What we do is take the IKEA JANSJÖ worklamp, and combine it with the FÖRHÖJA wall cabinet to create the AMAZING Bedside-Table-Cabinet-Lamp.
1) Remove lamp from packaging
2) Measure out where to drill holes
3) Drill holes (this means using a 5mm drill bit, and widening the hole enough to get a snug fit - a 6mm drill bit made the hole too big, so beware!)
4) Insert lamp
5) Insert screws
6) Plug in lamp, and enjoy!
