Obtaining a large amount of lava in Minecraft

I want to use lava as a lighting system, but that will require a lot of lava. What's a good way to move a large amount of lava? I'd rather not make many buckets and have to travel back and forth. So far I think it's my only option since I don't think it's possible to make unlimited lava source blocks. Oh, and if it matters, I'm on the Xbox 360 version.

Unfortunately there is no way to make infinite lava in the Xbox edition of Minecraft.

Your only option is to make buckets and carry it. To speed the process up, use more buckets and consider using the nether as a source of magma.
