Candle

A candle is a light source. There are 17 different candle variants, one uncolored and 16 colored, that follow the general colors of wool. Candles can be lit with flint and steel and extinguished by water or by the player. They can also be waterlogged, but cannot be lit while waterlogged.

Obtaining
Candles can be mined using any tool, or without a tool.

Light
Candles can be used as a light source, emitting light like a sea pickle. A single candle emits a light level of 3. Up to four similarly-colored candles may be placed in one block, with each candle increasing the emitted light level by 3, for a maximum light level of 12. They also emit fire particles.

Candles are not lit when they are placed, and must be lit using flint and steel, fire charge, or any flaming projectile. Candles may be waterlogged, but waterlogged candles cannot be lit. Lit candles can be extinguished using water or by the player with the candle.

Cakes
A single candle of any color may be placed onto an uneaten cake, after which it acts as a normal single candle. Only one candle may be placed on a cake. If the cake is eaten, the candle falls off.

Trivia

 * Candles are similar to the concept of burnt-out torches from the Halloween Update.
 * Using the command  allows for a both lit and waterlogged candle.
