The solution is a number of 10 meter high steel pylons with a continual aluminum truss that will run the entire 5km distance of the circuit. Mounted on the truss are all power, communications and fiber optic cables.
There are also 1,600 special lighting projectors manufactured by Valerio Maioli S.p.a. of Ravenna, Italy using metal halide lamps spaced every 4 meters. These projectors are removable for quick replacement and will have a focusable reflector so that each section of track can be precisely lit.
Interestingly, SingaporeGP have opted for a lamp that is lower in colour temperature (4,200 Kelvin degrees) than used in stadiums (which use a brighter, whiter light of 5,500 Kelvin degrees). The logic behind such a move is sensible as the lower temperature will allow people and television to observe a more natural setting – especially since the route is lined with beautifully maintained trees. However the disadvantage is that Singapore is a tropical climate and – especially during inclement weather – the lower temperature lights may not work as well.
Notwithstanding, one of the excellent aspects of this lighting option is that the entire track will be evenly lit! Gone are the days of missing the action as a camera quickly pans from bright daylight to a shadowy part of the track.
But best of all is that the photography and video will be superb! Watch out for this race being broadcast in high definition – we tip this race to have some of the best images from the entire 2008 race schedule!
