led lighting gaining acceptance (sort of)
Eventually, it will become the preferred technology for many lighting applications.
As I pointed out in an article about the commercial use of LED lighting in today\'s green Special sector business, lighting designers who were cautious about recommending LED products only a year ago are now more confident in doing so.
This is partly due to the DOE-LED action to develop an Energy Star Guide for the next generation of lighting to convince consumers and enterprise LED products to operate as claimed.
However, this is also due to improvements in the lighting itself.
LED lights are becoming more efficient, producing warmer, more attractive colors at higher brightness levels.
On Tuesday I saw a new backlight from Nexxus Lighting, similar to the one installed on many kitchen and office ceilings, which gave warm, pleasant light
It weighs about 1-
The third of the competing lights, using 8 watts to produce 50 watts of lightwatt bulb.
But how many families and businesses are 50-watt lamps?
When the industry started to produce 75-and 100-
The Led will start to gain traction. (
Lighting Company Cree has announced an anti-beam light that says it produces a similar look to halogen lamps, using 12 watts and can replace up to 90 watts
Incandescent lamps. )
Are the LED lights ready for consumers? Hardly.
The most strange thing is
LED products sold in home improvement stores are still below standard.
Many manufacturers have made unproven claims about the life and brightness of the lamp.
But for the well-
Heeled set, there are a lot of highly respected products that use a fraction of the power of incandescent lamps.
But their initial price is high.
I recently visited a house in the tony Brentwood district of Los Angeles, which is full of LED \"downlights\" made by Kerry, and I can\'t tell the difference between these lamps and standard bulbs.
The inventor of the Segway scooter, Dean Carmen, only lights up the house he owns on the island with color dynamics LED products.
DOE will hold a workshop in a few weeks to discuss the status of LED lights that can replace standard incandescent lamps.
More commercial buildings, including a building in the Pentagon and even the KFC/Taco Bell restaurant, have turned to new technologies.
However, despite these successes, many engineers still have resistance to the use of LEDs.
A major real estate developer in Los Angeles recently showed me letters from his engineering team asking why people with his normal mind would use LED lights in business projects, use high costs as a reason to avoid using them.
For now, it seems that the lighting industry and the construction industry often speak different languages.
Comments are no longer accepted.
It\'s just a matter of time.
Taiwanese companies are spending a lot of money to produce better and cheaper LED lighting products. (
By the way, I can\'t believe your copywriting editor made you write LED instead of L. E. D. )
All lighting should be evaluated on a TCO basis.
For lighting, the equation is: TCO = the initial cost of power over the lifetime of the \"bulb\" of the replacement bulb, which is why the first large-scale application of LED lighting is for traffic lights.
The labor cost of replacement is huge (
Professional Truck, crew, length of time on site).
There are two problems with family use: 1.
Labor costs are usually $ zero.
The homeowner thinks his time is $ zero and the lights are physically easy to replace. 2.
Homeowners have a very poor ability to calculate energy costs over the past decade, so they tend to spend energy costs at nearly zero prices.
Once the cost of the LEDs is 3 times rather than 7 times, we will see that the homeowner\'s absorption will be much larger.
Developers will always use the technology at a lower initial cost and a higher life cycle cost.
This is simple economics.
But our society does not allow developers to build unsafe buildings, nor should we allow them to build unsafe buildings.
Since volume ramp upCFLs is a health hazard-Mercury, which is a safety hazard due to low initial lumen, the use of residential usel should be banned. e. d.
A traffic light was installed in Portland, Oregon, to further push Portland into any cost-saving energy during the first heavy snow, and most traffic lights went off!
Our best minds have finally decided. e. d.
The heat is not enough to melt ice and snow from the lens.
But we will be fine until next winter. .
I think people need to start buying now.
The initial price is well worth it for many reasons, including the absence of mercury inside them (
Different from compact fluorescent lamps).
Low power and long life are another reason (
Less power consumption and less landfill).
In addition, your contribution (
Admittedly, in a small way)
As demand increases, everyone\'s price will drop.
There is the same logic in buying organic cotton.
LED lights for the lede molecule!
Do you mean \"warm\" light to the ugly yellow tone from incandescent lamps?
First of all, the color made of compact fluorescent lights so that I can have white light?
I don\'t know why you want that horrible effect. As an aside, L. E. D.
Lighting has made great progress in professional film and video applications.
They are getting brighter, cheaper and have no heat.
I just came back from the NAB meeting and was shocked by the changes last year.
Two suppliers stand out: Litepanels/www. s131567196. onlinehome.
Com/servlet/StoreFrontI suspects that the same technology will make progress in the business premises.
Please stop complaining about mercury in compact fluorescent bulbs.
The amount of one minute.
For God\'s sake, find something to worry about.
Swine flu is a candidate.
Donovan Jacobs, all Portland has to do is turn the hood back on (
They shouldn\'t be taken away in the first place)as the older-
The style of traffic lights.
I am by no means a \"green hardline \". ’Mandate LEDs?
While I sympathize with the intent, managing a particular solution is almost always a bad idea.
Instead, a certain * Performance * is required and any solution that meets that goal is allowed.
In this case, a suitable lumen/Watt is required and some time may be includedto-full-
Light and spectral reference.
If some smart companies can produce the same light as a 100 W incandescent lamp with 0.
By using rotational polarization, the casimir phase doohickey quantitatively analyzes why we want a law that requires only LEDs?
LED bulbs are better than CFL spiral fluorescent lamps because: 1)
They lasted 10 times before \"burning (
Dimming to half brightness)2)
They do not release or destroy Mercury.
They have a little less energy than CFL and a lot less energy than ordinary incandescent lamps.
On the other hand, the price of the LED bulb is 50 times that of the CFL, which is actually $50. $1.
At this price, the only reason is to save expensive or dangerous labor, such as having union employees climb the ladder to replace the light bulb.
For ordinary home lighting, the conversion from incandescent lamps to fluorescent lamps can be realized in one month, and hundreds of dollars can be saved every year.
Instead, switching to the LED can actually save all the cost and provide it to the manufacturer of the LED bulb.
LED bulbs do pay for themselves for long enough, but if your goal is to save money, the right choice for today is CFL.
Costco has started selling LED floodlights and chandelier bulbs at a low price.
$11 2 internal 50 W floods, $14 2 external floods, or 3 45 W floods
A small base in Watt for $12.
There is no medium base yet.
I switched because the place I stayed was only 100amp service and no gas. (
I also reduced the size of the microwave so I don\'t have to turn off the halogen lights or air conditioning in the bathroom to use it. )
I have tried the CFL external floods but they are not working well, the humidity kills them and does not work in cold weather.
The flood of LED is good.
I have been putting small LED lights (
A set of 4 1 watt)
You can see 24/7 of the floor from below Ikea\'s shelves and above the cabinets.
It was very pleasant to get up at night.
Why did the compact fluorescent 50/100/150 s I bought not look as bright as the incandescent lamp they replaced? BUTBUTBUT….
Looks or feels inferior to incandescent lamps. Really don’t.
I\'m glad to see that some of the clever box stores have risen to the present and do carry L. E. D. products.
I \'ve been looking for, and so far I \'ve been frustrated with the need to get these products online at a high cost.
I don\'t mind being an early adopter either, but it would be great if more box stores could join the project and the cfl would disappear in the background they belong, like a bridge in the distance.
Andrew delanoreders should know that the technology behind Nexxus\'s high quality products is driven by quantum dots from QD Vision, Inc.
Quantum dots with luminous properties are ideal for low power solids
National lighting applications are increasingly the basis for products that provide better color and power efficiency.
This technology will bring incandescent color quality for the first time for efficient LED lighting solutions.
The whole \"warm light\" and \"Cold light\" are meaningless marketing nonsense.
The sun is very, very hot from Fusion (
But there is still a long way to go).
The \"warm light\" comes from an incandescent lamp, which is hot enough to slowly boil the tungsten atom from the filament.
\"Cold Light\" seems to refer to light emitted by fluorescent bulbs closer to the sun than incandescent lamps.
If you want a \"warm\" LE. D.
Lamp, you can mix some red diodes in white diodes.
As far as I know, the amount of mercury in the CFL is now about 1/4 of what it used to be and is now close to 1 mg.
Also, from what I have read, in the life of an incandescent lamp, the amount of mercury in coal burned to run the bulb is 9 mg more than the CFL.
I happen to live near a coal plant and the fishing area is now contaminated with mercury from the coal plant.
RE: 15 \"I\'m glad to see that some smart box stores have risen to the present\" and the box stores sell what people want.
People are excited when C. F.
I started coming out, and then when they noticed the yellow, it was quickly turned off by them.
If the box store starts buying thousands of L. palletsE. D.
But people are not too interested, would you eat at the cost of thousands of unused LE. D. ’s?
When the light is of good quality and the homeowner sees a reason to exchange it, they do so.
Before that, let\'s be happy with the progress of technology and the rise in prices. E.

I want to thank Dave (second poster)
Because of his insight into the economic factors of builders.
I also like TCO calculations and the New York Times should keep this in mind when evaluating LEDs as well.
I think consumers can be reminded that the cost of electricity will increase in the long term.
For fluorescent lamps, the package says: Save $50 each time an incandescent lamp is replaced with this bulb.
Perhaps when they compare LEDs to fluorescent lamps, time can provide a similar calculation.
This is an easy way to compare efficiency and upfront costs.
A useful data for this discussion is: when observing incandescent lamps, people always say they are warmer . . . . . . Even whiter.
This may seem subjective, but can actually be quantified by two parameters.
1. Yellow. white vs.
Blue is \"color temperature \".
Most people think that the light yellow light is warmer and better for a family, but the light blue light is better for the office.
Part of the reason people find fluorescent tubes ugly is that they have too high color temperature.
Secondly, more importantly, the color rendering index \"(CRI).
For a given temperature like an \"average\" color, most rays are actually made up of multiple colors.
Two bulbs with the same temperature but different CRI will appear:)
It\'s the same when a person looks directly at them B)
They are different when their light reflects objects.
Humans prefer the broad spectrum because all the colors in the room are vibrant.
In fact, in CRI, the light emitted by an incandescent lamp is considered to be nearly perfect because it follows a Gaussian (bell curve)
The distribution of colors around the mean.
There are glowing materials that glow in a specific color . . . . . . That\'s all.
So, that\'s the main reason why people find fluorescent tubes ugly-low CRI makes the skin zombie and the food doesn\'t look appetizing.
Modern fluos, especially CFLs, have a wider range, often at higher cost and with a slight drop in efficiency.
There are 3 kinds of light emitting materials in old-fashioned white LEDs (R,G,B)
Nowadays, they contain yellow, purple and so on.
Street lamps use low-pressure sodium, which is as yellow as those romantic incandescent lamps . . . . . . But there\'s a CRI of 40%!
So, the next time you buy a CFL or LED bulb at Home Depot, pay attention to the CRI number.
Those over 90 years of age are preferred.
Why no one mentioned the obvious disadvantages of led?
The Led will not \"bake\" rooms with light like incandescent lamps and CFLs.
The tiny strong spotlight is fine when mounted on your forehead.
I know the LED manufacturer is trying to overcome this, but the LED will only be used for special purposes and notable effects until a reasonably priced version comes up.
The initial cost of LED lamps is definitely higher than that of CFLs (
Anywhere 5 to 8 times)
Just like CFLs are usually 6 times the cost of incandescent lamps.
But LEDs are twice as efficient as fluorescent lamps.
So to answer Chris\'s question about fast efficiency comparison, CFLs uses 20% of the energy of incandescent lamps, and the led uses half of the energy of incandescent lamps, that is, 10% of the energy.
Claims like \"save you $50\" always confuse me-what, every month? per year?
If you buy an LED bulb for $40, it will have a life of 5 times as long as $4 CFL (
Led is estimated to last 50,000 hours)
And the electricity bill is half the original, you even broke the electricity.
As for the quality of LED lights and LED products, this rule is established no matter what you buy: you get what you pay.
If you buy something in Costco or Home Depot, you will get something like this. (
If you buy Home Depot paint, you have to wear 4 pieces of paint instead of covering the old wall color with 2 coats, is it important that the cost of the paint is half? )
You wouldn\'t expect it to perform like a Porsche except for Honda Civic, would you? //www. ledsmagazine.
Com/features/2/5/4 is an article that reviews the light from the led.
People should read the facts before throwing words like CRI and \"cool\"warm whites”.
There are a few things to pay attention to about LEDs. 1. No mercury.
Although it is said that the CFL lamp has only about mg of Mercury.
Think about all the houses on your street, it\'s a lot of lights/Mercury.
None of these Mercury will be properly treated (
Come on, how many of you have handled the last CFL correctly, even DLP lights with more mercury. )
Putting the light in a brown paper bag won\'t help or add it to the recycling pile. 2.
The CRI index will have to adopt a new indicator for LEDs.
It was designed before they appeared, and with the advent of new lighting technologies like ESL, we need a better measurement system. 3.
In many cases, the light projection of the led is better.
