I think it was recent, but it was like a two panel thing again just like with the yellow ring. I can't remember which comic it was in since there are so damned many lantern comics at the same time now.
Also the Batman black lantern thing is sketchy. Yes he had it, but no it technically wasn't him, but yes at the time it was still him since they hadn't decided how to write Batman as back yet. I believe at that point it was kicked around he'd get Lazarus Pit action to return or something so it was both yes and no that he was a Black Lantern. Retroactively once he was back it was changed to no to cover the return story. It was left open for that reason.
