In Pocket Edition Alpha versions 0.5.0 through 0.12.0, glowing obsidian was created when a nether reactor structure was active. As the nether reactor's functionality was removed in version 0.12.1, add-ons or inventory editors are the only ways to obtain glowing obsidian in subsequent versions. It is not in the player's Creative inventory and cannot be obtained using commands.
Glowing obsidian emits a light level of 12.
