With energy bills having rocketed in recent years, more households are using energy-saving light bulbs as a way to cut their electricity costs. As energy-saving bulbs have grown in popularity, so too has the range of bulbs on offer – making it that much harder to know which ones to go for when you're out in the shops.
"The sale of traditional incandescent light bulbs is being phased out as part of the Government's plans to reduce CO2 emissions, so we'll all have to switch to energy-saving versions in the next few years," says Martyn Hocking, the editor of the consumer magazine Which?. "The good news is that, as well as being better for the environment, energy-saving bulbs are better for your wallet. Although they may be more expensive to buy than traditional bulbs, they work out cheaper in the long run because they use less electricity and don't have to be replaced as often."
Although most people associate energy-saving bulbs with a poorer quality of light and slow start-up, standards in these areas have improved enormously over the past few years. Nevertheless, quality still varies from bulb to bulb, as do prices. While it's now possible to pick up energy-saving bulbs for as little as 50p, you can spend up to £9 on a single bulb. But, as ever, the best bulbs are not always the ones that cost the most.
When the consumer group Which? recently tested 16 different bulbs, it was Ikea's Sparsam stick (pictured), priced at £3.25 a bulb, which ranked top – scoring 75 out of 100. It was way ahead of the rest of the field, and was one of few bulbs to perform well in cold as well as in warmer temperatures. It lasts for an impressive 10,000 hours – but there is a slightly green hue to the light it emits.
Two of the 16 bulbs Which? tested cost a rather steep £9 – including the bottom-ranked Omicron Dimmable Multi-tube (pictured). Although this bulb starts up relatively quickly and, as the name suggests, is usable with a dimmer, it has a lifespan of just 8,000 hours and performed very poorly in colder temperatures. Overall, it scored only 59 per cent in the Which? tests.

Eco-Bulb Of The Future
LED lighting was discussed in the House of Commons, the UK’s legislative chamber, on March 5 as part of a debate on energy and climate change.
Joan Ruddock, Under-Secretary of State for Energy and Climate Change, was asked if there had been discussions between her department and the Department of Environment, Food and Rural Affairs (DEFRA) on the effect on electricity consumption and CO2 emissions of the installation and use of LED lighting.
Ruddock replied that “the Government certainly recognize the potential energy savings that ultra-efficient lighting technologies such as LEDs can offer. We continue to work to stimulate development and take-up, and officials in the two Departments have worked, and will continue to work, together on this issue.” Member of Parliament Philip Hollobone then asked, “LED lighting is super-efficient. It uses just 5 percent of the wattage of a conventional light bulb; it generates very little heat, which means that it reduces fire risk in applications; and it contains no mercury, which means that it is safer to dispose of. May I urge the Minister to have discussions with DEFRA on this issue? Can she also advise the House what the low-carbon business innovation unit within her Department is doing to promote this technology?
Ruddock said that the government agrees on the “huge potential benefits” of LED lighting. “That is why we have put some LED products on to our energy technology product list and why we have made those specific types of lighting available to benefit from the enhanced capital allowance scheme, which has delivered approximately £550 million in tax relief to those who have purchased products on the Carbon Trust’s energy technology list,” she said. “The potential for the makers and retailers of LEDs is considerable, and I shall pursue the points that [the questioner] has made. As I have indicated, I am sure that our officials will continue those important discussions.”
National Geographic
An article in National Geographic compared lighting technologies, and described the LED as looking like the “eco-bulb of the future.” However, said the article, the price is high and reviews are mixed.
“LED illumination can range from warm to what technology analyst Michael Kanellos calls ‘alien autopsy’…the bulb casts its light in only one direction, which is fine for recessed lights and for spotlighting a specific area but could be a drawback in lamps or globes,” said the article.
The author said that in a few years we should expect “a cheaper, more versatile LED” and that experts currently recommend compact fluorescents (CFLs) for most home uses…although the mercury content remains a problem.

Top five recycling, bidding and stuff for free websites
The top five recycling, bidding and stuff for free websites are:
www.freecycle.org
The Freecycle Network is a grassroots movement that started in the US and now runs in 85 countries worldwide. It enables local people to contact each other with stuff they want to give away for free, finding good homes for serviceable items that would otherwise clog up landfill sites. 'Ideal for decluttering,' says my friend Mandi.
www.gumtree.com
Gumtree started in March 2000 as a local London classified ads and community site. There are items for sale, for free (from pianos to tropical fish tanks) and to swap. One recent entry said, 'Large model ship to swap for whatever you have interesting.'
www.preloved.co.uk
Preloved - "the joy of secondhand" - was set up in 1998 by Ian and Louise Buzer from Woodbridge in Suffolk. It's free to sellers, but buyers pay an annual fee of £5 if they want to snap up bargains by seeing the ads as soon as they come online. You can narrow a search down to your local area. Bestsellers include antique furniture, prams and pushchairs, cars and wedding dresses - and you'll even find the odd horse.
www.ebay.co.uk
What did we do before eBay? As my friend Hannah says, 'We've bought all sorts of things - a fireplace, a violin, a tent, even a fairy castle.' All the excitement of an auction at bargain prices.
www.schoolstrader.com
A website that enables independent school parents to advertise items for sale - from holiday homes to musical instruments. Free to users. There are sister sites for primary schools, secondary schools and universities.

Britain returns to thrifty domesticity
A revival of 1950s style domesticity has swept Britain due to the economic downturn. Consumers are applying a do-it-yourself attitude to all areas of daily life by making clothes, growing vegetables and dying their own hair.Sales of knitting and dressmaking equipment are powering ahead - knitting needles are up by 7 per cent and sewing machines by 34 per cent according to the department store chain John Lewis.
Meanwhile garden centres are reporting strong demand for fruit bushes - up 68 per cent last year - and hardware stores have brought out budget gardening tool ranges. Although the motivation for the return to the thrifty, homely appears to be money, the new habits may stay once the economic good times return, at least according to one expert.
"When the economy starts to recover people will have adopted old domestic skills which they will continue to use. The focus will be on sustainability; people will be more self sufficient," predicted Reshema White, of St Andrews University. One of the easiest ways for people to save money is to colour their hair at home rather than at the hairdresser.
Sales of hair-dying kits are up 17 per cent rise at Superdrug, while Sainsbury's is selling a third more hair dyes. "For the cost of one salon hair treatment you can colour your hair at home for an entire year - and still have change for hairspray," said Daniel Hadley, Superdrug's hair dye buyer.
A new generation of twenty and thirty- somethings are taking up hearth-side social activities such as knitting instead of going out. Knitting clubs are opening across the country, attracting young professionals who are keen to save cash. I Knit London have begun to run three times as many knitting classes for beginners as last year due to a sharp rise in demand.
