LambDynamicLights [Unofficial NeoForge]
by LostPattern
Players who explore dark caves can carry a torch, and LambDynamicLights lets that light spread around the holder in the game world, as an unofficial NeoForge port.
What it does
Entities that hold an item which emits light as a block produce light of their own, so a torch carried by a player lights the area around them. Dropped items that already emit light as a block also give off dynamic light on the ground. Burning entities, blazes, magma cubes and spectral arrows emit light too, with spectral arrows giving only a faint glow.
Light from items follows the light level of the matching block. A settings screen controls how smooth the dynamic lighting looks, and the mod also works with some modded items. The author suggests pairing it with a separate rendering optimization mod for better performance.
The mod is published for NeoForge only, with builds covering 1.21 – 1.21.1 and 1.21.1 as the latest file, dated 2024-12-10. It is client-side only, so servers run without it, and players who want dynamic light install it on their own client. The code is under a custom license and is not open source. The source code and issue tracker are public.

What the author says
It's dark outside, extremely dark... You can't see a lot in the darkness, you wish you had a torch, or a lantern to hold and see in the light... And this is now possible with this mod as it adds dynamic lights to the game. You can see in the darkness thanks to your torch now!
