place torches in a planar huge room?  If I have a nice field
cleared to muck about in, what's the best way to light it up so
no hostile mobs can spawn? What if I use torches? What if I use
Glowstone so it's all still flat?  share|improve this question

luminescence of 15, whereas torches only provide 14. However,
placing the glowstone block in the ground reduces the area that
it lights up to that of a torch, whereas placing a torch on the
ground lets it provide maximum light while still remaining flat
to walk on, just not to look at.  It all comes down to choice
really. Do you mind looking at torches sticking out of the
ground, or are you willing to use as much glowstone as you need
to keep it lit?  Light loses one level per block traveled from
it's source. Mobs spawn
