KM For the last few years I have been using a combination of different light sources: CFLs(philips，osram) in places where I don't spend much time like in the hallway/bathroom，I use LED lamps(warm 3000K) that have a DC transformer with the light flooding the walls(I don't like direct LED light) at the same time with desk lamps and floor lamps with halogen light bulbs in rooms where I spend more time.
I also have a Panasonic plasma tv，I use my laptop at maximum brightness with a software color filter to dim the brightness and use f.lux with 4500K for the day setting. At work I bought a Dell u2414h(DC driven backlight) at 44% brightness in the “Paper”(low blue light mode) monitor profile and f.lux installed with 4500K for the day setting and have no red eye/head aches/sand in the eye sensation after 8 hours. The light at work is from fluorescents with electronic balasts(nothing show when I filmed in slow motion).
I own an LG Flex2(flicker-free) on which I do a lot of reading daily.
I've been a computer programmer for 7 years now and got to the ophthalmologist recently and I still have 20/20 vision. As you can imagine I had a lot of problems at the beginning(there was very little on the net at that time，felt like I was the only person with PWM health problems) so I did a lot of research and that is my current setup.
I currently found 2700k or lower LED spotlights and light fixtures(with DC transformers)，OSRAM DULUX INTELLIGENT LONGLIFE CFLs which are suppose to be flicker-free and a very warm CCFL light bulb(these are rare). I will try to combine all the the best from all the lighting technologies and I will let you know how it goes.
If you want specifics on which LED lamps I use etc. ask and I will give details in another post as this post is already too big.
