eco-lightbulbs changed my life and my bills
I never worry about starting.
Increase the time, lumens per watt and color spectrum, or ask if I can find the right bulb for the most embarrassing outlet in my home.
The most exciting bulb
The related thing that happened to me was a late introduction in the middle of me.
20 s, to the embedded halogen lamp.
Now it\'s almost obsessed.
No matter where I go, every room I enter, I am counting the wattage of the lights.
Last week, I noticed from the dentist\'s chair that there were at least a dozen 50-
Watt halogen embedded in the ceiling and a small amount of fluorescent stripes (
Except that super-
Bright lights on my face).
From my desk I can count 160 stripes and 50 separate bulbs --some energy—
Efficient, many no, open when the sun is shining outside.
In a small clothing store in Bristol, West England, I counted 50 hot ones and 35
The Watt spotlight points to walls or clothes.
In the first half of the store.
All the electricity was wasted as heat.
All this extra carbon emissions. . .
These days, I am very upset by my mental math.
Of course, I\'m not the only one wearing a bee hat.
Newspapers and comment blogs have flooded this year. mostly angry)
About the parallel demise of our gradual shift to green lighting, especially traditional incandescent lamps --
It is now gradually banned across Europe, which is a big stimulus to the euro.
Lamenting the death of an incandescent lamp is as stupid as complaining about the car becoming more fuel
Effective, or decide that you want a course of le honeycomb instead of a breath-taking pain to treat a headache.
Even if you\'re not interested in climate and energy
The argument for saving money is that it makes sense to throw away incandescent lamps purely based on the money you save on your electricity bill.
My own transformation started with an innocent question about my life, as I finally started working on auditing my home\'s carbon footprint earlier this year.
As part of a larger plan for green my home, I have asked Russell Smith, Eco Parity of sustainable construction companies, to conduct an energy survey of my frozen energy
Hungry Victorian terrace home.
He thinks lighting is a major problem.
The cost of powering a large number of bulbs hanging on my ceiling and screwing in or poking into a desk lamp increases my energy use and therefore my carbon footprint.
These incandescent lamps are the same as most of the lights in most British homes.
In fact, most people in the world can still get artificial lighting from these glowing tungsten wires stored in glass
Closed vacuum, the design that has been around for more than a century, has barely changed. In our climate—
Sensing time, they represent an energy burden that cannot be defended: up to 95% of the electricity consumed by each bulb is wasted with heat.
Overall, lighting accounts for 28% of my energy use and more than half of my electricity bill.
I\'m producing about 1.
As long as my lights, there are 5 tons of carbon dioxide per year.
This must change.
I always knew that I would trade incandescent lamps for more energy.
Efficient compact fluorescent lamp (CFLs)
It\'s one of the easiest ways to reduce my carbon footprint, but I \'ve never really quantified what that means to me.
CFLs is a miniature, more complex fluorescent stripe, about 10 times longer than incandescent lamps, with a 80% reduction in energy consumption.
I spent the next few months (
Maybe too much)
Find and test different energy at night, weekend and lunch time
Saving bulbs, each bulb represents more cutting
More advanced lighting technology than last time.
I am very familiar with terms like GU10, R50, E14 and E27 (
Technical labels for bulbs and sockets of different shapes
Look, I\'m doing this so you don\'t have. .
I also see the future in Superbright light—
They were familiar with the car dashboard and bike lights and they broke all the energy saving records.
In a few years they will also be all over your home, without the shame of CFLs.
When I came out of this long journey through the bright side, my amazing 1. 5—
The habit of carbon dioxide per ton has fallen to less than 150 kg per year.
Think about what happens if everyone does this.
According to the British Energy Conservation Trust (EST)
In an ordinary family, electric lights account for about 20% of electricity bills.
British people spend near gbp2.
Every year 3bn is powered up to run their family lights, if everyone changes their old lights
Energy style lights
Saving alternatives, the electricity saved in one year will make the country\'s street lights run for four and a half years, or provide nine months of electricity to each house in London.
If only one 100 per head of household
Watt incandescent lamps with energy
Saving energy, saving carbon is equivalent to 200,000 cars a year.
The government also realized it was a quick victory.
Earlier this month, 27 countries in the European Union banned incandescent lamps rated at more than 80 watts.
Next year, more than 65 watts of bulbs will be banned until the incandescent lamps disappear completely in the next decade.
From the United States, Australia to Brazil, Turkey and Malaysia, the world has also announced bans.
However, not everyone is happy.
According to their critics, CFLs will send out a cold light that will take a long time to warm up and may even make you sick.
\"Almost all of our work seems to be trying to break these myths,\" said James Ross, an Lighting expert at eastern time.
\"There are a lot of wrong views on energy --
Save light bulbs.
In the early days, with the development of technology, warm-
General light output and their size.
These are still at the forefront of many people\'s minds.
But these problems are solved by modern technology.
\"It\'s not like the incandescent lamp is not working well.
Invented by Joseph Swan or Thomas Edison at the end of the 19 th century (
Depending on which side of the Atlantic you live on)
The first design produces light by electricity through the carbon filament of bamboo;
When it gets hot, it emits orange light.
The longer the filament, the more light is emitted, so in order to ensure that the bulb is kept in a practical size, later versions use long bamboo strips curled into tight coils.
By the beginning of the 20 th century, tungsten had replaced bamboo because it was the longest-surviving material at the hottest temperatures.
The curly filament curled on itself to form a brighter filament --the so—
Placed in a vacuum or inert gas to extend the life of the filament.
To a large extent, that\'s why incandescent lamps have been around for more than a century.
At the same time, fluorescent lamps first appeared more than 80 years ago.
Transmit electricity through mercury gas, they produce a large amount of ultraviolet rays, which are absorbed by phosphorus chemicals inside the glass tube
Then put this fluorescent body.
Emit energy in the form of visible light.
Fluorescent tubes are more expensive to make than incandescent lamps, but the process it uses to make light is at least five times more efficient than incandescent lamps. (
The efficiency of the lamp is measured by the amount of light generated per watt of power, measured by lumens: Incandescent lamps produce about 10 lumens per watt, and halogen lamps increase this ratio to about 20, the output of modern fluorescent lamps is 50-60. )
In their 50 s and 60 s, fluorescent lamps flooded offices and factories, while inefficient incandescent lamps are still popular at home, thanks largely to their warm yellow light.
If it weren\'t for the development of fluorescent chemicals in fluorescent lamps in their 70 s, that would have been the case.
\"Instead of producing a fluorescent substance that produces white light, we use three kinds-
Green, red and blue
Mike Simpson, technical and design director at Philips Lighting, explained: \"mix them to get white . \".
\"One of these spins --
These products are not sensitive to heat, so you can make them hotter, but they also provide better color quality.
This also means that manufacturers can change the color of the light emitted by fluorescent tubes and make them thinner.
By 1980, the first compact fluorescent lamp was made by bending the thin tubes twice and placing them in a glass container, just like a jam jar attached to the base of the bayonet socket.
\"At that time, you will take out 100
Watt incandescent lamp, put in 20-
\"Watt fluorescent,\" Simpson said.
\"Everything that has happened in the last 20 years is to make it smaller and more efficient.
\"At home, I have an incandescent lamp mixture rated from 20 W to 100 W.
There are seven reflective bulbs in the kitchen alone, each 50 watts, and four 40 watts in the upstairs bathroom.
In total, I have at least 1,500 watts of lighting around the house.
Replacing the main light for each room is simple: Now, there is a range of cheap, reliable CFLs.
The color of the lights is not even a problem (
If it\'s important, you can often choose how yellow you want the light to be)and the start—
My new light bulb is coming sooninstantaneous.
The problem is more of a lighter in my kitchen and bathroom.
There seems to be less low
Energy choices, finding the right spotlight requires a lot of diggingshaped bulbs.
I finally found some by low-
Energy lighting company Megaman on professional lighting website (
Although I have seen the same bulbs in DIY stores since then, the mainstream stores and supermarkets have become more and more light bulbs).
The impact of the new lights on my carbon footprint and wallet is clear: from the 1,500 watt lights in the house, I now have about 150 watt lights doing the same work.
By removing the lighting power supply of 90%, my monthly electricity bill was reduced by about 60%.
So is this the end of my lighting story? Not quite.
CFL technology 20 years ago, another lighting technology is accelerating to further reduce our energy consumption.
Since the age of 60, LEDs have been present, generating light by powering up between thin layers of different semi-LEDs
So far they are only used as indicator lights on phones, car dashboards, and dotMatrix display.
They were expensive and used to offer only certain colors (
Usually red or orange)
And not bright enough to illuminate the whole room. In the mid—
However, Japanese scientists in their 90 s invented the first blue LEDs.
By applying these LEDs to fluorescent agents, the LED can eventually produce white light, prompting large electronics companies to accelerate the development of LED bulbs.
Philips recently produced a 3-
Watt bulb with same light output as 35-1
Watt halogen light bulb-
Very expensive (GBP25)
But Philips says it will last 15 years.
Given the amount of power the bulb will save, in general, it can have a good impact on your pocket and the planet.
If all domestic lighting in the UK is switched to led, then the power burden on lighting is probably 10% today.
Like all technologies, the led will undoubtedly get better and cheaper.
Hopefully, in a few decades, all the lighting in a house will use the energy equivalent to an incandescent lamp today. Is this too much, is the carbon footprint of our home lighting almost zero?
At least that way, I won\'t turn my nose at the owner.
