World Becomes Brighter as Trump Reverses Biden’s Incandescent Light Bulb Ban

And user-friendly toilets, dishwashers, and showers are coming back soon, too!

From Legal Insurrection

Posted by Leslie Eastman 

President Donald Trump has spent another day reversing Biden’s efforts to limit consumer choices over products that limit their options and hinder their quality of life.

In the name of efficiency, Biden’s bureaucrats banned incandescent light bulbs, normal-flowing toilets, and effective shower heads. Trump has just instructed his Environmental Protection Agency administrator to bring them all back.

Here is the USAID subsidiary Politico’s hot take on the subject.

“I am hereby instructing Secretary Lee Zeldin to immediately go back to my Environmental Orders, which were terminated by Crooked Joe Biden, on Water Standards and Flow pertaining to SINKS, SHOWERS, TOILETS, WASHING MACHINES, DISHWASHERS, etc., and to likewise go back to the common sense standards on LIGHTBULBS, that were put in place by the Trump Administration, but terminated by Crooked Joe,” Trump posted online Tuesday.

Zeldin is the administrator of the Environmental Protection Agency. The Energy Department — not EPA — is responsible for establishing efficiency standards for consumer products and appliances.

Still, the post echoes Trump’s long-time criticism of efficiency standards put in place for products, like shower heads and light bulbs.

LED bulbs have been a standard replacement for the incandescent bulbs. There is myriad of reasons to deride the blue light that LED bulbs emit.

Blue light suppresses melatonin production, disrupting circadian rhythms and making it harder to fall asleep. This is particularly problematic when exposed to blue light in the evening or at night.

From the American Academy of Ophthalmology:

Blue light does affect the body’s circadian rhythm, our natural wake and sleep cycle. During the day, blue light wakes us up and stimulates us. But too much blue light exposure late at night from your phone, tablet or computer can make it harder to get to sleep.”

Prolonged exposure to blue light can cause eye strain, resulting in tired, sore, and dry eyes. This can lead to blurred vision and headaches.

So, once again, Trump is right. And many Americans are thrilled with the news.

Holy cow! Am I really getting my incandescent light bulbs back? Yeehaw. 😊 https://t.co/gxdjYQz1U9

Low-flow toilets often struggle to flush away all waste due to the reduced water used per flush. This can lead to incomplete waste removal, requiring multiple flushes, defeating water conservation’s purpose.

Insufficient water flow can cause waste to accumulate in sewer lines, leading to backups and unpleasant odors. Cities like San Francisco experienced significant sewer system issues due to the widespread adoption of low-flow toilets.

The city of San Francisco is dealing with its lack of flow with $100 million in system upgrades, and a controversial $14 million plan to pour bleach into the sewer system to neutralize the odor and disinfect the water.

Trump, again, is proven correct.

Who’s happy that Trump just gave us back the freedom to actually use our sinks, showers, and toilets like normal people? 🚿🚽💡

No more trickle showers, no more weak toilet flushes, and finally—your washing machine doesn’t take two hours per load. 🤦🏼‍♀️pic.twitter.com/db1pt4DPDq

Finally, “high efficiency” dishwashers are ironically named. These dishwashers use less water, which can result in dishes not being cleaned properly. High-quality dishwashers may run up to 2-3 hours per cycle to compensate for lower water usage. Lower operating temperatures in eco-friendly cycles can lead to dishes not drying completely, requiring the use of rinse aid to promote water runoff.

I’m a fucking retard if I’d waited another month I could have gotten a dishwasher that doesn’t take THREE HOURS to run

I think I’m going to return it. And get my TRUMP DISHWASHER https://t.co/bZVWY7Q6Hn pic.twitter.com/EcLWOII2zp

So, again, score another one for Trump.

Personally, I am planning to load up on the incandescent bulbs as soon as they become available.

Hunh? I thought their sewage problem was more above ground! Maybe they can provide buckets for citizens to use, and save the toilets for liquids only! That’ll increase the number of Green jobs, too!

LED bulbs were actually a major reason for the relatively flat trend of US retail electricity consumption since 2010.

I don’t mind LED bulbs but my wife hates them. So I bought many dozens of regular bulbs before they were banned. I bought enough 4 watt nightlight bulbs, at 4 for $1.50. for the rest of my life.

All of the “efficiency improvements” from 1.5 gallon toilets, low flow showerheads to more efficient gas furnaces cost more money or don’t work as well as what they replaced. That includes LED bulbs that NEVER seem to last as long as promised.

I actually like warm white LED bulbs. If I can’t have incandescent (and I no longer can) they’re OK. In fact, if they lasted significantly longer I’d prefer them. I have several light fittings that require a ladder. If I could get anything near 10,000 hours out the LEDs I’d be a complete fan-boy.

(I doubt it is the LED part that fails. I suspect it’s the electronics. And I suspect they fail because of low-lead EU-mandated solder. So off to the landfill with them, all too soon.)

I only buy high CRI (minimum 90CRI) LEDs for light fittings. But it’s hard to find them at sensible colour temperatures. 2700K looks very yellow. Really need 3000K for most settings. My Serious Reader reading lamps are 98CRI, 4000K, and are excellent for giving good colour rendition and good illumination when needed: not cheap though. They both tame the blue and properly cover the red.

I just bought and installed a smart LED bulb, I can pick any color from yellow to white. The app on a phone lets you pick the color tapping a in a circle that runs from bright white to yellow. I move it back to bright white since that look better in the place the lamp sits, you also can dim and turn it off and on using the app. In my case I use voice commands to control the lights in the living room where the lamp is. I live in Arizona and the early LED lamps did not make it through our summers outdoors. The ones in the last few years do not have that problem. If you go to you tube you will find out why so many fail early, they string the LEDs in series, bypass the bad led the lamp will work again. Personally the time to “fix” an led lamp is not worth my time, ditto for Christmas light strings.

I used to heat our well house with just a 100 watt light bulb, in such an enclosed space, it kept it from freezing — light bulb plugged into a freeze-protection outlet — turns on at 35 F.

LED lights fail early due hight temperatures or higher voltage voltage which also overheats them. I had a lot of early failures with Chinese lamps years ago. I removed or drilled vent holes in the covers and ended the problem. The larger ones need big heat sinks. The engineering was poor.

If you look at the detailed specifications for LED bulbs you may sometimes be astonished to see a power factor as low as 0.5 being quoted. That suggests a lot of components screwing up your power supply. Being diodes, they need either a DC supply or at least a rectified current plus some smoothing capacitors to avoid a flickery output. These are the components that tend to fail. Here’s a typical circuit:

My early LEDS had a high failure rate. As I replaced them they started lasting longer.
Warm white is a very nice color. You can even get them redder than that if you like.

I think there are new chipsets and reference designs out there in china that are making them pretty good.

Richard ==> I was fan of the 4 watt nightlight bulbs, but now find them too bright! I now buy the same nightlight fixture (looks the same) but with a single LED, which is also too bright but uses 1/8th of the negligible electricity. I paint the backside/inside of the nightlight lens so the light only reflects off the wall. Seems more suitable.

They may not last as long as promised, but they last longer than the incandescent bulbs did, and use 1/10th the power.

Also, don’t get 3000K bulbs, get the 2700K bulbs. Gets rid of the blue effect.

Electricity production in summer is usually less a problem than in winter. If an incandescent bulb produces more “waste” heat, it will do so and reduce the load on the heating system. Same thing for a “less efficient” fridge. A heat pump water heater or wash machine or tumbler will save some energy during summertime, but not in winter, since the heat it takes from the air in the room will have to be compensated by the heating system. One has to consider the “system house” as a whole, which is not being done by appliance producers or politicians.

One neat observation about light bulb efficiency in New Hampshire is that in winter, incandescent waste heat resulted in fewer hours of running the home’s furnace. Electricity came from efficient power plants and some from a nuke, but furnaces generally used oil, propane, or natural gas.

Therefore, CO2 emissions went up in the winter after changing to CFLs and LEDs!

So many problems with leds. But I think even worse are the new rules about electrical panels. The dual function electric breakers that I had to install to meet local Colorado codes cost five times what “regular breakers” cost and they are extremely temperamental. Smart meter, smart panel, smart new LEDs… flickering, dimming, pulsing, tripping… and the nagging feeling of dumbness on my part.

One of the circuits of our 1970-built house is aluminum. A pig-tail mitigation of switches and plugs in my area requires the installation of new electrical panels fitted out with dual fault breakers. The 100 to 200 amp panel installation resulted in breakers tripping the first night. The electrician returned next day and said it was the breakers. He warned us that the new “dual-function”, code-mandated breakers with their mili-second interruptions of thermal, arc and ground fault issues (actually three-way “protection”) were custom made for call backs and if I wanted, he would switch any or all of them back out for the “regular” breakers.

If that wasn’t enough of a catch, we then had to sign a disclaimer exonerating the electricians for the code violation and (apparently) any future problems caused by going back to the “regular” old breakers.

So… new panel mandatory; new, expensive breakers mandatory; a waiver for the electricians…

I didn’t go into this entirely blind and we needed the upgrade for our older house with its aluminum wiring. But what a can of worms consumers are having to open to accommodated the whims of experimental technology and progressive mandates.

This happened to me with GFI outlets in a kitchen remodel. They would trip if you looked at them funny. The electrician warned me about them and said to call if they were too much of a problem. A week later he replaced them all with the old-style GFIs.

Initial problems with low flow toilets an efficient dishwashers were solved, but early adapters had problems. Such as my father in law, who had the first “flush two times and then check the bowl” 1.5 gallon toilet in a new addition to his home. While my 5 gallon 1955 model at home never fails.

Greene,
You have a long path ahead of you to reach personal waste processing perfection, within yourself and in your journalism.
We know a couple, Randy and Rusty, unable to have children, who concentrated instead on input/output analysis of diet and exercise to minimise personal waste. They were both scientists who routinely produced progress charts over time.
The charts show their careful food selection lowered their daily stool weights over the first year. Replacement of bulk foods formerly used, for example, to maintain vitamin levels with vitamin capsules worked well in the second.
Half way through their third year, they reached Nirvana, with zero daily defecation. It is now two years after that. Both report that natural closure of the anus is nearly complete. They are now more comfortable on aircraft flights lasting many hours on their frequent international trips.
In your journalistic quest, you should seek out such people for interviews and images. Readers are encouraged by beautiful stories of pinnacles of success who can be emulated. You can, at the same time, start a movement by reducing a movement. No shit! Geoff S

Over the years I have converted from incandescent bulbs to LED and fluorescent bulbs when available. I have noted no disruption to sleep or my circadian rhythm. I have noticed that climbing a ladder to replace bulbs has become an activity-of-the-past.

I write this sitting in front of my computer that, as I understand, gives me many hours of blue light exposure as do all the modern automobiles with always-on LED headlights and my TV.

When the ban was coming in the UK I stocked up on incandescent lamps. I did so primarily as a protest at having the choice taken away. Also at the time the alternatives were pretty useless, particularly as they took minutes to produce full brightness.

Today I always use LED lamps. I’ve no idea what this stuff about “blue light” is. The light from LED lamps is warm and natural with no hint of blue. They’re also very efficient. I don’t delude myself into thinking I’m saving the planet. But I’ve no problem with efficient lighting, particularly as net zero has given us almost the most expensive electricity in the world.

Many thanks to Trump for giving people the right to choose, if only for Americans. And a huge thank you to JD Vance for a fantastic speech. His words about freedom of speech were music to my ears!

Before being full LED, I was already full “economic” lamps.

Now, I do hate the blue light, and it’s definitely not for you. Yet, at least around this god-forsaken place I am, LED and “economic” lights have a data sheet where the light temperature is indicated in K.

So, around this place, if you buy something marked as having a light temperature above 3400 K you will be likely to buy a blueish or even true blue light. Something I haven’t been doing for some 15 years by now, and all goes well.

(Knowing photography was useful.)

Of course I dont know what happens elsewhere, sorry.

[Edit:] Of course I’m glad to spend N x 2 W instead of N x 100 W. It shows in the bill. Also for not having to replace bulbs – some are working since 2008. And avoiding risk of fire; yes, it happened to me with a towel and two 25 W bulbs. So, I defend anyone’s right to use any form of lighting they prefer, and I’m altogether happy with warm tone 3200 K tungsten-like current LEDs.

Thanks for the information about the tungsten numbers. My wife Nancy suffers from a particular nasty form of macular degeneration, geographic atrophy. She has been advised to avoid blue to ultraviolet light. Several years ago I installed led tubes in our kitchen to replace the old flourescents. The performance of these lights has been impressive as to length of life, reliability and power savings. But they do look blueish, and I am about to replace them with warmer valued lights.

I have read up on the different LED lights and by checking on packages have gotten ones that are not the blue demons everyone hates so much. In particular I have installed several available at Lowe’s, their Project Source 13 inch diameter flush mount light, they have 5 light level settings from 2700K to 6500K. I have found the 2 and 3 settings work out best, although the highest setting is not bad, just really bright. Also have found “bulb” LEDs for older lamps and ceiling fans which are nice. None of the ones I am now using have the flicker effect earlier types had. On the obverse of this coin I have a PILE of incandescent bulbs, when this ban crap first started being bandied about we bought while still cheap, so have enough for years.

February 15, 2025 4:29 am

I’m all for incandescent bulbs. Fact is many applications cannot accommodate LED etc ones. And in colder climates their waste heat is actually beneficial for room heating. However do not jump on the hurrah bandwagon just yet. Manufacturers have closed and dismantled and likely sold the equipment for scrap used to make them. So a humongous infrastructure for making them is no longer in existence. Some of which was assembled over the span of decades or even a century. So flipping a switch and expecting makers of incandescent lamps to ramp up again is likely not going to happen anytime soon, nor will they again be inexpensive as all that new equipment needs to be paid for again at 10-100x more than it cost to make the production lines decades or a century ago.

Duane
February 15, 2025 5:08 am

The author repeats the fallacy that LED space lighting emits too much blue light to harmful effect. Sorry, but you can purchase any color temperature lighting you want in widely available LED space lighting products, from warm (<3000K) to very cool white (>5000K). And in recent years consumer LED lamps have been equipped with color controls that operate thru a remote to get precisely the light color you want. I have such lamps in my home, and they are cheap to buy and last effectively forever, are nearly indestructible, and use a LOT less electricity (what kind of person wants to spend more than needed on their electric bill???).

The blue light that worries some researchers comes not from LED room lighting, but from our ubiquitous computer, mobile device, and TV screens.

As for water efficiency standards, there is, just like with every other product, good design and bad design. High efficiency does not mean bad design. Water conservation may not be a big issue for the author, but it is where I live in densely populated Florida where we are on permanent water use restrictions, as well as the entire western half of the US, especially the southwest.

My dishwasher, just a couple of years old and relatively cheap, does a great job using just a 1- hour cycle, and the heater dries the dishes just fine. If you run a three hour cycle you are wasting wear and tear on the machine, and electricity and water too.

Only partly true. The nominal colour temperature of most LED lighting is adjusted through the ratio of narrow spectrum blue emitters and broad spectrum amber emitters. It tends not to be a good match for a black body spectrum at the nominal colour temperature, and is often deficient in green and red wavelengths. Here’s a typical example:

comment image

Phosphor film and resin-embedded solutions are the dominant method of warming the naturally cool light of an LED chip to more closely mimic white light. This adjusts the Kelvin temperature of the light into the warmer range, but the LED is still missing many wavelengths of the white light spectrum. Both the low cost of this technology and the general adequacy of the light color make this invention the most commonly used in manufacturing LED bulbs. Multiple LED chip solutions combine three or more individual LED chips of different colors into one multi-chromatic bulb and blend their output to replicate white light. Newer bulbs that permit users to adjust the color temperature of a multi-chip LED bulb generally entail maximizing or minimizing the output of a warm-white converted chip and a second cool-white converted chip, but the spectrum of wavelengths emitted is still limited to the spectral emission of the two embedded chips. The most successful attempts with this process have used six or more different LED chips, each emitting a different wavelength of light, in order to more closely approximate natural light. This can be a more effective, but much more expensive solution to creating LED white light. Hybrid of using both multiple phosphors and multiple chips involves marrying these two partially successful techniques into one bulb.

That’s why genuine high CRI lighting , for example for film studio use, is expensive. Spectrum wise it is at least a great improvement on CFL phosphors. When I moved in the bulbs left behind were CFL: they had to go!

4 years ago I purchased a box of 6 amazon bulbs to replace a failed incandescent bulb I still have 5 left. Blue light??? most white leds are blue chip but then there is a fluorescent silicone layer over the top which the blue light triggers into producing a good representation of white (there are expensive leds that produce a colour rendition index of greater than 90 but most are in the 80s). The blue light is severely attenuated but less so if you get daylight bulbs. This spectrum (using a transparent dvd) shows the result from a cheap warm white bulb. I do not see a massive amount of blue !! If the uk had some sun I would get its spectrum!

i am not to concerned with blue light exposure.
i am more interested with the right amount and color temp for specific areas of my home.
our kitchen, dining room and living room share an open space.
12’x12′ kitchen has 9 recess cans with a 75watt equivalent led at 4kc/t. plus an independent centered surface fixture with 3- 60watt led at 3kc/t.
dining room has 4 recess cans with 75watt led at about 3kc/t on a dimmer.
15’x20′ living room (high ceiling) has 8 cans 100watt eq. led at 3.5kc/t with dimmer. plus a couple of small floor lamps.

I have found that mixing high and low color temperature in the same space makes it easy on the eyes.

this graphic will get you in the ball park.

I acquired a high-efficiency washing machine in 2018. If I want clean clothes, I must use the “deep fill” setting as the water-efficient settings don’t work.

“LED bulbs have been a standard replacement for the incandescent bulbs. There is myriad of reasons to deride the blue light that LED bulbs emit.”

“Personally, I am planning to load up on the incandescent bulbs as soon as they become available.”

Be my guest. Personally, while I intensely [weak pun there] disliked compact fluorescent lights, I very much liked high CRI (Color Rendition Index) 2700K LED bulbs from CREE. It appears that CREE just wanted to make the LEDs but made some bulbs in part to get other manufacturers to like their LEDs. I can’t find their oldish A19 style bulbs that were designed for enclosed fixtures for 2700K, just 5000K. Bummer.

Of course, white LEDs are a combination of a blue LED and yellow emitting phosphor. Nearly all of the blue light gets absorbed by the phosphor. I don’t know how the CRI levels are achieved, they may use multiple phosphors or dyes. 2700K doesn’t release much blue light.

BTW, I used to live in a house where the kitchen/dining area had 14 recessed flood lamps. As incandescent bulb manufacture moved to China, incandescent bulbs lost a lot of longevity and I started replacing those with CFLs, then got an early CREE LED bulb to put over the stove, as early CFLs made egg yolks look remarkably pale. Then the Chinese CFLs start having early failure issues and I replaced a few under warranty, and a couple more that didn’t have a warranty but died within a month – the seller honored my letter documenting the installation date (I had started writing that on the bulbs when I installed them).

When you stock up on new incandescents, write the installation date on them or nearby if the heat destroys the ink. You may be disappointed.

(I had started writing that on the bulbs when I installed them).

I do this also. Several of the CFL (swirly) flood lights I replaced after an electric panel upgrade were more than 10 years old. Some were so burned-through at the base that the ceramic fixture was loose. The still-funcioning light elements were flopping back and forth inside the bulb. Still ticking.

RE: incandescent. It seems these bulbs will always be around as utility bulbs for heat situations. My sense is that they must be tougher than any other bulb to handle temps inside a 500 degree oven. Incandescent utility bulbs seem to last longer in various settings **, including freezer and fridge and these locations necessitate great shock resistance too since they are being jarred fairly frequently.

** AI searches tell me I am wrong.

Wonder what NASA uses on the exterior of the space station? Do LEDs hold up under extreme cold / hot fluctuations?

Incandescent especially at low wattages and high voltages (230V) are extremely fragile.
12V 60W halogen filled emitters are about as good as it gets, but they are a bit ‘blue’

The only place incandescent are indicated is in e.g. a cooker where the bulb is inside a 450°F oven…

I stocked up on incandescent as well when Canada banned them. However, advancements in LED have meant that I have used very few of them. I am sitting under a desk lamp that can be switched to a soft reddish light at the touch of a switch. My dining room chandelier has all soft white LED bulbs. My kitchen has powerful blue LED lights that I need to see well with aging eyes. Ditto for my garage and workshop. Banning incandescent was ridiculous and unnecessary as the advantages of LED meant that wide adoption was inevitable. In my experience, the advantage of a long lifespan is not as great as was touted, though they have become inexpensive enough that it doesn’t matter much. Current LED bulbs for residential use are much improved over what was originally available.

Same. I hate CFLs and those were the “standard” replacements for Incandescent back in the day. As soon as they started talking about banning 100w bulbs, Every time I was in a store that sold them, I’d buy a pack. Then after 100’s were gone, I started buying 60’s, then 40’s.

I used them for a while when LEDs were too expensive…I refused to buy CFLs…but as soon as the prices on LED came down enough to be worthwhile I started buying them and haven’t looked back. I rarely have to change light bulbs anymore…used to be a weekly task. There seemed to always be a bulb or two out somewhere in the house. Not any more. But that means I’ve got a lifetime supply of incandescent bulbs on hand if I ever need them.

I haven’t decided to get rid of my stockpile yet…they may still come in useful someday…but right now they’re just taking up space in the attic.

Yes, the flicker from CFL bulbs was annoying.

6 ceiling can flood lights in my kitchen. Dead incandescent bulbs were replaced one every other month. Switched to LED and only one has been replaced in 10 years and the kitchen heat has been reduced. The LED bulbs paid for themselves in one year. Converted most of my remaining bulbs to LED and none of those have failed and my electric bill reduced another 15%. Overall, with efficient appliances (that’s all you can buy now) and bulbs my electricity use has gone down 40% since I first moved in 43 years ago but my electricity bill has increased over 200%. You have to be careful about color when buying. I saw LED bulbs available now that have consumer adjustable color settings. Count me as a fan of LED bulbs but not a proponent of forcing you to buy them.

I bought an entire case of 100w bulbs years ago, They will last longer than I will be alive.

You better calculate how many $ of electricity that case of 100 W incandescent bulbs will cost you compared to say slightly more expensive 2700 K LEDs that consume 14 watts, last years longer, and don’t add much to your AC load.

LED light bulbs don’t work with light dimmer switches. These mandated lights flicker continuously if used in a light fixture with a dimmer switch. Ridiculous.

Some work pretty well. There’s an issue with some dimmer switches, and there’s some odd behavior with my dimmer-compatible CREE LED bulbs in two bulb fixtures that vary whether one or two bulbs are installed.

In the future there could be some inexpensive dimmer/bulb designs that could work very well. Don’t write them off yet – most dimmer switches were designed for incandescent use and LED bulbs were designed to run at full power no matter what the input voltage and current waveform looks like.

The LED bulbs usually say on the packaging whether or not they are dimmable.

LED’s can dim very well, but it takes a different dimmer control circuit. Incandescent bulbs were dimmed by reducing the voltage. LED’s must be dimmed by reducing the current while keeping the voltage nearly constant.
