@suosuo If you're monitor is adjusting it's brightness when you enable f.lux and your screen has "pulse width modulation" or PWM backlighting, then it may be the cause.
If you could open your monitor menu and go to the info section and let us know your model we can all search it for PWM. That would be the first step I think. Another thing is, how old is your monitor, if it's got cold cathode fluorescent lamps, and they're five or six years old, then it's time for a new monitor.
No, the heat generated by the LED light's power supply must be dissipated or else it will overheat and die. This is why LED lights should never be installed upside-down, inside enclosed fixtures, in hot areas, etc. Yes, they don't feel hot immediately like an incandescent does, but that's because it takes a good 15-20 minutes to become hot. They also don't radiate this heat outward like an incandescent because nothing is burning. In an incandescent, the filament is burning, thus it's instant radiant heat.
Even the heat created by all of the LEDs themselves must be dissipated.
Until we humans can figure out how to generate power without heat being created as a result, we will always need to dissipate that heat or else it will build up and build up and overheat.
@lordofweed The goal is to have less blue, not make more red which can appear similar but, means you're still seeing the same amount of alerting light, make sense? https://fluxometer.com/rainbow/ check this out and see how f.lux and different filters change the spectrum.
@herf cool, so just a hair past blue is more violet blue instead of regular blue! I had always wondered this as led bulbs have that half blue / violet spike and maybe that's part of what makes their strange tint, example GE's Align PM. I think the lack of aqua / cyan also plays a big role in the off blue/violet tint.
Yeah, it's going to be decades, if not centuries, before we humans evolve to that point. We humans are just now barely beginning to wake up to lots of things, such as what we are discussing here. When you really think about it, you realize that we are actually still very primitive. However, we've sort of made this illusion that we're quite advanced. Think about it though! We're still quite primitive.
Anyway, I don't think it's that people aren't really paying attention, but it's that it truly doesn't bother some people as bad as others. Refer back to that Psychology Today article on the "Pupillary flutter". They talk about individuals with Autism, and, well, I have Asperger's Syndrome which today is just being called "Mild Autism". So, I'm not surprised that I have a problem with fluorescent lights and even LEDs. I'm not surprised that I strongly prefer natural light and incandescent light.
The only reason why I prefer LED lights over fluorescent though is, they're cheaper and they don't create "dirty electricity", and also that true incandescents are pretty much not worth trying to find anymore. Well, Aero-Tech has the best incandescents, but they don't make a good old-fashioned 3-way. Their only 3-way from what I can tell is a full spectrum bulb.
I am very interested by the concept of filtering out the blue light, but I am noticing that since using these blue light filters on my PC and phone, I have a banging headache. I actually feel strained looking at the screen with the filter on (when I turn it off temporarily, admittedly it's even worse, it feels like I am being blinded!)
Has anyone experienced similar issues such as eye strain and headaches when using the filter? Also, has anyone noticed that they feel they sleep better and feel refreshed etc since using f.lux?
The eye strain and headaches you are experiencing may be caused by setting the screen brightness too low for your eyes to focus comfortably since warmer colors have lower intensity. Try adjusting the brightness a little higher than the current setting that is causing the strain. You can also adjust the lighting in the room that you are using the device in to a brightness that is relatively lower than your screen. Also avoid having just certain areas lighted in your room, like a lamp that only lights up a small area. Non uniform lighting around you can also affect the eyes.
Hope these helps rid you of your ailments. Cheers.
