About this Mod
Bottled Light
adds a simple way to place invisible, adjustable light sources without cluttering builds.
When placed, a Bottled Light creates an invisible block that emits light level 15 by default. The brightness can then be reduced (diluted) by using water bottles, lowering the light level by 1 per bottle.
To make locating placed lights easy, holding a Bottled Light item causes nearby lights to emit subtle sparkle effects on the client, helping you find them without permanently revealing the block or affecting other players.
