The Surf de Nuit is a unique competition gathering thousands of spectators each year in August on the Sables d’Or beach in Anglet, France and sees twelve of the best professional surfers duke it out by night under the light of gigantic Airstar balloons. Equipped with LED-lined surfboards (lumiboard), the riders compete for this coveted League trophy and put on a real show with daring tricks.
Both the logistics and power supply are handled by the technical team from the city. One of the Anglet city partners is none other than Airstar, whose South West branch has been working on this exciting project for the last 10 years.
Florent Gatard, Airstar Business Director, explains how it was able to perfectly light up the surfers and their surroundings, dozens of metres away from the shore. “Because it’s a one night only event, we virtually have no margin for error. We need to calculate the best position for our Solarc lighting balloons according to the tidal range. The Solarc balloons are the most powerful in our range and they play a critical role in the success of the Surf de Nuit. Because the water doesn’t reflect light, maximum lumen output is required as close as possible to the surf zone.”
Floating above the open ocean and delivering 18kW (12kW HMI + 6kW halogen), a colossal five-metre wide helium inflated Solarc lit up the surfing area and allowed the surfers to see the waves coming. First, an anchorage point was made with a buoy connected ballast before being carried on foot and then by swimming when the tide is at its lowest. Once the tide was back up, two Airstar technicians were taken on a jet ski by the Anglet lifeguards to put the huge lighting balloon in place.
Two further Solarc 16K of similar dimensions and hosting HMI lightbulbs delivered the required light output on the shore. As the event unfolded, they were regularly pushed further away into the ocean, up to 50m and following the ebb tide, so that the riders were perfectly lit for the whole duration of the competition, which ran from 8pm until midnight. Magnetic IREM 4K HMI ballasts were installed at the end of the sea wall, powering and swerving the Solarcs with a special 125m long extension cord. The HMI bulbs integrated within the Solarc balloons were able to light up the whole area with a powerful yet non-glare white light.
On the beach, the rocks and the spectator lighting were managed by four 1,200W Crystal 160 lighting balloons mounted on a pole and showing the Anglet city logo. All the balloons were installed in half a day while the beach remained opened to the public—and the dismantling took a mere two hours.
Guillaume Cazet, Event Department Manager at the Anglet city council, confirms that it would be very hard to run the event without the use of the Airstar lighting solutions. “The lighting from Airstar is really innovative; it didn’t disturb the surfers and allowed the crowd to follow the competition thanks to a superb light.” Cazet sees a lot of potential for the brands to have their name associated with such an international event, as the lighting balloons can be branded with a sponsor logo.
“The Airstar lighting balloons are not only efficient, but seeing them floating above the ocean automatically attracts a crowd, who come in thousands at dusk. We really couldn’t do without them,” concluded Cazet.
