as an aside, with a headlamp or flashlight, one can make an effective light diffuser using some opaque white packing foam type stuff and an elastic to hold it in place. Make a sort of dome shape over the light source and or including a piece of white paper as a reflector and while not perfect, its fairly easy to get a nice diffused light source for inside a tent or at a picnic table.

The bigger the "dome" or thereabouts shape, means a larger diffuse lighting source.

both foam packing and paper and elastic don't really weigh anything, so worth playing around with trying it out at home.
I used to work doing photography lighting, so specifically thinking all the time about how to modify light, and this is a pretty effective way to diffuse a directional harsh beam.
