I am loving my light so far. I get up very early, way before the sun. I find that if I use my light for about 30 minutes first thing in the morning, it helps me feel more focused and energized going into my day. I really feel this bit of "sun"light is helping me refocus and feel that energy that these cool dark mornings were laying on me. I definitely will be a customer for a long time to come of your great products.
