A problem with Points of Darkness is that once the players have gained a few levels by confronting darkness, it is often tempting for them to simply throw their weight around in the normal areas, where opposition is quite light compared to the dark areas.
Of course, this only is a problem if you object to it.
My main objection is that both PCs and their "points of darkness" environment feels like it is removed from the main world - the PCs become strangers in their own world, governed by their own rules and gauged on a power level normal people cannot achieve. Of course, this is always so in DnD with it's explosive power development over levels. This is somewhat less glaring in a points of light setting because the "lab environment" is so ubiquitous there - all the player ever really encounter are monsters.
