What is your opinion of full spectrum natural sunlight bulbs? I understand they are suppose to be effective for S.A.D. Without a doubt they are brighter than regular bulbs. I know they use less energy. However I have heard they produce a harmful Ion.

%26quot;Full spectrum%26quot; bulbs mimic sunlight. They%26#039;re mostly good for plants. The don%26#039;t produce ions, but they do produce ultraviolet light (UV), which can be harmful, particularly to your eyes.

SAD patients use unusually high intensity light, and that intensity with UV is a very bad combination. Bulbs for SAD are NOT full spectrum, they are specifically designed to emit very low levels of UV.

Do not expose yourself to large amounts of %26quot;full spectrum%26quot; light.

Do NOT try to treat yourself for SAD. The light intensity involved can be dangerous. Work with a doctor who can help you do it correctly. Your eyesight is at stake.

  I also found it more pleasant to read by. Just a slight difference in how the pages look.
