Me

I'm Santeri Lehtonen, an MA certified Finnish lighting designer specialising in live concerts, touring productions, and events. By leveraging modern pre-visualization software and advanced MA3 workflows, I handle the full chain of production so the core vision stays consistent from the studio to the stage.

I work closely with artists and teams to craft dynamic looks that serve the story on stage. Whether adapting a showfile for a tight club fit or scaling up for a festival stage, I focus on precision and impact. Currently touring as LD/OP with Antti Ketonen. Based in Helsinki, Finland, available for projects internationally.
