more powerful and offers faster treatment times so it's a good mid-priced option if you're looking to treat SAD.
