When my 18" flourescent, under-cabinet light went kaput; I went to Walmart and looked for a new one. All they had were LED daylight tubes. I bought one and installed it. When I turned it on, that sucker was illegally bright. It was like having the sun in my kitchen. Thankfully, the fixture had a clear plastic shield on it. I took some white duct tape strips and stuck them on the shield leaving only 1/4 to 1/2 inch slits for the light to shine through. Good God. No wonder eyesight is being damaged. If they are going to sell retina killers like that, they need to offer free light filtering covers for them too. No one needs blinding white light to see at night, I'm talking those headlights, not cool.
