“Many congratulations my love” by a heart and birthday cake with candles emoticons. The Burj Khalifa light and laser show, on the edge of the Burj Lake, is a massive draw in the luxury Middle East sunshine destination. The iconic tower becomes the biggest display screen in the world at night thanks to nearly 18 miles of cables, 1.1 million pixels and 118 tons of light beams and accessories. Recent reports put the cost of placing a three-minute promotional ad or message on the tower’s facade at a minimum of £50,000, with the price rising at weekends.
