I've got these bulbs downstairs and they are FANTASTIC!! When you get up on a dark morning feeling rubbish and switch one of these on you'll feel a whole lot more alert as soon as the light hits your eyes. They give a clarity of vision because you see all the colours and contrasts as they're meant to be (hence the term "Full Spectrum) instead of with the yellow tinge given off by normal bulbs. This makes for less eyestrain when reading newspapers or using computers. Crucially they have prevented my longterm SAD and keep my natural rhythmns as they should be. Evolution has made our bodies (and specifically our hormones) governed by daylight so it makes sense. They should be compulsory in offices to help people work in the winter!! A simple way to feel better all year round.

Q: I would like to purchase some of these low energy light bulbs but just need top know the dimensions of the bulbs before i purchase as some are too long for my lamp fitting encasement. however these look similar in size to a traditional lightbulb. appreciate any help you can give. Thanks Karen

A: You would be correct in your assumption that they are approximately the same size as a traditional bulb, and should therefore fit most lamp fittings. Hope this helps. Thomas.
