Is your feature request related to a problem? Please describe.
I need to use the high-powered lamps to cover as much ground as possible, but in addition to this, I need these lamps to respect solid walls that would block normal lights.

Describe the solution you'd like
I would like to see a variant of the omega (and lower variant) lamps that respect light obstructions. If this is already possible, please let me know how I can make them.

Describe alternatives you've considered
There aren't any alternatives available for 1.15 as far as I know

Additional context
I think the description is self-explanatory.

Making lamps that respect solid walls can be hard. I need to make pathfinding algorithm but I don't have much time to work on it.
I don't close the issue. Thanks for suggestion!

yeah like the quantum lights mod (https://github.com/DarkMorford/Quantum-Lights) from 1.12.2, thats was great.
I would be really very grateful for that, because currently I have whole biomes illuminated 😅
