  I think this is the same 4 for £1 offer on bulbs which has been posted before.
  
  I got 8 and, yes, the short stumpy ones are much better for lamps - the long ones stick out through the lampshade. Only had 40watt-equivalent ones when I went.

  You will find that ordinairy dimmers do not work with the modern high efficiency bulbs. The bulbs work on a similar basis to fluorescent tubes where the powder coating inside the tube / bulb glows when a current is passed. They will only operate on a fixed current which is reduced by ordinairy dimmer technology and therefore the tube / bulb will not function. No light.
  
  Ordinairy traditional 'filament' bulbs rely on the electricity heating up this thin filament wire until it 'glows' bright. Dimmers merely reduce the power going through this filament and therefore the wire does not glow so brightly. Filament is changing from ' white hot' to 'dull red ' with change in power. Unfortunately the technology for similar control on new type bulbs does not appear to be in the public domain 'yet ' .
  
  My personal issue with the new technology is the speed of the bulbs reaching full brightness. I have some recently purchased cheapo Phillips bulbs which take ages. Probably ok for constantly lit areas but certainly not for the bathroom where it is quite important to get to a ' facility ' quickly !!

  Megaman make a range of dimmable flourescents, which work off a normal on/off light switch; you toggle the switch off and on again quickly to change the light level.
  
  Here's an example - http://www.litebulbs.co.uk/product.aspx?Product=21989
  
  Unfortunately, they are a lot more expensive - most places that sell them works out to about 10 quid each.
  
  There's another one made by Philips which just has two levels, "normal" and "nightlight", which you can get for about £6.50 - http://www.iguanadirect.co.uk/iguana/viewProduct.do?product=8104&productAreaCode=20 - which is handy for a kids bedroom, and probably cheaper than buying a dimmer switch to replace a normal switch. Having said that, over-use of nightlights is suspected to be bad for children's eyes development, so cost isn't the only issue...

  thanks, its a shame about the dimmer thing, it just means that i can't replace all the bulbs in the house until they sort out the dimming properly.

  Yep ive noticed Phillips bulbs take a while to reach full brightness. The 100W equivalent bulbs seem to be ok though. I notice it more on lower wattage bulbs hence I only buy 100W equivalent bulbs now.

  My missus had been suffering from migraines for the past 6 months. Never had them in the past. The doctor couldn't explain it so i was looking at possible causes on the intenet and found some other people with similar problems who had linked it to energy saving light bulbs. Then it clicked, i had been using them from around the same time as the migrains started. I changed the bulbs back to standard ones and she's had no problems since.
  
  There have been some worrying study's done by top scientists who think these bulbs are bad for your health, not just for the very poisonous mercury in them if broken but for the type of light they give off.
  I own a buiseness where we have fluorescent tubes and we've always had to have diffusers over them for health and safety, yet energy saving bulbs are completely exposed.
  
  The government are making these bulbs cheap or giving them away at the moment to encourage people to use them so they can get rid of classic bulbs by 2010.
  This is all to meet the carbon emissions totals put on us by the EU who do not have our health at the top of there list of priorities.
