I’ve seen these in movies and videos before, you get a nice high brightness (moderately) low heat light like an HMI and stick it in a big white balloon. Fill with helium and strike the light. Bam! Instant moonlight. Not only is it good for making moonlight but it’s great for making soft lighting over a large area where a crane or the smaller China Balls arn’t practical. Plus they look real cool.
