Flicker Free LED Lightning it's the most important thing! Which one to buy?

jen It reads more or less like my symptoms. It is not only light nausea, new monitor are sometimes even doing a thing, where my body is like getting food poisoning, i get diarrhea. Testing my new OLED TV, i am shaking like crazy. I can send the TV back, it is not about that. I have fear of going into the office again, i cannot hide this in office. My worst device is my work laptop. And you cannot have another sort of laptop at my work!

At one point my Eizo had like colored subpixels around the black text. I think that was my brain. It is gone, no it is just massive eye sore.

Perhaps i get an e-ink reader monitor when i go to a doctor.

hayder1983 Perhaps i get an e-ink reader monitor

If possible try it in a way you can still return it. An eInk computer monitor (Dasung) is at least as bad if not worse for me than the normal monitor - the eInk amplified the visibility of temporal dithering. It was obviously flickering grayscale pixels on eInk instead of the “invisible” flicker from dithering on the LED LCD monitor.

I can even switch off dithering on the OLED TV, my eyes dont cramp, but I am shivering. My brain does not like it. The picture is fantastic especially with low brightness. I will give it one more day, if it is unusable tomorrow, i will send it back. I dont think it is dithering with the TV, even when there is still some hardcoded dithering. I even tried it in store with cheap lighting everywhere. At home with no lights and mild daylight, it doesnt work… but i can return it

But wow. What the hell. If i dont find new technology that i can use, i will get old tech to use. I have still 28 years of work in front of me… Some old superlow contrast monitors, unrefurbished. Watching TV on my old monitor is easily possible. I can see the dithering on my screen, but as long as i use black background and grayish text for my browser and dont look at static images i dont see it. White is dancing for me(not on every device, but on my PC). It seems there is no way to turn it off on my new PC

The thing is it takes away life quality to not be able to watch TV with your family or cartoons with your children. I will use my old TV, it "only" gives me eye strain, that is ok for 2 hour movie, as long as my eyes can get through 8 hours of work.

I am just now using a philips filament bulb. My eyes arent twitching, i cant see a flicker, no nausea. I just tested it a few hours, but my eyes are totally sore from work and still not acting up. It means no flicker or acceptable flicker. It is not dimmable, but not super bright when postioned behind you, so it is usable as ambient light for my PC, perhaps in the living room. It is still not the same color temperature as a normal light bulb, but acceptable.

I will test it another few days and as soon as i get the other 3 light bulbs i will share again.

waveform did not work for me, but they have free returns, so worth a shot.

hayder1983 You can see if a bulb flickers or not by clicking on the "Product fiche" link on Amazon (for countries in the EU) near the energy label. Search for the values of Pst LM and SVM at the end of the document, for this Philips bulb the values are Pst LM = 1,0 and SVM = 0,9, which means that the flicker is strong.

For a flicker-free bulb the values should be near Pst LM = 0,01 and SVM = 0,01 (for example this bulb : https://www.amazon.de/-/en/GreenAndCo-Filament-Light-Dimmable-Flicker-Free/dp/B01E7FM3GW?ref_=ast_sto_dp&th=1&psc=1)

You can find flicker-free bulbs on https://www.derlichtpeter.de/en/light-flicker/market-tests/, you have to search for CFD: <1%, FfT

insta42014 Well this is very strange. My eyes are not revolting with the philips LED. Perhaps there is a reason my eyes accept a lot of the cheaper LEDs i bought years ago and only a few of the newer ones. My eyes are totally ok with halogen lamps, we have them in the bathroom and actually like them. 100hz seems fine for my eyes, HUE(1000 hz) not so much. Perhaps these Phillips bulbs are more like 100 hz? 312hz laptop screen is super hard to watch for me, 1000 hz is better. But everything could have more than one reason, perhaps i mix up things.

I also ordered this one(data sheet below), which seems to be 100.000 hz. There is no value for Pst LM and SVM, but i will try.

But i would prefer flickerfree, i just ordered 5, thank you for your suggestions

I found that list not to be as helpful as it first seemed. The bulbs I bought after studying the list flickered, perhaps because manufacturers regularly replace their bulbs which different wiring. Ironically, the worst LED bulb I have, by far, is an "FfT" GreenAndCo from that list. It makes me feel sick, disoriented real quick. It has no fixed frequency - instead, the frequency seems to change rapidly, producing a noise. For me this is not a bulb but a weapon. How they can sell something like that and put a "flicker-free" sticker on the box is a mystery.

I could just use my eizo as a superexpensive LED Panel and place it facing the wall

Most important thing is that my eyes dont twitch and dont dry out from the light. Worst case i keep using the flickery philips bulbs or halogen, because my eyes somehow like them. Perhaps 100hz halogen flicker is easy for my brain to filter, because it is slow enough?

Seems like hue white and color is using 100hz PWM with a flicker index of 0,3(if they didnt change sth). I find that good to know, because i find them barely acceptable, so flicker index of 0 should be less strain?! And it seems like my eyes like 100hz flicker more than 1000+hz flicker.

I will share when i get the paulmann LEDs.

seeker_of_no_light Paulmann light bulbs arrived. I used them for a day, just for ambient light behing my monitor. Very nice. Nice color temperature, light does look a bit like an old light bulb(not exactly, but close). And they really have very little flicker(at least to my eyes). Better than any bulb i tested so far. I will test the e27(3,5W and 5,5W) for the kids room.

hayder1983 thanks for the update. Interesting indeed. I'm really satisfied with my Waveform light bulbs, but I definitely will try to give these a try, not only are they basically gifted to you, but I would love to have something along the lines of 200 to 400 lumen, because having an option to light my transparent DIY monitor experiments during nighttime would be nice and unfortunately all of the Waveform lightbulbs are way too bright to my eyes for that type of usage

seeker_of_no_light I ordered a flickermeter. I think it only can go up to 100/120hz, but it is enough for light bulbs and measuring lux, flicker index, flicker rate(it calculates everything according to description). I ordered it to sort out flickery/defective LED light bulbs. I will try it on my new lightbulbs and share afterwards.

I have a small Lithium Iron Phosphate battery and a 12v DC Floodlight that I use connected directly with clamps to the battery. It SEEMS pleasant but I can't test it with a flicker meter or anything.

From what I understand, the USA ban includes rough service bulbs too

ryans From what I understand, the USA ban includes rough service bulbs too

That's awful. I wonder if it'll include christmas lights.. I'll have to check that.. but that aside, you can order rough service from Amazon Canada. And barring that, other countries through Alibaba, etc.
