I have had my KenkoLight full-spectrum lamp for just over a year and a half and I love it. There is one thing that I have to strongly caution you about.
It will show you how bad the rest of the light is in your home.
I used to think I could see OK under incandescent and fluorescent lights until I started using my KenkoLight. Now I see how yellow and inadequate other light sources are, to the point where I have difficulty seeing by them.
It might actually make you think that you eyes are starting to give out on you until you realize that you can see quite well by your KenkoLight and by natural sunlight.
What’s actually happening is this. Right now you do most of your reading by incandescent or fluorescent light, regular light bulbs. Your eyes are straining to see clearly and you don’t notice the strain because it is a part of your normal experience. The strain may show up as headaches when you read a lot or maybe you feel tired after reading.
When you start using your KenkoLight to do your reading your eyes won’t have to strain to see because what you are reading is properly illumined. Over time, the tension in the muscles that focus your eyes will relax and go away. You probably won’t even notice that it is happening.
Then all of a sudden, one day you will try to read something by an incandescent light bulb and you will have trouble seeing it clearly. Your eyes are no longer used to having to strain to see. Move to your KenkoLight or a sunlit window and you will be able to see clearly again.
This isn’t just about full-spectrum light. After I bought my first KenkoLight I decided to try a so-call full-spectrum replacement bulb in a light fixture in my livingroom. I don’t remember which fixture has the full-spectrum bulb and which has the regular bulb because there is no discernible difference between the two.
The full-spectrum bulbs that you can buy from a store may have all of the frequencies of sunlight, but they don’t have the same balance of frequencies that exist in sunlight. That is the difference, and the difference is very noticeable.
