This is a very old story. A more recent one (January 2015)Â suggests that scientists have found a way to make the old-style bulb more energy efficient (better than LEDs). I should point out – since the Daily Mail skims over it – that it is only “proof of concept”. Such bulbs are not being manufactured yet, and I would suggest that they are years away – and they may not even make it to market. For one thing, they will still “burn out”, whereas LED bulbs don’t.
Not to be outdone by those Luddites at The Daily Mail , The Sun is giving away energy-efficient light bulbs. This particular story is from 3 January, but in today’s paper copy they’re advertising that tomorrow they’re giving a free one away in partnership with Asda .
Incidentally, I’m getting a lot of hits by people searcing for ‘ Pharox 240v light bulb ‘ or similar. The Pharox appears to be quite difficult to get hold of but you can easily buy equivalent models – take a look here and here.
