Has anyone noticed that warmer light LEDs causing blurrier text. I did a test and found that my cool light LEDs made small text stable and readable while the same text under warm light was blurry.
There's something off about LED bulbs

#12LED bulbs make me made because I can't yell at my kids to turn off the lights like my dad used to do to me.
Sure you can. My wife yells at me all the time. I says they are LED stop complaining. She says they are still wasting energy, doesn’t matter the amount.

#13I have found that there can be huge quality differences between cheap and more expensive LED bulbs as well. Specifically the ones that use a cheap rectifier. Sometimes I think that I can see them flickering out of the corner of my eye.
Re: There's something off about LED bulbs
#14I have heard that newer LED Bulbs now have some kind of built in obsolescence. This is from someone I know who is an engineer working for the US military. I told him I had bought some LEDs (started moving over 2 years ago) and that is when he mentioned that. I guess I will find out, so far so good. I did stock up on 100 watt incandescent years ago and have a many left just in case. I found LEDs cause me eye strain, b…
I'm finding this true with the bulbs I've bought in the past 5 or so years. The first one I bought about 15 years ago is still going, but most, if not all more recent LEDs have died. Even the ones in the basement that are mounted with no case to increase the heat around them. I read the "guarantee" when I buy new bulbs but who keeps receipts or track of light bulbs?
You can write the install date (and store name) on the bulb housing with a sharpie when you put it in the socket. It's not a receipt but it at least gives you a shot at getting a return when it fails early.

#15I am sensitive to low refresh rates - back in the crt days I would visibly notice low refresh monitors and it would give me headaches. Some (low cost?) led bulbs give me the same effect- I can see the rapid flicker. Some hotel rooms are notorious for this.
I have led bulbs everywhere (new build, recessed lights). Thankfully they don’t have the flicker effect I’ve seen on other bulbs. And I’ve found that I actually prefer the more “daylight” bulbs in certain areas such as kitchens. The cans do have adjustable color temperature (a physical switch) so it’s not too bad if I decide I’d like a warmer light down the road.

#16Some of my LEDs continue to glow faintly when off. I assume the efficiency of the bulbs is converting a small trickle of power into light. Has anyone experienced this? Anything to be done?

You can - I see the same thing

#18A smoke-test i had not really thought of: shoot a quick video in slow motion on your phone and watch the result to see if there’s a light flicker .

I have had the flicker effect with some of the particularly cheap LED work lamps

It's probably just lowers the effective perceptual contrast between a page and the printed text. It's pretty understood that cooler light is better for visibility.
