Low-energy bulbs 'cause migraine'
The lighting industry says that the latest bulbs do not flicker
Energy-saving light bulbs could trigger migraines, say campaigners.
The Migraine Action Association says members have told them how fluorescent bulbs have led to attacks.
The government is set to prevent the sale of conventional light bulbs within the next four years in a bid to cut carbon dioxide emissions.
Concerns have already been raised by epilepsy charities about an increased risk of seizures from energy-saving bulbs.
We would ask the government to avoid banning them completely, and still leave some opportunity for conventional bulbs to be purchased
Karen Manning
Migraine Action Association
Some bulbs use similar technology to fluorescent strip lights, and some users have complained that there can be a "flickering" effect.
They use approximately a quarter of the energy of conventional bulbs, and in September, Environment Secretary Hilary Benn said that a voluntary agreement with retailers would remove all conventional bulbs from the shops by December 2011.
However, Karen Manning, from the Migraine Action Association, said this could be damaging to some sufferers.
She said that up to six million people in the UK suffer from some sort of migraine attack.
"These bulbs do trigger migraines for some of our members - it's either the flickering, or the low intensity of the light, causing eye strain.
"We would ask the government to avoid banning them completely, and still leave some opportunity for conventional bulbs to be purchased."
Old technology
However, the Lighting Association, which represents bulb manufacturers, said that the latest energy-saving bulbs did not produce a flicker.
A spokesman said: "A small number of cases have been reported by people who suffer from reactions to certain types of linear fluorescent lamps.
"These were almost certainly triggered by old technology." Last year the charity Epilepsy Action reported that a small number of people with the illness could have seizures triggered by low-energy bulbs.

Low-energy bulbs 'worsen rashes'
Energy saving bulbs could reduce carbon dioxide emissions
The switch to energy-saving light bulbs may put thousands at risk of painful skin reactions, health charities warn.
Fluorescent bulbs can exacerbate skin rashes in people with photosensitive skin conditions, experts said.
The government is planning to prevent the sale of conventional bulbs by 2011 to cut carbon dioxide emissions.
Several groups including the British Association of Dermatologists called for exemptions to allow those affected to continue using traditional bulbs.
But representatives of the lighting industry said there would be alternatives to fluorescent lighting available.
Health conditions which can involve some form of light sensitivity, include the auto-immune disease lupus, the genetic disorder Xeroderma Pigmentosum (XP), certain forms of eczema and dermatitis, photosensitivity, and porphyria.
We certainly don't want to say no to greener bulbs just that other bulbs need to be available
Andrew Langford, Skin Care Campaign
It has been estimated about 100,000 people in the UK with these skin conditions will be affected.
Spectrum - an alliance of charities that support people with light sensitive conditions - says they have also been contacted with people suffering from ME who have had bad reactions to fluorescent light.
Other groups have warned that low-energy bulbs, which use approximately a quarter of the energy of conventional bulbs, cause migraines and increase the risk of seizures in people with epilepsy.
Phase-out
Conventional or "incandescent" bulbs are being phased out in a voluntary agreement with retailers and will no longer be on sale from December 2011.
Campaigners want people who have light sensitive conditions to be able to continue to buy conventional bulbs for their homes.
They warned that employers must also be able to purchase incandescent lighting as employees have a right to such adjustments under the terms of the Disability Discrimination Act.
Andrew Langford, chief executive officer of the Skin Care Campaign, one of the charities involved, said: "Incandescent light bulbs are the only source of electric light for many thousands of people with light sensitive conditions.
"Add to this the thousands of people whose conditions or treatments may secondarily cause them to be light sensitive, and you have a large number of people potentially being isolated in the dark.
"We certainly don't want to say no to greener bulbs just that other bulbs need to be available.
"It's hard for people to understand what it's like to live with one of these conditions."
He also called for a government-funded study into the effects of fluorescent lighting on photosensitive conditions as little research had been done to date.
"We have the anecdotal information - it's a shame people don't listen to those affected.
Dr Colin Holden, President of the British Association of Dermatologists, said: "It is important that patients with photosensitive skin eruptions are allowed to use lights that don't exacerbate their condition.
"It is essential that such patients are able to protect themselves from specific wavelengths of light emitted by fluorescent bulbs, especially as they are often trapped indoors because they can't venture out in natural sunlight."
Kevin Verdun, chief executive of the lighting association said only two-thirds of incandescent bulbs were being phased out. "These things have been taken into consideration and there will be bulbs they can still use. "There are also halogen bulbs and LED bulbs coming in in the next two or three years."

Low-energy bulbs 'could cause skin cancer'

Using environmentally-friendly light bulbs can be bad for your skin, say doctors.
Energy-saving light bulbs blamed for migraines The new energy-saving bulbs produce a more intense light and can exacerbate a range of existing skin problems.
New energy-saving bulbs produce more intense light
Now it is feared that thousands of people may be unable to use electric light in their own homes, visit family and friends, or have access to employment and public services if the government's plan to phase out the normal variety of incandescent lighting goes ahead without exemptions.
The warning has been issued by Spectrum, an alliance of charities working with people with light sensitive conditions, and the British Association of Dermatologists.
It comes after the Migraine Action Association warned the
energy-saving light bulbs could trigger migraines.
The government wants to phase out traditional, incandescent bulbs by 2011 but no allowances have been made for people suffering from light sensitive conditions who often suffer severe and painful reactions to fluorescent lighting and other forms of non-incandescent lighting.
Spectrum is running a campaign to raise awareness of the impact on people's health in response to the government decision to ban incandescent light bulbs. They claim as many as 340,000 people could be affected.
Andrew Langford, chief executive officer of the Skin Care Campaign, one of the charities involved, said: 'Incandescent light bulbs are the only source of electric light for many thousands of people with light sensitive conditions.

CLEANSING past an accidental breakage
is...so this says: so-easy!!! ¬v
Low energy light bulbs use less than 20% of the energy of a conventional light bulb, and can last up to 15 times longer.
Fitting Low Energy Light Bulbs is simple, helps the environment and should reduce your lighting bills.
So what type of low energy bulb should you buy?
Both CFL light bulbs (low energy light bulbs) and LED light bulbs offer substantial energy savings. LED bulbs offer the greater saving overall using less energy and lasting longer at 60,000 hours, however a greater initial investment is required. In addition alternative fittings may be required and at present they only provide directional lighting.
With improvements in LEDs making them more and more viable, they will be the choice of the future, but for now we would recommend choosing CFL bulbs. The energy savings are still very good and although they have a lesser life span at 150,000 hours, they are much cheaper and can directly replace your current bulbs which only last 10,000 hours, helping the environment and your pocket straight away.
Will just swapping light bulbs make a difference?
By swapping a normal bulb to an energy saving bulb you could cut energy wastage by three quarters and save £9 on your electricity bill. It might seem like a small change, but if every home in the UK changed just 3 light bulbs, enough energy would be saved to light the UKs street lamps.
But dont energy saving light bulbs use more energy when first turned on, therefore wasting more energy if switching lights on and off?
Carbon Footprint carried out an in-house investigation and found that if anything low energy bulbs used slightly less energy when first switched on, gradually building up to a continual wattage (which only took a couple of seconds).
CFL Low energy light bulbs contain mercury, is that safe?
Low energy bulbs do contain a small amount of mercury which is not at all dangerous when contained within the bulb. The bulbs should be disposed of responsibly and can be recycled either at your local councils Household Waste and Recycling Centre or at collection points provided by some light bulb retailers.
Should you break a bulb in the house, it is advised that the broken material is swept up using a damp cloth and both the debris and cloth put into a double layered plastic bag and taken to a collection point for disposal. The room should then be well ventilated for at least 15 minutes.

Health warning on low-energy bulbs
[FONT=Geneva,Arial,sans-serif]
Press Association [/FONT]
[FONT=Geneva,Arial,sans-serif]Saturday January 5, 2008 3:38 PM[/FONT] [FONT=Geneva,Arial,sans-serif]
The Government's planned switchover from traditional light-bulbs to low-energy lighting could cause health problems for tens of thousands of people with skin conditions including eczema, experts have warned.[/FONT]
[FONT=Geneva,Arial,sans-serif]And there were warnings that consumers will have to take more care disposing of broken or expired low-energy bulbs in order to avoid contamination with the poisonous mercury they contain.[/FONT]
[FONT=Geneva,Arial,sans-serif]The Environment Agency acknowledged that both retailers and the authorities need to do more to inform the public about safe recycling of the new-style bulbs as they become more common.[/FONT]
[FONT=Geneva,Arial,sans-serif]The process of phasing out the conventional pear-shaped "incandescent" bulbs and replacing them with more energy-efficient fluorescent models begins this month and is due to be completed by 2011 as part of the UK's efforts to reduce its greenhouse gas emissions.[/FONT]
[FONT=Geneva,Arial,sans-serif]But Professor John Hawk, dermatology spokesman for the British Skin Foundation, warned that the new-style bulbs will cause problems for people with light-sensitive skin, some of whom are already unable to spend time in buildings with fluorescent strip lighting, like factories and hospitals.[/FONT]
[FONT=Geneva,Arial,sans-serif]Prof Hawk told BBC Radio 4's Today programme: "Fluorescent lights seem to have some sort of ionising characteristic where they affect the air around them.[/FONT]
[FONT=Geneva,Arial,sans-serif]"This does affect a certain number of people, probably tens of thousands of people in Britain, who are flared up just by being close to them.[/FONT]
[FONT=Geneva,Arial,sans-serif]"Certain forms of eczema - some of which are very common - do flare up badly anywhere near fluorescent lights, so these people have to just be around incandescent lights."[/FONT]
[FONT=Geneva,Arial,sans-serif]A much smaller number of patients with very severe light sensitivity are unable to tolerate exposure to the small amount of ultra-violet light given off by the new-style bulbs, he added.[/FONT]
[FONT=Geneva,Arial,sans-serif]There are a "significant number" of people in the UK who are already unable to visit or work in buildings with fluorescent lighting, said Prof Hawk, adding: "It is people who will have to be exposed to them in their homes that we are worried for, and I very strongly suggest that incandescent bulbs remain available for use in the home."[/FONT]

The dark age of low-energy bulbs
Dullard politicians are telling us how to run our homes - in semi-darkness
Mick Hume
Late in the pantomime season Ken Livingstone, the Miserabilist of London, is staging a new version of Aladdin. At B&Q stores this weekend Londoners can get new bulbs for old by swapping incandescent lightbulbs for free low-energy ones (only two each, the genie of the lightbulb being less slightly generous than the one in the lamp).
So far, so what. But what turned me off was the mayor calling this eco-stunt a lightbulb amnesty. An amnesty is a period during which offenders are exempt from punishment, as when police turn a blind eye to those handing in illegal weapons. A lightbulb amnesty implies that the merciful authorities will let us carbon offenders dump our tungsten timebombs and avoid the electric chair.
The economic and energy arguments about different bulbs are as dull and cold as the light thrown out by the current low-energy efforts. (Perhaps those greens who claim these are bright and warm just eat more carrots than me.) But call it a lightbulb amnesty and you can reduce the issue to a simple moral message about the power of evil.
It seems that the use of energy and production of carbon has become the standard by which all human activity is judged. Low is seen as good, higher bad, regardless of how it might illuminate our existence. What next? An auto amnesty to exchange the car for a family rickshaw? Or an infant amnesty where we can swap our carbon-guzzling kids for free-range chicks?

Background
When an alternative scare story about mercury in low-energy bulbs arose (visions of the health and safety police swooping to change broken ones), Livingstone responded: We shouldn't be too alarmist. How true. Of course, it is not at all alarmist for the mayor to tell us we must switch to bulbs that save a halfpenny an hour in order to avoid catastrophic climate change.
So the genius of Thomas Edison is reinvented as a crime against the climate, while dullard politicians assume the power to tell us how to run our own homes. The lights are dimming, if not yet going off, over Europe. Welcome to the new dark age.
The Government's new non-educational brainwave for schools is to give parents daily online updates on their child's every move in the classroom. This surveillance system will be two-way: schools could also monitor how often parents checked their child's progress. The authorities won't learn that some of us don't want even more parental involvement. All we want is a properly funded local school staffed by good teachers that we can leave to get on with it.
On Saturday my wife and I saw Alan Bennett's brilliant The History Boys. The inspirational teacher holds his top class behind locked doors - not to interfere with the boys (he does that in public on his motorbike), but to avoid interference from anybody else. Today that would be deemed a worse offence than using a normal light bulb in a classroom.

Well done Mick Hume. As an ageing ecoish female I tried to do the 'right thing' last year and inserted low energy bulbs in the kitchen. Within days I had to replace the prime light source over the 'cutting areas' in order to prevent repeating my 2005 trick of spearing my hand with a kitchen knife destoning an avocado. The alternative is high powered reading specs and too close an affinity with food prep for comfort.
Our Ken obviously doesn't do the cooking.
Carol, Honiton, Devon
Perhaps miserabilist Ken could introduce an excess electricity 'Consumption Charge' for those that don't turn up to surrender their offending incandescent bulbs.
Fran Maguire, Stockport,
I wonder how long classroom surveillance will last when parents start using it to monitor the teachers' performance.

Are low-energy light bulbs really shining lights?
Wednesday, January 9, 2008
SAINT AND SINNER
So far, 2008 has been a bad year for the low-energy light bulb. It's been variously blamed for triggering migraines, causing skin rashes and emitting toxic substances once broken.
A motley crew of experts have launched a series of attacks on the fluorescent bulb, ranging from the Migraine Action Association and the British Association of Dermatologists to the Environment Agency.
A flickering associated with some bulbs is thought to cause migraines for a few sufferers, while fluorescent light makes rashes worse for people with photosensitive skin conditions such as lupus or certain forms of eczema.
Mercury in low-energy bulbs harmful in large quantities can be released when they are broken.
But shine some light on the complaints, and they seem to disappear somewhat. Mostly, they are responding to government plans to ban traditional light bulbs, not proposing we avoid low-energy bulbs altogether.
In September, Environment Secretary Hilary Benn said that a voluntary agreement with retailers would remove all conventional bulbs from the shops by December 2011. This month, shops in Britain begin the process of phasing out traditional tungsten bulbs.
Each of the organisations raising concerns about low-energy bulbs is simply requesting that not all incandescent bulbs are banned.
Yet only two-thirds of incandescent bulbs are being phased out, according to Kevin Verdun, chief executive of the Lighting Association.
Halogen and LED bulbs will still be available. In terms of disposal, the Environment Agency is urging that more information on safe recycling be printed on packaging.
It is not suggesting that low-energy bulbs should be avoided because of any dangers to health. According to Nottingham University toxicologist Dr David Ray, about 6-8mg of mercury is present in a typical low-energy bulb, which he describes as a 'pretty small amount'.
'The biggest danger is repeated exposure - a one off exposure is not as potentially dangerous,' he says.
While it's important to make information on potential hazards widely available, on balance, the low-energy light bulb is more saint than sinner. It uses approximately a quarter of the energy of conventional bulbs, saving at least 5m tonnes-worth of carbon dioxide emissions every year if used throughout Britain.
Together.com is running a month-long campaign on low-energy bulbs, including consumer offers. During January, there's a buy-one-get-one-free promotion in Tesco stores nationwide.
While stating that a public information campaign on disposal of low-energy bulbs was needed, Greenpeace's Louise Molloy also added: 'Rather than being worried about the mercury these light bulbs contain, the general public should be reassured that using them will actually reduce the amount of mercury overall in our atmosphere.'

LOW- ENERGY LIGHT BULBS 'CAN TRIGGER EPILEPSY'
Posted on Tuesday, June 26 @ 15:41:25 BST
Topic:
Energy saving light bulbs can trigger epilepsy-like symptoms in sufferers of the condition, it revealed yesterday.
The bulbs - soon to be compulsory in homes - have caused dizziness, lightheadedness and other symptoms experienced in the early stages of a seizure. Judging by the number of complaints to charities and MPs, thousands may have already been affected.
In March the Government joined other EU leaders in agreeing to phase out incandescent bulbs from 2009. The low-energy versions last longer and cut carbon dioxide emissions. However, Health Minister Ivan Lewis said there has been 'no assessment' of the impact on epilepsy sufferers.
In answer to a parliamentary question, he admitted that the bulbs may also affect the 16000 Britons with lupus, an autoimmune disease.
It is unclear how the low-energy bulbs are triggering the symptoms as, though they do flicker, the rate is different to that usually associated with seizures. The answer may lie in the way the light is generated with light produced by low-energy bulbs having a different wave-length pattern.
In recent months Geoffrey Cox, Tory MP for Torridge and West Devon, has received around 20 complaints. He said 'If I have had 15-20 letters, there must be hundreds around the country affected - even thousands.'
A spokesman for the charity Epilepsy Action said it was investigating after receiving several complaints.

Bright idea: Super-efficient light outshines low-energy bulbs
Last updated at 21:09pm on 28th December 2007
Comments (1)
Low-energy version of a bulb
A new generation of super-efficient light bulbs was unveiled by scientists yesterday.
They said the bulbs would spell the end of regular filament models within three years.
Employing Light Emitting Diode technology, the bulbs would use less electricity than the lowenergy versions that families are currently being urged to invest in.
LED lights, which are used in electrical gadgets such as mobile phones and computers, have been judged unsuitable to light homes until now because they are not bright enough to illuminate whole rooms.
But researchers believe they have found a way of making the devices much brighter without using any more power.
Faiz Rahman, who is leading the project at the University of Glasgow, said: "By making microscopic holes on the surface of the LEDs it is possible to extract more light, thus increasing the brightness of the lights without increasing the energy consumption.
"As yet, LEDs have not been introduced as the standard lighting in homes because the process of making the holes is very time-consuming and expensive.
"However, we believe we have found a way of imprinting the holes into billions of LEDs at a far greater speed but at a much lower cost."
The research team has been using a technique called nano-imprint lithography to etch microscopicholes on to the LEDs, allowing more of their light to escape.

The future: A close up of the new bulb
The project is being developed in conjunction with the Institute of Photonics and the University of Strathclyde in Glasgow.
"LEDs not only use less power than current energy efficient light bulbs but they are much smaller and can last years without needing to be replaced," added Dr Rahman.
"This means the days of the humble light bulb could soon be over." The researchers made use of nano technology --precision engineering of substances at molecular and atomic level. The techniques are increasingly being used in clothing, electronics and manufacturing as well as in health and cosmetics.

I have tried to balance the information [for, and against]
there is, so much more [of, a negative nature]
ie: 'anti-changeover'
