No it is the opposite, after reading this topic all the confusion is cleared and you finally know exactly what bulbs to useThanks now i dont know what light bulbs to use
I have measured a lot of screens, too!
The flicker and blue light really seems to be correlated to price of the device.
The best by far was Bravia LED TV. I wasn't able to detect any flicker at all. It was better than all the light bulbs I have tested. You can also adjust color temperature / balance on this TV, and when you set it to "Warm", it produce very little blue light.
I have two HP laptops. One very expensive mobile workstation, one ultra low-end budget laptop. The expensive one has no flicker when powered by battery, and very little flicker when powered by AC adapter. The cheap one was by far the worst thing I have measured, both flicker-wise and by the amount of blue light.
I will not use the cheap one again.
Hey! Why is it harmful? You mean just because of the wavelength or something else?Red leds are okay but I don’t enjoy led lighting and there is evidence that it is harmful.
Interesting idea. Anyone know!Hey! Why is it harmful? You mean just because of the wavelength or something else?
And what about using those LED bulbs for indoor growing (philips has them) on flowering period? They are mimmicking the sun, otherwise plants won't flower. That should be quite good no?

My experience with bulbs for indoor growing is that manufacturers generally doesn't care about their flicker at all. Plants don't mind.Hey! Why is it harmful? You mean just because of the wavelength or something else?

So you are saying you prefer a worse spectrum but lower flickering?My experience with bulbs for indoor growing is that manufacturers generally doesn't care about their flicker at all. Plants don't mind.
But haven't tested high end brands like Philips. Might be okay, but I would be very cautious.
They don't have better spectrum, though.So you are saying you prefer a worse spectrum but lower flickering?
Philips nornally has all technical details in PDF for all their professional bulbs.
Wow! Thanks a lot mate! You really became knowledgeable on this.They don't have better spectrum, though.

You want the spectrum to be as close to evening sunlight as possible. Narrow band lights are super unnatural and not suitable for general use, IMO.
Hey @BearWithMe would you mind sharing the exact IKEA code for those 2700k LEDs with low flickering?Wow! Thanks a lot mate! You really became knowledgeable on this.
Yes I am going to buy some of these 2700k LEDs for the evenings.
Now I'd like to find some for day because we have here many months with very little sun. Any suggestions?
Move to better place. No artificial light can replace natural sunlight. Your mood and overall health will improve tremendously.Wow! Thanks a lot mate! You really became knowledgeable on this.

I know man. I know... But right now I have to be here.Move to better place. No artificial light can replace natural sunlight. Your mood and overall health will improve tremendously.
And yes, you can move, unless you live in totalitarian country like North Korea (and even if you do, you can probably find a way to escape).
Something simpler? Would the same LEDs but 6000k work for daytime?If I would absolutely have to use artificial light instead of natural sunlight, I'd probably use DC powered halogen bulb with UV filter removed.
I knew you are going to say that.I know man. I know... But right now I have to be here.
These are my favorite IKEA bulbs. They are also the cheapest. Currently for 0.3€. Ikea code 204.387.07. No flicker, good spectrum.Hey @BearWithMe would you mind sharing the exact IKEA code for those 2700k LEDs with low flickering?
But dirty electricity is only a concern if you are close to the wires/bulb/socket no? And you should be always away from those anyway.I think the opposite. Listen to the dirty electricity from any LED-based tech. Analogue tech like passing electricity through something like tungsten and emitting heat is a lot more fool proof. Just think about how they're "saving electricity" - I want more electricity converted into & absorbed in the form of energy
Thanks man! Those are 4.5W right?These are my favorite IKEA bulbs. They are also the cheapest. Currently for 0.3€. Ikea code 204.387.07. No flicker, good spectrum.

It is not life. It is 1 more year max (unless covid situation gets out of control). It just takes some patience.I knew you are going to say that.
No, you don't.
What you really can't do is spend your life in poor health.
