GR translation: till it clog the lantern-light of the meeting hall

[Mike Jing]

V743.5-14, P757.32-758.1   They are expected to pass a resolution tonight
asking Great Britain for Commonwealth status, and perhaps even to apply for
membership in the UNO. Children in the parish schools are being asked to
pray for their success. Can 13 years of Vatican collaboration have
clarified the difference between what’s holy and what is not? Another State
is forming in the night, not without theatre and festivity. So tonight’s
prevalence of Maitrinke, which Džabajev has managed to score several liters
of. Let the village idiots celebrate. Let their holiness ripple into
interference-patterns till it clog the lantern-light of the meeting hall.

Which of the following senses of "lantern-light" is being used here:

a. The light from a lantern;
b. a ‘light’ (i.e. a glazed frame or sash) in the side of a lantern
(lantern n. 4);
c. an arrangement for giving light through the roof of an apartment.

lantern
n. 4. Architecture. A structure, either square, circular, elliptical, or
polygonal, on the top either of a dome or of an apartment, having the sides
pierced, and the apertures glazed, to admit light; a similar structure
serving as a means of ventilation, or for any other purpose.
