Why do you think that light was so expensive? You paid for the replacement light upfront.
Years ago, there was a television manufacturer by the name of Curtis Mathes. They charged the most for their televisions of any TV manufacturer. At one time I worked for a TV dealer, who sold RCA, Zenith, SONY and Magnavox. I asked him about Curtis Mathes, about them being better. He told me that their TVs were no better than any others, you were just paying for an extended warranty upfront in their retail price. I figure SF, with the warranty they give on their lights, and as expensive as they are compared to everyone else, is doing pretty much the same thing.
