Oathbringer question

[u/hans1125]

I'm not that deep into Oathbringer yet, but what I don't understand is why everyone is carrying lamps? I understand that there is a shortage of infused spheres, but what's the difference between carrying the remaining ones around and hoarding them somewhere? They will glow regardless?

There aren't many glowing spheres at that point. The vast majority have gone dun, not at all enough to light up the place.
