Light Spells and Vision Penalties -- Spells and Exploits Contradiction

This strongly suggests Exploits is just wrong and should be ignored, because that doesn't make any sense at all; it means casting Glow at different energies has no effect (alternately, just errata the cost of Glow so it only has a single cost).

However, the problem might be the interaction between Exploits and Spells. The original DF was specific about candles and torches eliminating darkness penalties out to a radius, and then -3 to 3x that radius, and that presumably was a simplification.
