Bottled Light
by TechMonkey
Bottled Light lets a player place invisible light sources that glow at level 15, and dilute them with empty water bottles to dim them.
What it does
A placed light is an invisible block that lights the space around it at level 15 by default. It keeps a collision box and a visible model, so the block can still be found and interacted with. Each empty water bottle used on it lowers the light level by 1, which lets a builder dim it step by step from the maximum.
Holding the item makes nearby placed lights show faint sparkles. Those sparkles are drawn on each player's own screen, so other players never see them and the hidden block stays hidden. The effect helps a builder spot lights that are otherwise hard to find, and changes nothing for players who are not holding the item.
The mod runs on Fabric in both single-player and multiplayer, so the server and every player need it. It is published for 1.21.10 and 26.3, with 1.0.2 for 26.3 as the latest file, and it is released under the MIT License as open source. Its source code and issue tracker are public.

What the author says
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…
