The lighting industry and the government have hit back at reports today that energy efficient bulbs provide an inferior light to traditional incandescent bulbs and can also pose health risks, arguing that such "scare stories" are completely unfounded.
According to a front page story from the Daily Mail today, shoppers are stockpiling their "beloved" 100-watt light bulbs after retailers stopped ordering new supplies of the bulbs under a voluntary agreement with the government.
It said that leading retailers, including Sainsbury's, Asda and Homebase, had already sold the last of their traditional 100W bulbs while others only had sufficient supplies to last only a few more days.
The EU is to impose a ban on sales of 100W bulbs from September as part of its energy efficiency drive, but the UK government brokered a deal with the supermarkets last year that will see the bulbs phased out from the start of this year, cutting annual carbon emissions by an estimated five million tonnes.
The Mail claimed that the move had prompted "panic buying" as shoppers seek to stock up on traditional bulbs that they claim offer superior light. It also argued that inefficient incandescent bulbs were cheaper to buy and easier to dispose of, while claiming that many energy efficient bulbs did not work with dimmer switches.
In addition, the paper cited concerns amongst unnamed experts that compact fluorescent bulbs pose a health risk and can trigger epileptic fits, rashes and migraines.
The report was slammed by both the lighting industry and the government, which claimed that CFLs represented a safe, high quality, cost-effective and environmentally friendly alternative to traditional bulbs.
A spokeswoman for Defra said concerns about the suitability of CFLs were entirely unfounded. "Nearly all energy efficient bulbs now are designed to work with bayonet and screw cap fittings and models are available that work with dimmer switches," she said. "Also last summer the Energy Saving Trust ran the Light Bulb Pepsi Challenge at shopping centres across the country and found that the vast majority of people could not tell the difference between the light provided by the different bulbs."
Industry body the Lighting Association also issued a statement arguing that health concerns related to CFLs have been overstated.
It said that while there had been a small number of cases of energy efficient bulbs being blamed for triggering fits, the older models that had been thought responsible had since been replaced by new bulbs that operate at a higher light frequency that do not have any known health impact.
It also argued that while energy efficient bulbs would already save users around £80 in reduced energy bills over the life of the bulb, up front costs were likely to come down still further as manufacturers begin to exploit greater economies of scale.
"CFLi lamps have evolved to the point where good quality lamps now are usually very similar in functionality to incandescent lamps," the Association said. "They last longer and they will continue to get smaller, better, more efficient, safer and less expensive."
Concerns over the Mercury contained in CFLs was also downplayed. The Lighting Association said that all CFL bulbs were in line with EU regulations governing the use of hazardous substances, adding that guidance was widely available to ensure consumers dispose of bulbs safely. Next generation halogen and LED bulbs that do not contain Mercury should also soon become widely available.

A bulb ban is wrong from EVERY perspective
Surprisingly, few question the overall thinking behind all the coming energy efficiency bans, light bulbs included.... Europeans choose to buy ordinary light bulbs around 9 times out of 10 (European Commission and lighting industry data 2007-8). Banning what people want gives the supposed savings - no point in banning an impopular product! If new LED lights -or improved CFLs- are good, people will buy them - no need to ban ordinary light bulbs (little point). If they are not good, people will not buy them - no need to ban ordinary light bulbs (no point). The arrival of the transistor didn't mean that more energy using radio valves had to be banned... they were bought less anyway. All lights have their advantages The ordinary simple light bulb has for many people a pleasing appearance, it responds quickly with bright broad spectrum light, is easy to use with dimmers and other equipment, can come in small sizes, and has safely been used for over 100 years. 100 W+ equivalent brightness is a particular issue - difficult and expensive with both fluorescents and LEDS - yet such incandescent bulbs are first in line for banning ! Energy? Since when does Europe need to save on electricity? There is no energy shortage, there are plenty of local energy sources, Middle East oil is not used for electricity generation. Consumers - not politicians - pay for the energy used. Certainly it is good to let people know how they can save energy and money - but why force them to do it? Emissions? OK: Does a light bulb give out any gases? Power stations might not either: In France and Sweden practically all electricity is emission-free, while a lot of it is in Austria, Finland and other states. Why should households there be denied the use of lighting they obviously want to use? Low emission households will increase everywhere, since emissions will be reduced anyway through the planned use of coal/gas processing technology or energy substitution. Also, the actual savings amounts can be questioned for many reasons: For a referenced list of reasons against light bulb bans, see http://www.ceolas.net/#li1x onwards Even if a reduction in use was needed, then taxation to reduce consumption would make more sense since government can use the income to reduce emissions (home insulation schemes, renewable projects etc) more than any remaining product use causes such problems. People can still buy what they want, unlike with bans. However taxation is in principle wrong too, at least on electrical appliances, for similar reasons to bans (for example, emission-free households are hit too).

CFLs are (mostly) good
I use CFLs everywhere apart from one ceiling fitting that uses spot lights on a dimmer. Nobody sells a mini R42 dimmable CFL yet and the dimmable CFLs I have seen are 20x as expensive as a 11W standard CFL. I use CFLs because I run my house lights from an off-grid solar installation and while I can have the whole house lit up like Blackpool for a measured 95W of consumed solar battery power, it would cost 455W in incandescent bulb power. It's not until you generate your own electricity that you realise how precious a thing it is. Installing nearly 5x the generating and storage capacity for the same functionality in my home would have been madness. CFLs should not be used in places where they are only started for a minute or two as they take a couple of minutes to warm up. They also degrade with use so that by the end of their life I've noticed that they get a bit dimmer than when new. LED will be the next big step forward. They use even less power, have no warm-up period and can be dimmed (either by turning individual LEDs off in the "small LED array" type or by high frequency switching in future "giant LED" types). They don't mind being on for hours or seconds at a time and promise even longer burn times than CFLs. In the room with the ceiling spot light I use a pair of 12V 2.5W LED wall lights because the solar battery is nearby but it's impractical to use 12V lights elsewhere in the house so I'm waiting for mains types to become available. Lots of light fittings are optically very inefficient though. The frosted dome glass bathroom and kitchen light fittings waste a lot of light and don't have reflectors inside. By lining the inside of the fitting behind the bulb holder with tin foil, I was able to reduce the wattage of the lamp from 20W to 14W with no loss of brightness in the rooms. Light fitting manufacturers should be made to be greener as well. Finally, don't forget the less obvious power hogs... My cooker hood now has two 5W candle CFLs instead of the two 25W incandescents it used to have.

Who should bear the cost?
Whilst agreeing with the principles, as a senior citizen I am already looking to reduce energy costs due to increasing prices. I am now being asked to pay exorbitant prices for replacement bulbs which will more than offset any savings I have been able to make without a guarantee of life or availability of a suitably sized replacement for all bulbs. I do not agree with the statement that smaller and lower cost replacements will be available eventually. These improvements are needed prior to the switchover. Surely industry or the Government (EC) who came up with this idea should be funding the necessary investment before forcing these changes on us.

Lies and dammed lies
Like a good little citizen I replaced all my light bulbs with the so called energy efficient ones. I even stocked up when I found them discounted. My findings have been disapointing. Firstly they do not last any longer (in my home at least)than regular bulbs but cost far more to make and buy. Secondly they contain electronic components the production of which does far more damage to the enviroment than conventional bulbs. Thirdly those electrical components cause massive amounts of electromagnetic interference from the long wave broadcast band through to the mircowaves and are ruining my hobby of amateur radio. I have to operate with all energy efficient bulbs turned off in the house. Finally as a suffer from migrains I can confirm that these bulbs do trigger them and I have removed mine in the main living area. Someone somewhere is making big bucks out of these not as green as they are painted bulbs.

CFLs inferior on most counts
When CFLs offer the same light output as their incandescent "equivalents", and provide close to full brilliance within seconds of turn-on, only then would I willingly convert to them. Meanwhile they come a poor second to traditional incandescents.
