At light fair, the lighting industry\'s annual trade show last year, several companies are talking about their upcoming LED-
Basic alternatives to traditional bulbs.
A year later, at the New York light show this year, they are still talking about this topic.
Only this time, manufacturers are more specific about their plans.
But don\'t start planning to replace all the standard bulbs in your home with a 50,000 hour LED version.
Later this year and next year, the initial version from companies such as Lighting Science, Osram siwania and Philips will be issued equivalent to 40-
Incandescent lamps in Watt.
I think most Americans say, \"Wow! ”The last 40-
The watt light bulb I saw was in the hotel room and it was not easy to read.
I know very few people actually use 40-
The light bulb of their home60-, 75-, and 100-
The LED Light module
bulb is normal.
Lighting companies engaged in LED replacement do not seem to figure this out.
However, it is not so simple to increase the light output to be equal to the brighter bulb.
These companies need to determine how to make brighter LED chips to manage the increased heat in a compact size, although still consumes less power than standard bulbs, and consumers cost less than arms and legs.
While their introduction may not make much sense to the average consumer, the company that introduced the lights saw the occasion as a royal premiere.
Lighting Science shows its lamp in a glass box with red fabric inside.
Osram siwania was dotted with lights on the floor of a cocktail party on Tuesday night.
Price is one area of the company\'s progress.
Last year, lighting manufacturers were talking about replacing LED bulbs, which would cost about $60 if any.
On Tuesday, several companies told me that they expect to charge between $20 and $30 once their fixtures go public.
Few people use 40-
There are watt bulbs at home, why not jump too low output, wait until 60-
Ready to sell lamps of Watt or higher equivalent?
Because these companies want to position themselves in the minds of consumers and become creators of advanced technology, even if few people actually buy their products in the first place.
Comments are no longer accepted.
Of course, people use 40-watt bulbs.
I use them in multiple
Floor lamp and small area lamp.
They are fine in the basement-lighting up a corner, for example.
A very bright light bulb can light up the entire basement, but the contents of the basement cast a dark shadow.
The two 40 watt bulbs in the double light bulb are perfect for reading. 50,000 hours?
You can add these in your will.
The advantage of this bulb is that the energy used by the bulb will be much less, and with the satisfaction of the market, the bulbs made, transported and market will eventually be much less.
We should move in that direction.
For the benefit of the Earth)on many now-short-lived products.
Eric didn\'t see the light. it was too bad.
LED lights are currently widely used in the automotive and truck transportation industries, using 1/10 of the power of incandescent lamps.
This means that truck drivers can use more than 10 times the lights on the truck without overloading the alternator.
You can always see this on every highway in North America.
It\'s time to change it to house lighting.
LED lighting has the ability to greatly reduce lighting power consumption.
In addition, the bulb will last 10,000 hours.
Of course, compared with the 100-watt refrigerator, air conditioning, deep freezing, etc. , the 1200-watt bulb is nothing.
I agree with Michael, 40.
The light bulb is great;
I want to know 25-watt?
I often want something dim and it seems like CFLs are hard to get down to that low.
You don\'t want everything to be lit up like a Hollywood scene.
Costco is selling an American LED Candra Barra replacement bulb, which is clearly stated in its packaging as equivalent to a 40-watt incandescent lamp.
I bought two packs of this loser (six bulbs)for my foyer.
In the mirror of that space, I can hardly see my face.
Since the Costco policy is still very generous, why don\'t I retreat directly? Simple.
My teenage child refused to turn off the lights anywhere in the house. At 1.
4 watts per bulb, before they go out to face their peers, let them dress themselves at dusk.
Anyway, their eyes are much better than mine.
Well, you may not know me, but I estimate that at least 60% of the bulbs in my house are 40 watts. Bring on LED.
I haven\'t sold the LED technology yet.
There are some disadvantages, including shortening the heat factor of the LED bulb assembly.
I think lighting companies will use their time to develop induction type bulbs that can be cheaper with current technology, and maybe they will find them when my CFLs run out!
I don\'t know how others like that their space is illuminated, but the day is bright and the night is dark.
If you need to light up a space, it is either a very closed space or at night.
All I can say is that having a dark basement during the day is the only time you want 100 watts.
Since there are fluorescent lights everywhere during the day that need to be lit, I don\'t think that only 40 watts will cause problems because I don\'t care to blind myself with lights at night.
Since they invented this, you have to change the light bulbs in every place to a 40 watt LED.
Like a poster said.
With the energy you save-
Only more than one bulb needs to be used. Poster 4;
Our children have similar problems.
We installed mechanical timer wall switch or switch with motion detector in closet and bathroom.
They worked very well and worked for about 20 years.
There is low level lighting in our house, also controlled by the timer (
Newer CFLs work with these)
I was burned due to poor quality of early CFLs and I would use LED lights to wait for the timing.
They sound great, but so did the early CFLs.
Only now can we find reliable CFLs with consistent colors and no flashing/buzzing sound.
All our camping gear uses led (
Flashlight, headlights and general lighting)
The battery seems to be forever.
It\'s not as simple as Watt.
Incandescent lamps and fluorescent bulbs emit light of 360 degrees. LEDs do not.
You need to see how the bulb is used and how you want to light something up.
If you sit down and read and turn on the light because it doesn\'t fall on the book, how much light is \"wasted?
Depending on the design the power of 40 watts can provide more LED Light module than 100 watts, if all the light points to where you want to see, or if you want to light up a room, less light can be provided. A few points.
When the rated working time of the LED is 50,000 hours, that is, when the emitted light drops to 80% of the original output, not when the LED goes out.
You can continue to use the LED for a longer time.
Dave , I don\'t think you know anything about the thermal properties of LEDs.
Actually, they are relatively cool, any hot problem with high heat
Power led can be treated with aluminum radiator and airflow.
The resistor element in the bulb has a greater thermal risk than the LEDs or fluorescent lamps.
I \'ve never heard of induction bulbs, so I can\'t say anything.
LED is very suitable for standard lights and street lamps (ie Sylvania).
We are a few years away from replacing 4\'fluorescents with LED.
The LED is also ideal for decorative lighting and high ceilings with difficulty in replacing bulbs.
Most of the good LED lights last 25,000 hours, and the mr16 lasts 15,000 hours.
The best advice about LED is to go to a reputable company.
People start LED companies every day, and LED companies fail every day. I love the 40 watt light bulb and it\'s all over my house.
They make fantastic lights and don\'t light up the place like a surgical suite.
They have a lot of bright reading! !
But no matter what the wattage is
What I care more about is the color.
I really appreciate the warm golden light from incandescent lamps.
Are these LEDs giving off the wonderful glow of an incandescent lamp, or are they giving off the harsh white glare that makes everything look white? ?
I don\'t need 40 w bulbs;
But I love the soft and warm glow of 15 bulbs-I use at least 8 bulbs in different parts of my home.
Hi, I have been using the new LED technology professionally since 3 years and in my opinion the fluorescent lamp is even efficient (Lumens/Watts).
So, for home lighting, replacing the fixture is a better option (
If you still have incandescent lamps)
It\'s a fluorescent lamp.
Fluorescent lamp consumption is low, longer than incandescent lamp duration.
I think our LED technology can replace fluorescent lamps in homes more efficiently and cheaply in the coming years.
At present, LED lights must be used in special applications where other lights have disadvantages.
If 40 W is not enough, why can\'t I buy another lamp with two bulbs?
I suspect I will use a lot, but I will buy some in the room where I often have lights on . . . . . . .
I\'m a little confused here.
The \"40 W\" LED bulb makes no sense, the LED uses a lot less power and will never use 40 W . . . . . . .
What do I mean by \"as strong as a 40 watt incandescent lamp\", but I think we \'ve had stronger LEDs for years?
The question is just the LED light that fits the normal accessory of the bulb?
40-there is a marketwatt bulbs.
The obsession of over-illuminated America will also pass, just like other fashions in history.
A very important consideration is how much light you get per watt.
You want to maximize your light and minimize your costs. (
You pay Watts. )This light (lumens)
Each Watt is a measure of efficiency.
Over 50,000 hours is the most important determinant of cost.
You can give me an LED for free, but I will lose a lot of money if it is 5% less efficient than a fluorescent bulb and over 50,000 hours.
The second consideration discussed in this paper is the efficiency range of the bulb.
In a relatively dim range, such as 60 lumens, the LED may be more effective . . . . . . But if most people want a bulb that produces 600 lumens, then that\'s the scope of efficiency that has to be judged.
I hope the New York Times will keep these factors in mind in every article about LED technology.
For example, in the long run, the difference in the purchase price of $50 or $20 is completely irrelevant ,(
About 50,000 hours).
Of course, some consumers will encounter difficulties in making long-term calculations . . . . . . But it would be helpful if the New York Times could make the calculations clear.
LED lights make sense for an ordinary home and can be \"free\" by installing solar panels and batteries.
Home with permanent free lighting! what a concept!
Now, add a refrigerator with super solar compressed gas
Like small hospitals in Africa, we reduced the cost of running the device, added a good microwave cooking system, a small garden, some compost, a \"dry\" Swedish style toilet and some other eco-toilets
Friendly features, mortgages can be paid, lifestyle is cheaper, and overall life in the US can slow down to accommodate our part --
Time, service industry employment market! Kick in super-insulation (
Industrial secrets, patent protection, etc)
For very low power heating and cooling, we can live in the 21 st century without even a telephone line to bind us!
Now, Obama, tax!
Things get messed up when the title announces the arrival of the 40 w led.
The 40 watt LED will be brighter than the street light and you don\'t want to see it in the desk or desk lamp.
I used three.
There are 5 watts of LED in the two desk lamps on my desktop.
These are great for highlight lighting.
Bright white light of these LEDs (under $10ea)
Because we are used to the soft glow of incandescent lamps in our home environment, it looks harsh.
My two lamps are metal goose necks and they don\'t even warm up from the bulb.
Math doesn\'t work for me.
A 40-watt incandescent lamp can produce 505 lumens or 12 lumens.
6 lumens per watt.
The latest Phillips Master LED lights of the Phillips 100,2700 K are 7 watts, producing 180 lumens or 25 lumens.
7 lumens per watt. CRI 85, 2700-3000K//www. lighting. philips.
Website/led _ lighting/product/main led/index. php?
Main = gbThis is far from 10 times the efficiency of incandescent lamps.
Davideo fficity is measured based on the energy consumption and longevity of the bulb, not that lumensI purchased one of the \"American lights\" embedded LED bulbs at my local Costco yesterday.
They don\'t work in the dimmer switch circuit, so we installed it in the bathroom.
It\'s not very bright, but it works well there-
This is mainly due to the blue shift in the light.
Our bathroom was done in a lot of dark earth tones, so in this case the blue light of this bulb is actually an emphasis.
This is not appropriate for most other lighting situations I can think.
As far as I know, only CREE makes bright \"soft white\" LEDs that are dimmable and I don\'t know how or where to get them.
Jay Broni: measure energy efficiency with lumens/watts.
If you\'re having trouble digesting this in real time, please peak in any version of the Energy Star SSL guide.
The master leadership that David refers to is not in line with the Energy Star guide in my memory.
