Wouldn't you know it, Ikea Canada doesn't appear to stock that Tertial lamp with the table-edge clamp... they have lots of nice looking swing-arm work lights, but not a single one in stock at Ikea Canada appears to clamp, they've all got big bases instead.
I have a pair of swing-arm lights, one clamped to either side of my painting/modelling table, each with a daylight-balanced CFL putting out the equivalent of 120W. Both of them are broken in different ways, though, and I've been shopping around slowly for replacements for a while now.
