It is a known fact flashing lights at a certain frequency can cause seizures. Most of the flashing is due to lousy solder joints on the circuit board inside the bulb.
We had regulations for the arch of a banana and the sharpness of corkscrews.
I think it's more a lack of regulation, allowing manufacturers to sell you crap.
Good, modern LED lamps have a constant-current driver and sometimes a buffer capacitor. These exhibit little to no 50/100 Hz (60/120 Hz in the US) flicker.
I asked ChatGPT. Here's the answer:
1. Cheap drivers behave worse at 120 V than at 230 V.
120 V systems give LED drivers:
- Less voltage headroom
- Higher current for the same power
This makes it:
- Harder and more expensive to smooth the output
- Easier for cost-cutting designs to flicker
At 230 V, it’s easier to design a stable, low-flicker power supply.
2. Regulations and labeling
The EU:
- Has stricter flicker and power-quality standards for consumer lighting
- Requires better disclosure
The US:
- Standards exist, but enforcement and labeling are looser
- Many ultra-cheap bulbs reach the market
This affects average quality, not technical capability.
In my kitchen, I need a light of about 2000 lumen. The brightest E27 LEDs are about 1500 lumen. So, I removed the E27 fitting and put in an aluminium cooling block for commercial LED grow cob chips, that greenhouses use. They are between $1.00 and $1.50, and I buy them at least 4 at the time, all different brands. I had one blow up immoderately, 1 burn out within 6 months, but I have had several now work great for 1 to 4 years. It just requires a little bit more work, because you have to weld on wires. I do that for all 4 of them, when they are delivered. It takes me about 10 minuten to exchange them, because they are screwed onto the cooling block, and sometimes the screw holes don't line up perfectly, and then I have to file out the holes a bit. In any case, that gives us about 2000 lumen for 20 Watt of power. That's about a $65 savings in electricity per year, on an average of 5 hr/day of use.
LED lights are now just as good, but a bit more expensive to purchase. They compensate their higher purchase price with a lower electricity bill. If they are lasting shorting than incandescent light-bulbs, your buying crap products.
They used to be too expensive, but competition forced their prices down.
I also really like the WiZ RGB Smart-bulbs in the bedroom.
Filtering out the blue light at night helps me read without disturbing my sleep, or to have minimal light when I wake up, or to have romantic colored light for "sexy time".
I think I found the product that you are describing. Something like that is using hundreds of LEDs, which increases the risk of failure. I see one for $14 online. That can only be cheaply made in China. You cannot expect it to last. I have a LED construction lamp, with 144 LEDs on it. It gets damn hot very quickly. It's still working, but I don't expect it to last long.
However, all LED-filament bulbs that I have ever bought, at least work for several years. The one in the ceiling light on the landing of the first floor must be about 10 years old.
It's true that you cannot expect to buy the same product again, if you have a set of several and want to exchange one broken one, with the exact same color and intensity.
I always buy them in bulk for that application, so I have spares.

It is refreshing to read more sensible statements about the environmental subject.
"“None of the apocalyptic predictions with due dates as of today have come true.”
The conclusion of the past five decades of failed apocalyptic predictions was that the false prophets shrieking about climate change were doing so to push partisan political agendas.
Just as they have with the overused “Race Card,” Democrats have weaponized “climate change” to stoke public panic in order to push leftist policies that have little to do with the environment and more to do with raising taxes and taking money from one group to give to another.
Brainwashed puppets such as Greta Thunberg should realize they are merely props being used to push destructive, left-wing agendas.""
Grand Canal green. But calling that “polluting historic waterways” is a loaded portrayal;
the demonstrators say they used non-toxic dye, and there is no proof of long-term pollution or damage. In other words: the “ban” and “dyeing” are real, but the “pollution of historic treasures” claim is more rhetorical spin than verified fact.
You are pushing a destructive right-wing agenda; Climate Change is real and destructive
and it's NOT left-wing to want to protect nature, and humanity that is dependent on it.
“None of the apocalyptic predictions with due dates as of today have come true.”
That's an absolute lie, climate change is progressing as scientists predicted.
Many past “predictions” have already come true.
Climate scientists’ projections from the 1970s, 1980s, 1990s, and 2000s included:
✔ Continued global warming
Predicted since the 1970s.
Outcome: Correct. The planet has warmed about 1.2°C relative to pre-industrial levels — almost exactly what early models projected.
✔ More frequent and intense heatwaves
Predicted in the 1980s–1990s.
Outcome: Correct. Heatwaves are now more frequent, longer, and more intense on every continent except Antarctica.
✔ Rapid Arctic sea-ice decline
Predicted in the 1980s.
Outcome: Correct — the summer sea-ice minimum has declined by ~40% since satellite records began in 1979.
✔ Sea-level rise accelerating
Predicted since the First IPCC Report (1990).
Outcome: Correct — global sea level is rising faster today than in the late 20th century.
✔ Heavier rainfall & flooding
Predicted in the 1990s under a warming atmosphere with more water vapor.
Outcome: Correct — extreme rainfall events have increased globally.
✔ Increased wildfire risk
Predicted since the 1990s due to higher temperatures and drier vegetation.
Outcome: Correct, especially in western North America, Australia, Mediterranean, Siberia.
So the claim that “none of the predictions came true” is simply misinformation.
A 2019 study (Hausfather et al., Geophysical Research Letters) evaluated 17 climate models from 1970–2007.
Results:
Most models predicted today’s warming almost exactly once you account for real-world CO₂ emissions.
Their average accuracy was remarkably high.
Classic examples:
James Hansen’s 1988 model: Today’s temperatures fall between his middle (“Scenario B”) and high (“Scenario C”) projections — because emissions grew faster than expected in the 1990s–2000s.
IPCC 1990–2001 models predicted ~0.15°C warming per decade.
Actual warming since the 1990s is about 0.18–0.20°C per decade.
In short:
👉 The warming has tracked very closely to mainstream predictions.
✅ 3. Which scenario are we currently on (best case, worst case, or middle)?
Climate models use different emissions pathways (formerly “SRES,” now “RCPs” or “SSPs”). Here’s where humanity actually is:
🌍 We are not on the best-case trajectory
SSP1-1.9 (≈1.5°C world) → Humanity is not reducing emissions fast enough.
🌍 We are also not on the worst-case trajectory
The old “business-as-usual” high-end scenario
RCP8.5 / SSP5-8.5
is now considered unlikely because energy systems have shifted somewhat away from coal.
👉 We are currently closest to a middle-to-high emissions scenario
Most analyses put us near:
SSP2-4.5 (medium emissions)
or
SSP3-6.0 (high but not catastrophic emissions)
This corresponds to:
~2.4–3.0°C warming by 2100 if current policies continue.
If countries meet their long-term pledges, possibly ~2°C — but pledges are not policy.
So climate change today is playing out extremely close to what mid-range models from decades ago predicted.
'YouTube can be educational too (let's share videos)' topic.
There are three main cycles:
1) ~100,000 years for changes in orbital eccentricity (shape of Earth's orbit)
2) ~41,000 years for changes in axial tilt (obliquity)
3) ~23,000 to 26,000 years for the wobble of the Earth's axis (precession)
They are completely irrelevant for human made climate change, that has the potential
to decimate humanity in a few HUNDRED years, from increasing the temperature,
many thousands of years before the next ice age is due, if humanity DOESN'T ACT.
The reassuring article from Bill Gates, that you posted a while back, takes into account
that humanity DOES ACT, SIGNIFICANTLY MORE THAN WE ARE ACTING NOW.

So why all the hate for cows in the green movement ,but bison are ok? Buffalo's and cows are very similar, similar enough that they are bred to each other.

methane from buffalo

Yes, buffalo belch (or burp—the terms are often used interchangeably for the same action of expelling gas from the stomach).
Buffalo are ruminants, a group of herbivores that includes cattle, sheep, goats, bison (often called American buffalo), and water buffalo. Ruminants have a specialized four-chambered stomach where microbes ferment plant material, producing large amounts of gas (mostly carbon dioxide and methane) as a byproduct. To release this gas and prevent dangerous bloating (a condition called bloat that can be fatal if belching stops), ruminants continually eructate—belching silently about once per minute, unlike the louder human version.
This applies to both major types of buffalo:
American bison (commonly called buffalo in North America): They eructate during specific rumen contractions, similar to cattle. Their belches contribute methane, a potent greenhouse gas.
Water buffalo (Asian buffalo): As ruminants, they follow the same digestive process and belch regularly.
In short, belching is a normal, essential part of how buffalo (and all ruminants) digest food—without it, they'd swell up like a balloon and potentially die.
Yes, buffalo do fart. This includes both American bison (often called buffalo in North America) and other species like water buffalo. They are ruminants, meaning they have multi-chambered stomachs where microbes ferment plant material, producing gases like methane as a byproduct. While most of this gas is released through belching (eructation), some does exit as flatulence from the rear.
Scientific studies on bison herds have measured significant enteric methane emissions (from digestion), with per-animal outputs comparable to or sometimes higher than cattle, and flatulence is explicitly part of how this gas is released. Historic estimates suggest pre-colonial bison populations (tens of millions) produced methane equivalent to modern livestock, including through farts.
The "green movement" hates the BIO-INDUSTRY, not the cows.
It's not the differences between the animals that matters, it's the differences
between how they are living.
Bisons are a wild animal, that lives in harmony with nature. Did you even watch the video? They explained about what Bisons do, to improve nature, all over the video.
The modern cow is an over-engineered animal that ruins nature. It produces 10 times
the amount of milk, and therefore also emits much more waste.
Those Bisons are a few hundred individuals, in an incredibly large area, that has very few nutrients in the soil. Everything they drop and let fly gets absorbed by that area of nature, because it needs it. Cows live at best on a pasture that is saturated by nutrients, and they are living there in populations that are thousands of times denser.
The Netherlands has a problem with cows, because we have way too many of them for such a small country. That creates a massive pollution problem. Austria, for example,
a country famous for their Alp-milk, doesn't have the same problem with pollution from cows, because they have 1/8th the number of cows, in a country twice the size.
At that scale, nature is still able to process it.
Besides, if I was going to raise something for milk I would raise goats. Much better for you
Humanity should just learn to live within the means nature sets for us.
Most cows are not 'gene modified' directly, but are just the result of hundreds of years of selective breeding. It made them great milk and meat factories, but they would die off very quickly back in nature. If humans all disappeared one day, all the cows would die off very quickly. For some races, in 90% of the cases, if there is no vet to winch out the calf at birth, both the mother and the calf will die. They are bred that way.
Most people don't like goat milk and goat meat is even less popular, so I don't think society is going to shift away from cows, any day soon.
I'm not agreeing with many people on the left, that we should go back to a pasture with 1 cow per acre, because there are 8 billion people on Earth. What we need to do is find a balance between poisoning nature to death and starving ourselves, which prioritizes animal friendliness. We shouldn't be cruel to animals, but we should accept that it is impossible to live from nature, like we did 10,000 years ago, with 8 billion people.
I want progression and innovation to make society sustainable for the world. I don't want to go back to pre-historic times and I also fight against the denialism against the reality that we are destroying ourselves, by destroying the nature that supports us.
but a domesticated pig can?"
Cows are bred to give huge amounts of milk. No calf can ever drink that much.
A high-producing dairy cow would die within a few days to a week, if not milked.
Pigs are bred for meat, not milk. We only bred them to have large litters and grow fast. They can eat almost anything, so they are pretty successful in nature. Feral populations will actually establish fast, and can develop into an invasive species.
It's actually nature/evolution that is limiting the reproduction rate of e.g. wild boars, because an invasive species would kill nature, which would then kill itself.
You could say that we created cows to be losers and pigs to be winners.
However, too many winners will collapse the ecosystem.
(which is very much what humanity is doing too)

Reality is starting to set in. electric truck range can't fulfill the needs of folks that actually USE trucks for their purposes.
The Rivians that Amazon uses are van that have a range of about 80 miles, and both drivers that deliver here tell me that they are on pins and needles that last few miles trying to get back to the warehouse.
Do understand that folks that actually USE trucks for their purposes,
are a tiny minority of truck users.
A study by Strategic Vision found that nearly 90 % of truck buyers said they never use their truck for business towing, mobile-office or worksites.

I bet if the cows are allowed to eat grass and natural grains they would be just fine.
Health nuts tell us humans all the time to stop eating processed foods but now we are feeding our meat and milk producers processed food? Does that make any sense?
✅ What is true
1. The feed additive Bovaer (active ingredient 3-nitrooxypropanol, 3-NOP) is being used in Denmark in dairy cattle feed as part of efforts to reduce methane emissions.
2. Denmark has put in place policies to reduce methane emissions from dairy farming — including subsidies/confidence for feed additives — as part of its climate / agricultural emissions strategy.
3. There are reports from Danish farmers of animal health problems (e.g., reduced milk output, cows „sluggish“, some rumen-failure, some culls) after the introduction of Bovaer in some herds.
4. The manufacturer (DSM‑Firmenich) and Danish authorities have acknowledged and are investigating the reports of problems (though they do not conclude causation yet).
⚠️ What is not (yet) clearly proven
1. While farmers report cows “collapsing” and being euthanized, I did not locate independent, peer-reviewed or official veterinary data that confirms widespread collapses/euthanization directly caused by the additive. The media reports and farmer complaints are there, but causality is not established.
2. The claim that the policy “after Jan. 1 2025” mandated the additive in “large dairy farms” and that cows “started giving less milk, collapsing and in some instances getting so ill that they need to be euthanized” is a strong version of the claim and appears to be more sensational than the evidence currently supports. For example:
- The requirement noted in Agriland: “Since January 1, 2025, all conventional dairy farmers in Denmark with more than 50 cows are required to reduce methane emissions by either adjusting feed (increasing fat) or adding Bovaer for 80 days a year.”
- The phrase “collapsing cows” appears in certain farmer-complaint articles and blogs,
but not in official statistical data indicating a systemic collapse across Danish dairy herds.
Also be aware: Some of the articles you quoted (and similar ones) come from outlets with strongly charged language (“cows drop like flies,” etc). These may amplify or interpret anecdotal reports without full vetting.

Feeding cows "processed food" has been going on for a long time, with the goal
of maximizing profits. Your mental image of cows grazing in the pasture is obsolete.
31% of cows in The Netherlands never comes outside, the rest only (a small) part
of the year.
When they are inside, they are eating processed feed. Most farmers have their own production pasture or grain field to grow ingredients for the feed, but almost all of them
add large scale produced feed and additives.

The animal feed industry in The Netherlands has an estimated annual revenue of approximately $16.5 Billion.
Cows are milk and meat factories and don't get treated as animals that can suffer.
It's your side of politics that created that, and it's NOT your side of politics that is
aiming to make farming less cruel to animals. You celebrate 'profit over people',
so why would you care that profit hurts animals?
Feed additives like Bovaer are an alternative for reducing cattle.
Denying the reality of climate change is not helping anyone.
At least in Denmark they are trying a compromise. You better hope it works,
or you can say goodbye to milk and beef altogether.

So much for all this criticism of America for not being tolerant of those that speak their minds. Europe is nothing but a large gathering of hostages of intense brain washing and hypocrites.
Throw yourself on your fainting couch for getting some hate back.

The side that you think is brainwashed, has science, facts and logic on its side.
Your side has nothing besides conspiracy theories and projection.
because they are investing in “climate solutions”.
Using my facts to disprove the theories? Your theories? You don't have any.
There are thousands of scientists trying to prove climate science wrong.
That's how science works. Instead of proving it wrong, they end up confirming it,
with every attempt. None of your articles that are trying to debunk the science
of climate change are actually doing science. They are just doing propaganda.

A retirees' fund can be held liable for wrong investments, particularly if the fund's fiduciaries have acted imprudently or breached their duties. Under laws like the Employee Retirement Income Security Act (ERISA) in the United States, fund managers and fiduciaries must act solely in the interest of participants and beneficiaries, and carry out their duties with the care, skill, and diligence of
a "prudent person". Do you have evidence that these were wrong investments,
other than the fact that they lost money?
Maybe the CETF manager is a crook. If CalPERS had no reason to suspect that,
they are not liable for the loss.
I just told you that it's a loss of 0.06% of its total value.
Do you instead investments, at all? The principle is to spread the risk over many investments, because some will lose money. Their overal return is ~14.3%.
That's very good for a retirees fund.
