Hi gang!When I hopped onto EMC for the first time we were still on 1.7 (and I really disliked the idea of going to 1.8, look at us now!) and in 1.7 we had very limited light blocks. A torch, glowstone, jack'o'lantarn, and lava (plus fire). That was basically it. I know: there were blocks such as a redstone torch (dim lit), redstone lamp (not on all the time) and of course beacons, furnaces and redstone ore can also emit light. But you don't use those blocks for light necessarily When 1.8 hit we got Sea Lanterns, when 1.9 hit we got End Rods and right now there's a nice diversity of light sources which we can use.My favorite are end rods. I think Mojang really did an amazing job there because you can use them in all sorts of ways. A friend of mine devised a way to make them look like light tubes, I've seen them used as both light sources and parkour areas and yeah... very versatile and I also think they emit a better usable light than other blocks (could be my imagination).I lit up my small farm with end rods and I think it looks pretty good!Obvious question: what is your favorite?
