Ah, okay, that might not work for you then. I'm sure other stores offer a guarantee as well though. Just check that out before choosing a brand. The light bulbs we bought are guaranteed (but I forget for how long... I know it's years). There you go. One year isn't bad. It's much better than other types of lights (if they are even guaranteed). I figure that I used to have to replace light bulbs fairly often too, which adds up. So, if these last for years, the extra expenditure now kind of evens out over time.
