Flicker free LED lights

ctsai89 I have not. My allergy theory comes from my ENT (well, one of the 5 ENT's I have seen over time). They studied the Sinus/Allergy/Migraine connection a lot, and their theory basically went like this: Everyone has a "threshold" where a stimulus (light in our case) can cause a reaction in the brain leading to undesired brain activity (migraine, ocular muscle spasms, strain, etc). For most folks, this threshold is high enough that stimuli like lighting never crosses that threshold, so they never have any issues. For us, our natural threshold is much lower, so that same stimulus DOES trigger a response.

His theory/statement was that allergies and other inflammatory issues lower thresholds even further, so even more stimuli cross is and trigger an attack. The two big "threshold movers" he talked about were weather (the link between migraines and weather is well known) and allergens.

I have uploaded some of my letters to my subreddit, /r/lightsensitive for use for anyone who wants them. I am no ones poet and have not updated the BULB letter in a while, feel free to edit/modify and use.

I think there's pretty much only truth to that. I had dry eye/eye strain from my first LED monitor which was a macbook back in 2010 only for 3 weeks but I was young back then. My dry eyes/eye strain officially became a chronic problem 7 months ago when the weather got cold and all of sudden we were getting rains everyday here in southern California. THere are different pollens for every season weather. On top of that, some family member of mine brought home huge amount of flower and kept it in the house for 5 days making the house smell unbearable. My eyestrain threshold has been so low ever since, to the point where I am turning my screen down to 0% brightness + plus another brightness slider to lower brightiness + influx basically turning down blue light as low as possible. THe newest thing I am trying now is lowering the contrast to 30% lower than the default, this seems to help a bit more as well.

So pretty much with the theory (if proven) in mind, the environmental supremacists/LED fanatics could legitimately claim that LED doesn't cause any problems and that we should have our auto-immune disorders fixed first.... am I correct?

anyways I am going to take a look at your subreddit post now. Thanks a bunch!

I would not say thats the case. When people have a problem, you accommodate them. Light sensitivity is a disability like any other. If you were in a wheelchair, people shouldn't not build you a wheelchair ramp to save wood. It's not worth the effort.

Also, it's not sure our thresholds CAN be raised. Given the absolutely minimal environmental benefits, and the well document legitimate health hazards LED lights present, there is simply no reason to use them. The price in human suffering is not worth it. They are simply unaware of the effects that we suffer from, so they are forming their opinion from a place of ignorance. It is our job to educate them so they realize the benefits of LED's are not worth the suffering and damage they cause

I hope so

I feel like the problem is that most people who have the same problem we do don't have as severe to the point where they have to turn the brightness level to below 0. I've talked to a few and some say "sure LED is too bright that's why I wear protective glasses and I'm fine now" they would stop right there and wouldn't give a damn or two about it beyond that.

How rare/common is it to have the threshold so low to the point of suffering like we are? I came across a site and it claimed 1/4000 people but I don't have the link of it anymore.

From my research, roughly 10% of people suffer from this level of photophobia.

JTL If anyone could bring back incandescent lightbulbs, it is Donald J Trump

Yesterday I learned that while you can still, from a few sources, buy regular old incandescent bulbs in EU countries, their import is banned since February 2016. So they really sell the rest now and it's declining each day. And you can't import them anymore. Not even from China. I advise anyone who lives in an EU country to stockpile now before it's too late.

Please do write your congressmen, and the president stating your desire to see the EISA restrictions removed. Ask them to reconsider The BULB Act (H.R. 2417) which removes these restrictions. This is a rare chance to get this done given the current administration we have.

KM After further investigation I found out that FfT bulbs are indeed flicker free. BUT these bulbs are very sensitive to the input electricity. If the input is not perfect these will flicker and will give you a headache like you mentioned.

You should test that "Flicker free technically" bulb you bought with a UPS(disconnected from the mains to generate perfect input for the bulb, otherwise you will get the same input as the mains) or with a Voltage Regulator.

Let me know this works.

Apparently the UPS has 0 ms transfer time
