How to light megastructures in Minecraft without torch orglowstone spam?

I am building a very large underground airbase/bunker, and am having lighting troubles. Torches would look wildly out of place in a modern build, and even using glowstone doesn’t seem to be having much of an effect, as the light diminishes a set distance from the block. Well, my hanger is 30 blocks tall. The roof is plenty lit, but the floor is not.

This is with a Night Vision potion active.

This is without.

I’m running Worldedit (only way I can build something this big without taking a year) on 1.14.4, so any mods that work with that would be fine.
I have used Little Tiles and Chisels and Bits on another world in 1.12.2 to fill walls with glowstone for lighting, but I keep getting a glitch on there that makes random sections of the tiles disappear until I place a block next to them. If someone has a solution for that, I would use Little Tiles. Does Little Tiles for 1.14.4 have the same glitch, by the way?
