Why is this better than an ordinary lantern? |
|
|
A little incoherent, but I think what he's saying is that instead of a plain lantern that has just plain glass on the sides, it's got a lens on each side. 'Caved in' indicates a concave lens, which focuses the light instead of scattering it, so you'd end up with a bunch of small points instead of a field of light...I don't really know what he's trying to do here... |

Concave lenses scatter light. Convex lenses focus it. I'm not sure how much more "scattered" light can get than the way it initially comes from a light bulb (i.e. radiating in all directions), though. |
