The IMAX theatre in Waterloo underwent an LED retrofit project to upgrade its lighting system. Over 33,500 fluorescent tubes were replaced with more energy efficient LEDs, reducing annual energy consumption by over 46,000 kWh and CO2 emissions by 97 tonnes. Advanced control software was also installed, allowing dynamic lighting effects through 480 individually controllable fixtures across 120 zones, enhancing advertisements with animations and transitions. The upgrades improved image quality, reduced maintenance costs, and allowed remote operation and integration with social media.
