The greatest light output in a projected image is 4.66 million lumens, and was achieved by WestJet (Canada) in Hildale, Utah, USA, on 3 May 2017.

Canadian low-cost airline WestJet attempted the record as part of the launch of a new daily nonstop flight from Toronto, Canada to Las Vegas, Nevada, USA. Passengers flying overhead were able to watch the rotating circular projection to find out which seat won a trip back to Las Vegas.
