At 21:15, a two-and-a-half-minute opening sequence will culminate with a
beam of light shooting up the tower and radiating out over London.
The tower will remain illuminated until 23:00 and light up again the
following night at the same time.
200,000 watts – 7.5 billion candlepower – of energy-efficient lighting,
the same wattage used to light the Eiffel Tower in Paris, will
illuminate the 219 metre tall structure.
Visible across London, the explosion of light will culminate with a beam
of light shooting up the tower and all over London, representing the
invisible digital TV signals.
More than 6 tonnes of lighting equipment has been installed on the tower
in readiness for switchover. The 7000 watt, billion candlepower search
lights that will beam out across London weigh 100 kilos alone have been
installed 130 metres above the ground by a team of 20 riggers
In addition to the public lighting display, there is a special event at
the foot of the tower to mark the switchover. Hosted by Chris Evans, the
event will feature an appearance by Sir David Attenborough, who is
celebrating his 60th year in broadcasting and will talk about the
evolution of broadcasting during his lifetime.
