The one I got has a 6 month warranty. I intended it to be a stop-gap measure until I receive the one that my warranty is supposed to provide - how ever long that process takes - and then to use it only as a backup. I'd hate to use the 6 month bulb for 6 months just to use up its warranty time only to find that it's gonna blow on 6 months + 1 day. I've only got til 2/2010 for the 3 year term anyway, so I guess it doesn't matter.
