An oil lamp is a kind of tool that appears in NetHack. It appears as a lamp when unidentified, and is made of copper. Oil lamps are one of many light sources available.

Generation

When you release a djinni from a magic lamp, the lamp becomes an oil lamp.

The following roles have a chance of starting with an oil lamp:[1]

Characters that start the game with an oil lamp will possess knowledge of the potion of oil.[8]

Description

Applying a noncursed oil lamp in your inventory will turn it on; a cursed oil only has a 1⁄2 chance of lighting each time it is applied.[9]

While on, an oil lamp will light darkened tiles in a radius of three squares around it:

...........
...........
....xxx....
...xxxxx...
..xxxxxxx..
..xxx@xxx..
..xxxxxxx..
...xxxxx...
....xxx....
...........
...........

Oil lamps will remain on for for 1000 to 1499 turns; they can be refilled by reading a scroll of charging or #dipping the unlit lamp into a potion of oil. If you dip a lit oil lamp into a potion of oil, you are likely to cause a fireball.

Strategy

Oil lamps can be conserved by turning them off upon reaching a lit room or area. Cursed oil lamps are simply more tedious to turn on and provide just as much light, so they are not as urgent to bless or uncurse as other items.

Oil lamps can be distinguished from magic lamps by price identification; an oil lamp's base price is 10zm, while a magic lamp's is 50. Magic lamps also burn indefinitely, so any lamp that eventually flickers and goes out is an oil lamp. You can also #rub the lamp a few times to see if a puff of smoke or a djinni emerges, though doing this with a non-blessed magic lamp is likely to release the djinni without granting a wish. Once a lamp is indirectly identified as an oil lamp, it can be type-named to differentiate them from unidentified magic lamps.

History

The oil lamp first appears in NetHack 2.3e, where it is simply called a "lamp"; it was given its current name in NetHack 3.1.0.

Messages

The lamp flickers for a moment, then dies.
You attempted to light a cursed oil lamp and failed.

As the lamp runs out of turns, you will receive the following messages in order:

Your lamp flickers.
The lamp has a couple hundred turns left.
Your lamp flickers considerably.
The lamp has 50 or so turns left.
Your lamp seems about to go out.
The lamp has about ten or twenty turns left.
Your lamp has gone out.
The lamp will no longer provide light unless refilled or recharged.
