I bought a nice big Ott light for my sewing area quite a few years ago - worked for about a year, then one day it just didn't work anymore. Tried a new bulb, nothing. Bought a new cord unit with the black box (can't think of the name right now) - still nothing. It's still sitting around here, because I figured one day it's going to magically work again, but I won't spend that kind of money again. I finally bought a similar light at Big Lots for $29. Works just fine.
