Minneapolis-St. Paul International Airport, one of the busiest airports in the world, is also known for its outstanding overall customer satisfaction, which can be attributed to continual renovations and expansions making air travel safer, more efficient and enjoyable. Most recently, in April 2003, the airport switched from the conventional halide lamp to a more energy-efficient pulse-start metal halide lamp which features an arc shaped tube giving a better color consistency, higher efficiency as well as a faster warm up period. Although the airport had a tight budget, and energy conservation was a chief determinant in selecting the new type of lamping, officials were unwilling to compromise light output. The benefits of the new lamps are yearly savings on energy costs, reduction of maintenance costs, and increased light output and color, which improves security by making cars more easily identified on security cameras. Not only did the relamping promise beneficial changes, but the local power company offered a large rebate for the retrofitting. A new type of ballast was required as the new energy source to power the lamps. The ballast features improved lumen maintenance, improved lamp color uniformity due to better lamp-to-lamp power regulation, and improved system efficiency.
