The real question is...why did the fuse blow in the first place. I know a few people, my self included, who replaced the fuse on Lumateks. Only to have the AC socket and cord melt shortly after. Sure it worked after replacing the fuse, but it obviously isn't safe no more. Replacement time if it was me....Lumatek bragged a great warranty, but don't seem to be backing it up. The store, I got mine had to replace mine with another brand. The Lumatek rep is avoiding them, I was told.
