Answer to 2.
The lumen output of lanterns and other light sources can be measured in an integrating sphere:

It’s a large, hollow sphere with a reflective white inner wall. The light source is place in the center. All the light it gives off is reflected by the walls until it reaches the detector.
You can do a Google search on “integrating sphere” if you want more details.
