like in Minecraft, there is light blocks that normally you cannot see but they do light up the room.
my idea is having a whole new section of the tech web with light blocks going from -5 to +10 light blocks (so 15 new blocks in total) the - light blocks will make the area darker (the lower the level the darker) and for the + lighting blocks will light up the area (the higher the level the brighter)
the only way to see the light block is holding the light block or having it in your hot bar. but they don't have collision.
this will be a creative only item.
