the upside and downside of low-energy lighting

by:Grade     2020-01-22
In this world, 2 billion people are still squinted by the light of the kerosene lamp (at best)
In the evening, any kind of electrical lighting is an immeasurable gift.
But experts say that as long as coal is a big source of electricity, finding efficient, cheap, and usable alternatives to incandescent lamps will be a vital business.
Julie skerver, a reporter for The Times, tried to end an article exploring people\'s experiences with next.
Generation Lighting-
Compact fluorescent lamps, LEDs, Optical tubes, etc. —
From homeowners and business owners to interior designers, builders and architects.
She needs your help.
She said that the article will examine to a certain extent whether the various proposals to ban incandescent lamps have allowed designers to accept CFLs and other more efficient forms of lighting.
But she also \"wondered if there were civilians who switched not only in the laundry and garage, but also in their own home (
Mood is not a problem)
But in living spaces like kitchen, library, TV room and bedroom.
She asked you to send contacts, comments and anecdotes to jscelfo @ nytimes. com.
Of course, I ask you to post them here as well!
I started with my own experience.
We replaced almost all of our bulbs with CFLs, although this is not the case with dimmable fixtures.
We bought some theoretically dimmable CFLs a few years ago, but it quickly burned out.
It still seems to be an obstacle.
Have you overcome it? [
Update: The reliability of the bulb has also changed a lot, and some CFLs burn very fast.
When I installed, I had already started marking their dates using Sharpie to check how long they were already there at the time of death.
Does anyone else have this problem? ]
The Times reports several elements of the energy lighting challenge
Limited world, including an overview here and CFL promoted here by Wal-Mart.
Comments are no longer accepted.
We have replaced many bulbs at home with CFLs.
They will be fine once they open for a while.
However, it will take a while for them to reach full brightness, and it is a big hassle if you want to turn on the lights in a dark corridor for a while.
How about a \"hybrid\" bulb like a hybrid car?
A combined fixture with an incandescent lamp, it lights up immediately, but it turns off once the CFL reaches full light.
Five years ago I replaced all the bulbs in my home with CFLs due to economic problems and the corresponding need to reduce utility bills, and I\'m glad I did.
I have a white CFL in a place like the kitchen and it does a good job.
I prefer soft yellow light in other rooms.
I have never used one that can be darkened.
In these 5 years, I think only 3 bulbs have burned out.
I must say that, in my opinion, at this time in history, this is the first height when we should think about how to reduce our energy use to an absolute minimum --
The world is arrogant that anyone has the right to use more energy just to create a \"mood\" at home.
Mercury from fluorescent bulbs is another panic waiting to happen.
How about the deposit-and-
Those return systems?
At our home, we have done our best to switch to CFLs and are pleased with the results so far.
In the fixture of the bulb without a lid, we are using Ikea products that look like a traditional incandescent lamp, but it is the CFL included in the frosted plastic cover.
The eyes are much easier than the \"exposed\" CFLs.
From Lao, we are using a spiral shape of 3-
The light in our living room is CFL.
In the bathroom, we used the spiral CFLs we purchased at Costco.
So far, we are satisfied with the light quality of the CFLs we use, and as we have already pointed out, buy the CFLs for light that emits light with very similar spectra to incandescent lamps.
We have two ceiling fans with light fixtures and when they are connected to the dimmer switch, we did not convert to CFLs, nor did we find any \"dimmer switch compatible with CFLs \".
I want to find some.
I live in Mexico City, where the electricity bill in the family budget can be large.
Low-energy bulbs have become very common in middle-class and lower-class families.
No one invited me into the upper class, good luck to you.
I think it should be
Scelfo just started her story on CFLs.
She will definitely find that all the color temperature is available today so you can see the cool light in the garage and the warm light in the living room.
I don\'t think CFLs is the \"next generation\" lighting.
We have been using it for several years.
I am now waiting for the price of LED lighting to become more affordable-this will be the next generation of lighting.
Ever since CFL was brand new I have stayed with them
Because I am not on the Internet, their energy saving is very good. But.
There is a potential problem, that isblogspot.
The Html CFL section is at the bottom of the post
Basically, there is growing anecdotal evidence that some CFL may seriously interfere with the production and metabolism of melatonin, resulting in insomnia (
We have a prevalence of insomnia if you don\'t know. )
This is the color temperature is high, there are a lot of blue in the spectrum.
Yes, this is an anecdote.
But these anecdotes are exactly the same as the known science.
Remember, science begins with anecdotes.
When I got rid of my old bedside CFL-I was able to sleep without medication for the first time in 15 years.
Because I put that light in.
That was a few months ago.
I\'m still sleeping.
In addition to the bulbs in the restaurant equipment, we have replaced each bulb in the home with CFLs (
It carries a faint flame.
Light bulb in shape, I haven\'t found CFLs yet).
Although they take a few seconds to turn on, they provide enough light once they are fully lit.
We even removed four bulbs from the chandelier in the foyer because one of them did that.
I don\'t see any reason not to switch.
We recently built a new house with a traditional fluorescent installation in two bedrooms and our home office.
Most of our remaining lighting is made up of recessed jars.
As the existing bulbs run out, we will replace them with the CFL.
We use CFL on all the fixtures and dressers.
My only complaint is the color of the light.
In some cases it has a definite green casting and in others it has a very yellow casting.
I told the people using the guest bathroom half jokingly that they were not biased, just light.
\"Cool White\" or \"daylight\" in one brand may not match similar descriptions in another brand.
All brands have a common standard, maybe Kelvin degrees, which will be useful.
This seems to be primarily a problem with CFL, not with standard fluorescent lamps.
Not long ago we replaced all the bulbs with CFs.
There was no dimmable light bulb at the time, so I simply took out a dimmer switch at home.
The bulb gradually became better over time.
The oldest in the House also takes a few seconds to turn on the lights and send out a rather sad color, but the latest bulb is awesome! !
They are very bright, come on right away, without the disgusting fluorescent color I had associated with the basement and the office, and not for all my old installations.
I also use LED lights on my bike, which is a great improvement over the brightness of traditional bulbs.
Of course, there are almost no light bulbs burning out in our house-I never realized how annoying it is.
It\'s also good that they put less heat in the summer (heck-
Even in winter.
I haven\'t burned my hands on the bulb for years! ).
We have replaced about half of the bulbs with CFLs.
So far, the results have been mixed.
Some are advertised, but we are much earlier than we should be \"theoretically.
I find this a problem considering the cost difference.
I have to agree with those who point out the warmth
Time and color are hard to adapt.
Different color temperature bulbs seem to produce different strange colors.
I think we will eventually get used to these things, but I really need to see better reliability in terms of how long they last.
With the exception of two, we have replaced all the bulbs with the CFL-we can\'t seem to find a CFL brand, which is in the same shape as the garage door opener expected, so this is the incandescent lamp we have left, we had a halogen lamp in our living room and it kept going so we didn\'t replace it.
We didn\'t throw away the effective bulbs, we just replaced them one by one when they expired, and the old ones won\'t take long.
I believe that in the years we have now, only two of our new CFL have to be replaced;
They will definitely last longer.
We also had a problem with the dimmer switch, so use the normal on-
Turn off the switch-we rarely use the old dimmer, and there are other things besides turning on --
Switch off anyway.
We old. for a long time
Tube fluorescent lights are installed on the ceiling of the garage, kitchen and another room.
The embedded lighting in the home/TV room and one bedroom is easy to switch to the CFL, the ceiling fixtures in several rooms are not suitable for the older larger CFL, but the small company that came out a few years ago worked well.
The rest of our lights are in the table lamp and all of them are suitable for the new small CFL.
A few years ago, we changed our Christmas lights to LED.
When we buy most of the CFL, our local power company subsidizes half the price, so we can definitely save money without replacing the bulb, not to mention a drop in electricity usage.
I think the CF bulb is great-I have replaced my 95% bulb effortlessly.
I will respond to some other posts.
Steve Mercury is not a big problem.
You can prevent more mercury from being released from coal by using the CF bulbs contained in the bulbs.
If you are still not feeling well, treat them with hazardous waste.
Greenpa-I am a doctor with seasonal emotional disorder and I use CF bulbs completely at home.
Any light can inhibit the production of melatonin-all-optical spectrum light like CF may do more than incandescent lamps, but the key is that any light can do it-especially strong light.
Basically, you should not use any bright lights at night if you suffer from insomnia.
I have a 3 W CF light (a ‘baby’ bulb)
For this reason, by my bed.
When you want to affect melatonin suppression, I used a whole bright CF bulb in am.
Nick-CF bulbs advertise on \"degress kelin.
Just go/www. nolico. com (
A good website for CF bulbs)
You can buy the light of Kelvin 2700 (Like incandcent)
Or 5000 Kelvin (
More like the sun.
There is also something called CRI or \"color reproduction index\"-the higher the better.
Things with higher CRI should not have so many strange tones.
The CRI of the newer \"three phosphorus\" CF lamp may be as high as 90 (
This is good for those who complain about green Hughes. )
Also don\'t forget that although CF is much more efficient than incandescent lamps, the efficiency of low pressure sodium steam lamps is more than twice that of CF lamps-but they are very slow, and there are terrible CRI-so they only work outside when you like to play basketball.
Most street lights use this.
Todd rabaski uses CFLs in very limited cases.
We use some lights on the timer so that we don\'t have to turn on the lights in our living and family rooms or stumble to find the switch.
This is a bulb of 6 W and 13 W with incandescent equivalent of 25 to 60 W.
I used 23 watts of CFLs in our porch light, which is equivalent to 100 watts.
Problems with CFLs: 1)
Mercury-as CFLs become more popular, this defect will have an increasing impact on the fan
Disposal-see point 1;
These are hazardous materials and are therefore regulated-you cannot deal with them (legally)
In a normal trash can.
Vulnerability-see point 2 and point 1;
The glass in many CFLs is very thin, and the storage, use and disposability are compromised;
In some cases, they are as fragile as the old ones
Decorate the shape of the Christmas tree
DIMMABILITY-also suitable for electronic controls (such as light switches controlled by radio), most fluorescent lamps are not compatible with these energy-saving controls
Color temperature-this is a small problem in my book, but it\'s more important for some people. Yes, so call me when LED fixtures are as common as CFLs.
I have 2 ceiling fans with Globe at the bottom and I haven\'t found CFLs small enough so they still have incandescent lights (
However, the one in the kitchen was burnt out).
Some of my people seem to be coming right away, some take a while to really light up, and I do find it a bit annoying.
I\'m still looking for a yellow color small enough to fit in my porch light fixture-I have a white CFL now and it\'s a full-
Night buffet of gecko.
I really didn\'t notice the color of the lights-none of my rooms had white walls or floors.
They collect dust in open fixtures, but I don\'t mind how they look.
I have halogen lights in my sports-
Detection lights outside-not sure there will be any CFLs in these fixtures, although I think I should take a look at it again, as it must be painful to replace the bulb at the top of the roof.
I had a virtual full conversion of CFLs in 2001 and had some observations: 1.
Finding CFLs that fit certain lights can be a big challenge, especially if you need highlight output to read.
On some desk lamps, I had to replace the wire harp supporting the lampshade to install the bulb. 2.
By selecting the CFLs with a \"warm\" light output, you can avoid standard complaints that are too harsh and unpleasant to light. 3.
I learned that CFLs is not a good choice for places that no longer use CFLs (
> Stretch for 20 minutes at a time).
Cycling often burns the electrodes prematurely, usually before you save enough power to cover the extra cost.
I have replaced the CFLs with a low level
Wattage incandescent lamps in these applications. 4.
Unless specifically labeled for this purpose, CFLs do not do well in embedded and closed devices where heat may accumulate.
Before giving up, I burned many expensive GE Genura CFLs in the ceiling fixtures and replaced them at least twice during the warranty period. 5.
Find app-
Specific CFLs may be a challenge in retail stores, and in the same store, the choice may vary depending on the range over a few years.
For example, Home Depot now has a lot less CFL types than it was six years ago.
Online retailers often offer better options at better prices. 6.
During that time, I saved a lot of money by switching to CFLs.
I \'ve made other changes to my electricity usage at the same time, so it\'s hard to figure out how much.
Before changing the car, I used about 5300 KW hours in a year;
I used about 3000 KW hours in 2006, or reduced it by more than 40%.
The average annual electricity consumption of American households is about 11,000 KW hours, so I use about a quarter of the national average.
I don\'t think my way of life has been seriously affected.
I have replaced most of our light bulbs with CFLs.
I bought all kinds of bulbs and tested them in different places.
We loved the access to the living room, bedroom and bathroom, other access to the basement or outdoors.
In the brand we like, we find a brand (
Color temperature 2700 K)
Looks best near brick and wood, while the other one (3000K)
Looks best near limestone tiles.
We don\'t like cool white (3500K)or daylight (5000K)for indoor use.
We have some bartenders.
23 W âx80x93 85 W equivalent)
It doesn\'t matter, but they are not as dim as incandescent lamps, and dim without changing the color, which makes incandescent lamps warmer as dim as compared to incandescent lamps.
In order to avoid the problem of initial dim light for short use (e. g.
Go to the kitchen for snacks)
We\'re a little overdone in that area.
The spiral has the highest efficiency, the lighting speed is faster, and the closed spiral (reflectors)
I have tried to provide less light for the wattage and light up more slowly.
In the insert lamp, the reflector looks a little better, but the spiral performs better and is barely noticeable unless carefully observed.
Some bulbs burn out very quickly, but most of them continue.
Home Depot brand (
Non-commercial electric vehiclesdimmable)
Excellent color balance, low price in multiple colorspacks.
The color balance between Satco and Greenlite is very good (
Like incandescent lamp)
But it\'s hard to find them in-line.
Almost all my lights have been replaced with CFLs.
There is no problem other than that you can almost pass through my bedroom at the time the light lights up, which means a couple of thick and short toes.
The quality of the lamp is very good, especially at the back of the lampshade.
As for the disposition issues, I was told that they are not worse than the normal mess.
The problem with flower lighting is that the bulb contains mercury.
Mercury is finally filled in the land.
I\'m waiting for LED lighting.
Andrew, I can understand your frustration with all the changes in CFLs. Energy-
Energy-saving bulbs of all shapes and sizes are now available.
That\'s why environmental protection creates a guide to help you choose energy.

For those who care about Mercury, I would like to recommend our climat11 11 blog, \"risk of mercury in CFLs: Facts \".
2/John Balbus, chief health officer for environmental protection, explained these risks and concluded that they remain the most eco-friendly option.
If you\'re not sure yet, I suggest you read another climat11 blog, \"Why switch to compact fluorescent lights?
On the environmental protection blog.
Org/climate411/2007/03/06/bulb/it contains so much useful information that it will convince anyone to switch to CFLs!
I used CFL everywhere at home before, but last year I decided to replace all the old incandescent lamps with CFL.
Great changes have taken place in the kitchen and garage, I have four T-
12 ballasts and five t-in the kitchen-
There are 12 ballasts in the garage.
I replaced the lights in the kitchen with two hanging lights from CFL and replaced the garage with two embedded lamps from CFL.
In addition, each of the three bathrooms in my home has a 4 to 8 light fixture.
I decided to use 2 or 3 high wattage CFL instead of 4 or more.
I saw the difference in my electricity bill (
Consumption is reduced by about 30%).
Nothing is perfect, however, and as many of us know, most CFL contains mercury and may not be used with dimmers.
On the one hand, they may be better, because they have a long life span and therefore reduce production, which reduces waste like incandescent lamps.
But they may not be easy to recycle, and if the CFL is destroyed, we are not sure how dangerous mercury is for our health.
But the difference is not big LED.
They are also made of chemicals that pose a risk to health when they are treated, burned, etc.
If we involve electrical engineers, chemical engineers, environmental engineers and international standards organizations in new designs, there should be solutions to these problems.
I work in a Design & Construction Company and now I\'m starting to be cold
Cathode Fluorescent bulbs for most of my recessed lighting applications.
The Ccfl bulb is fully dimmable and is ideal for 6-inch embedded lighting (
At present, they have only one standard. 38 available)
Apparently it will last 25,000 hours.
Each of them costs between $18 and $20 and is sold through architects near Washington (
For more information:/www. betterbulb. com/).
The color temperature of the bulb is also very good and does not flash.
It seems to me to be a good bridge between the standard cfl and the led bulb, which is still a bit too expensive for most people.
What the Cfl bulbs are generally not known is that their ballasts may or may not be suitable for installation in upside down applications (
Like a recessed shell)
At different temperatures
They are likely to lose efficiency and run out of energy faster than expected.
My other observation isyes-all)
Residential electricians I work with don\'t like to use cfl bulbs and prefer to be provided by the owner.
It seems that due to the difference in quality, when the callback runs out or breaks, they spend more time on the callback.
I hope that one day this concept will change because the quality will definitely change.
I have replaced all our incandescent lamps with CFLs.
No, the quality of the light is not ideal, you can hear a slight hum in some places.
But, it\'s hard for me to tell my child that I haven\'t done much to mitigate climate change for aesthetic reasons.
The best thing a person can do for the environment is turn off the lights when they are not in use.
Turn on the lights only when you really need them.
Most people\'s homes are lit up like Christmas trees.
Some people even feel the need to light up the block.
This absurd behavior often takes security as an excuse.
While CFL and other technologies can help, they also have shortcomings.
There is no real free lunch you can pay in other ways --toxicity, etc. .
What people need to do is learn to save rather than consume.
That\'s simple.
Replacing all your very good working bulbs with CFL is just another act of blind consumption and waste.
We have replaced all the bulbs at home with CFL and LED.
We had to look for some, but we did find some bulbs with covers for our \"Candra\" type lights, ceiling fans and bulbs used in restricted shadows.
We do have a bright (
100 wattage)
The bulb in our main bathroom is located in the fan/heater/light fixture.
The first bulb we tried was not as bright as it was shown on the package, making a low hum.
Especially in the bathtub, which is crazy for us.
So we changed the brand, Sylvania-
We have been happy since then.
Most of our CFL is Sylvania and we are happy to be able to get a \"warm white\" bulb that is aligned with our interior.
In fact, in our large room, the kitchen island lights use 3 CFL, 15 feet away, and our dimmable meal lights use 5 incandescent lamps.
The quality of light is difficult to distinguish.
Despite the cold weather, we were lucky to use the CFL outdoors (
Colorado Mountains).
The only downside for them is that they need some time to warm up and get to the full level of lighting.
I will share with you the story of a \"green building.
Our friend has just built a green home in Denver, and although the builder did make a major environmental upgrade to the building housing and materials, he seems reluctant to include energy-efficient lighting in his design
This is not even an option!
My friend had to give away and replace about 60 incandescent lamps for the CFL they wanted. Pity!
