Philips today announced that its lighting projectors have been selected by Valerio Maioli S.p.A., the Italian consultant company appointed by Singapore GP Pte Ltd., to light up the first ever Formula One night race on September 28th in Singapore.
The Philips projectors were selected because its lighting achieves near-daylight conditions at night, providing a safe environment for drivers on the race track, even at speeds of more than 300km/h (~186mph).
The Philips Lighting projectors are designed to provide also an experience for race attendees and television viewers at home by meeting High Definition Television (HDTV) broadcast standards.

The Marina Bay Street Circuit in Singapore is fitted with nearly 1,500 lighting projectors, illuminating the 5.067km track with light that is four times brighter than a football stadium at night. Because the track is a street circuit, the lighting system is temporary. The heights of the lights will vary to accommodate the trees lining the road. The lights are also set deliberately lower than the canopy, and will not interfere with underground public services such as water and gas pipes, and electricity cables.

A Formula One race at night will be definitely exciting to watch. I guess it would be disaster for the drivers if the power fails during the race.
