The Green Torch is a colored torch crafted with Emerald that may be used as a light source for an NPC room, or simply as decoration. Like other torches, it can be toggled on and off when connected by Wire to a Switch or similar triggering device. See Gems for more info on Emerald. It is the dimmest gem-crafted torch (at only 20% brightness of a regular torch). File:Terraria - Colored Torches Terraria HERO
