Unreal Engine 5's 5.8 update includes a medium quality version of Lumen that is "twice as fast" as the high quality version, which is says is now the default for "handheld consoles".
According to their VP of Engineering:
“Lumen Light is designed to preserve much of the visual impact at a significantly lower GPU cost. That makes Lumen viable where it wasn’t before, including on Switch 2. And that work is already helping drive further nanite optimization efforts for the platform.”
