A high-candlepower utility light should be more than sufficient, and they make them in a portable handheld configuration. Wide cone of light so it works shotgun-style: hard to miss.
That has a further advantage: long distance dispersion. The last thing you want is people point skywards with powerful lasers - there's other stuff flying there that could be harmed. Even if a bright light doesn't affect the thing directly, it'll be much harder filming when it has to look into some high candela sources.
It also makes it easier to hit with buckshot :)
