Dimmed to black that is
An LED light bulb which lasts for 25 years and costs just
88p a year to run has gone on sale in the UK. The Pharox switches on instantly and its makers claim
that it is the first low-energy bulb to give off the same light quality
and brightness as a conventional 60-watt traditional bulb.
The downside is that it costs €31 and is still as dim
as a rugby playing hillbilly whose family have been marrying their
sisters for 14 generations. But the manufactures claim that it can save €10 a
year off a typical household electricity bill.
The bulb is made up of frosted glass containing four
white LEDs and two red ones. A single LED has a lifetime of 100,000 hours around 50
years if used continuously. This is reduced by regular switching on and
off.
