@3500GMC Both the above sites and this one give more depth to the problem that also affect LED screens like TV's, Cell Phones, and computer screens. Blue light is one suspected cause as well as the ON-OFF of diodes vs. the smooth dim and brightness that incandescent lamps have. Fluorescent lamps also have a smoother bright dim as the phosphor glows some after the arc goes out when the AC polarity changes. The Magnetic ballasted fluorescent lamps make me sick. I have to start wearing a hat indoors due to all the new LED lights showing up in retail stores. Even the ones that don't strobe or flicker are "Harsh" and IMO the blue light overpowering the rest of the colors is part of it. Look at any of the graphs even from the Waveform site and there is a blue peak. Some LED's are painfully bright to me while the lumen rating isn't so high.

I did try one of their blue free LED lamps. (I run some Red LED's and high frequency fluorescent in the evening to save night vision.) Although it doesn't bother me the blue free really bothers other family members of mine who also suffer from the same problems I have.
JTL does sum the situation up well link/post below. Lack of research = therefore there isn't a "problem". Further "It doesn't affect me so Too Bad. Next item to do?"

Over the years I have solved many headaches (literally) for users by changing the 60Hz refresh rate on now obsolete CRT computer monitors to 72Hz or higher. Even identifying WTH do I have a damn headache every single day may be ignored by most people.
When it becomes a migraine where the center of your vision is a black hole ones goes to the ER. When you see an aurora like "Heat Waves" coming off the road in your office you go to the ER. Pass out and wake up vomiting resulted in a year of medical fun and then playing the ADA card with my employer where simply relamping the office with high quality high frequency ballasts and new T8 tubes helped. Sadly the tubes age and will strobe and flicker at end of life.
The LED flick on a moment then off flashing due to failure modes is an extreme problem for me. Of course no one can be FN bothered to take the light out of service or repair it in a timely manner.
Although one may think this is OT I actually serve as a warning. If the one starts getting headaches etc. from the new lighting... Well good luck avoiding the problem as everywhere is changing over to is just as CHEAP and fast as they can.
The H.O. tubes in some fixtures I had were not lasting very well before the lamps went bad. So it was a real gamble to switch to LED vs. renewing with high quality high frequency ballasts. Even with 30 day free shipping on returns from the LED vendor the fixture wiring changes are time consuming.
