The Ikea Jansjö LED lamp

for lighting a 3D printer for webcam streaming. It's inexpensive ($9.99 at Ikea or $14.99 from Amazon) and has that rarest of things, a gooseneck that is generously long and actually works well. It has a dual-screw mount to its base which is clever in that it prevents the lamp from unscrewing, but which makes it problematic to mount to random surfaces (unless you get the clamp version, which I dislike).
My shop is in an old brick building with many windows so it doesn't lend itself to wall-mounted shelving. I make (well OK, my husband actually makes them but I design them) desktop shelving units with perforated square tubing and angle iron from SteelWorks, which is available at Lowe's stores and also from some Amazon sellers. It's not cheap but it's incredibly sturdy and allows for attaching all kinds of stuff.
This Thing mates the Jansjö lamp to Steelworks or other material with holes on 1-inch centers, freeing up desk/workbench space that would otherwise be taken by desk lamp(s). Having the lamps anchored solidly also makes repositioning a one-handed affair.
The angle iron on this bench has 0.4" holes for 5/16" bolts. 5/16" was a bit beefy for this little part and I already had a nice-fitting hex-head recess for 1/4" bolts, so I used that. The result is that the bolt fit in the holes is sloppy, but the protrusion in the center of the back of the part engages a 0.4" hole snugly and holds the part in position.
The holes are slightly below center to match the alignment of the angle iron and look more aesthetically pleasing.
The hole on the end is a somewhat frivolous and not too well thought-out cable grommet so you can feed the Janjsö's power cord through it. Unfortunately there's a switch and a big plug on the cord so to feed it through the hole you need to cut and splice the cable. It's low-voltage so there's not much safety risk, but you do have to get the polarity right since this is after all an LED lamp.
As posted here, the cable grommet is on the right.
ungroup the part, drag the grommet subassembly to the other side, rotate it 180 degrees, and stick it back on.
Or if you don't want the grommet thing just delete it.
