We are in rainy-cloudy Oregon. A blanket of clouds hides the sun, shifting and muting the colors of light that reach us.It tells our bodies that we should eat more carbs, sleep more, and slow down. Society, however, requires us to maintain the same hours as summer and enjoy the same activities. Our bodies and minds say no-o-o. We call this S.A.D.; Seasonal Depression Disorder.

The light of the sun clues our body to morning and evening activities. The clouds of winter hide the subtle color shifts from the sun that tells us the time of day. We use this light to compare the Kelvins of light bulbs.

Light created by humans lights our homes and businesses

but it does not have the same color shifts to replace

sunlight. By selecting bulbs with comparable light colors, called Kelvins, to the sun for our activities, we can help our bodies experience a bit of the sun's colors. The key to using light bulbs to replace sunlight has two very

important elements. The color, or Kelvin, to match the

time of day or night you want to replace and how close the light is to real sunlight or the CRI-Color Rendering Index.

With few exceptions, fluorescent bulbs are 82% of natural light. Halogen and Zenon lights are 98 to 100% of

morning sunlight. LED bulbs range from 70% to 90% of sunshine. To select 90%, choose a bulb with the Kelvin number -927, 930, 941, 950, or 965 in the code that will be printed on the box.
