I've run a bunch of low light matches/stages. Usually we would provide some ambient light but often not enough to be able to rely totally on night sights. Other times I force them to use a flashlight (no weapons mounted lights) either their own or a provided light. It's interesting seeing how people deal with it and let them find out what works for them and what doesn't. Most people don't get the opportunity to shoot lowlight with live ammo so IDPA club matches are a good place for them to get some experience.
If you're setting up a low light stage for a sanctioned match you have to make it so it's the same for all competitors. To the extent where they have to use a provided light (same for all).
