The spell "dispel magical protection" is designed to do what the spell name
says, remove magical protection effects from the target. True, there might be
one or two exceptions, but what it mostly does is remove prots. Light spells
are not prots, neither in RPG terms nor in code. Having dmp remove them
doesn't make a lot of sense, nor would it be easy to code. If you want to
remove your own light spell, use darkness. If you want to remove someone
else's light spell, you might be out of luck there.

I can't offhand see a reason why you'd ever cast a light/darkness spell at
anything other than maximum power. If it's dark, you want to see normally, not
see your hand in front of your fact but no further. In addition, the amount of
code out there that looks at the brightness of light is very small (aside from
how quickly vampires turn to smoking piles of dust, I don't know of any "how
bright is it?" code out there), however, I guess I can add it since the only
result this will get is more sps wasted when you realize how little this
helps.

I have only taken a quick look at city lamp code, however, lamps have the
advantage of being immobile objects. Light/darkness on players moves pretty
much constantly. The amount of lag caused by glowing balls of light/darkness
screwing up the city maps could be terminal, so I'd recommend against it.
