The PFD light I use has no focusing lens, emits light over a hemisphere shaped area.
Play around and try different things. I've even used a Kleenex held on with an elastic band, puffed up, on a flashlight hanging from a cord going across top of tent, just makes a more diffused light.
But I tend not to leave a light on for a long time, so whatever works is fine by me.
