I came across these shelves a while ago at 33Modern, and I thought that they were a nice combination of shelving and lighting at a decent price. Made of satin steel it should be nice and sturdy, although I have never seen one in person. The top light box has white acrylic panel inserts that cast off a nice soft light. The shelf measures 20" wide, 11" deep and stands 72" tall. Cost is $209 for the the wide shelf (shown) and $189 for a narrower (11" square) shelf. Personally I would rather have satin steel than the crapy plastic wood veneer thats on my Target shelves any day.
Available from 33Modern for $209.
