Candlestick Holders

Candles are very useful. They are not nearly as heavy as torches, smaller, and have the benefit of being potential "containers" of magic. The big issue with candles is that they give off a smaller light radius than torches, we'll say half the radius for simplicity sake. They do, however, burn for twice as long as a torch would.

That said, you need a proper holder for candles if you wish to use them in a dungeon environment. here are some examples of Candlestick Holders:

These can also be used as inconspicuous treasures - A very fine design candlestick holder made out of gold, silver, platinum, or embedded with gems, etc, would be an excellent valuable treasure for adventurers to find and sell.

As far as magic goes, a "Candle of Protection from X" are the most obvious use - the light created from the candle is what bears the magic and encompasses the sphere of protection magic from "X" while lit. Here's an example of a "Candle of Protection from Undead"

Sanctified Candle: Protection from Undead:

While the Sanctified Candle is burning, any and all Undead creatures cannot come within the 15' radius sphere of light illuminating from the candle, whether or not there is any other light nearby or crossing into the candle's light.

Any undead the light illuminates upon will immediately take 1d4 points of damage and is "turned" as if by a 10th level Cleric for 2d6 rounds. If the affected Undead creature cannot escape the sphere of illumination of the Sanctified Candle, it suffers an additional 1d4 points of damage every round that it remains illuminated.
