21st century technology has improved upon the Edison lightbulb and developed fluorescent phosphors that reflects balanced color with trace amounts of UV. 
They meld into a bright, white, clear light that replicates sunlight, indoors.  In addition to illuminating a room, people and contents, it offers many of the benefits of natural sunlight which enhance health and well-being. It also has a proven energy efficient technology resulting in energy savings up to 70%. 

The secret lies in how sunlight stimulates responses in the body that can help to reestablish the body clock which controls timing of sleep, hormone production, body temperature and other biological functions.  Virtually every living thing developed under sunlight, made up from a balance of color and invisible ultraviolet wavelengths. 

The lack of natural sunlight due to our indoor lifestyle can cause biological problems.  Examples include:  lack of Vitamin D (sometimes called the sunshine vitamin) which works to regulate replication of cells, key to calcium and developing strong bones, SAD-seasonal affective disorder/depression-which uses sunlight therapy as a proven treatment, and vision acuity because full spectrum lighting activates 80% more cells in the eyes making everyday tasks easier and improves safety.  Also promotes productivity and increases sales.  See more information under Benefits.
