Globe and Mail photographer John Lehmann found Vancouver's 2011 Festival of Lights at VanDusen Botanical Garden gets more bang these days, using less power. This year there are 1.4-million lights spread over 12-13 acres. The 1.4-million lights are almost all LEDs. They use less power now than 10 years ago when the show consisted of only 25,000 incandescent lights. The invention of the LEDs is what allowed the show to grow to the size it is now. It takes a team of 30 volunteers (6 a day / 5 days a week) working Monday to Friday, every week from the end of September to opening day to unpack and check every string of lights to make sure they work.
