Step 1: Materials and tools
I use a leg from a cheap aluminum tripod, (a "C" channel aluminum profile will do the work too)
Of course the only expense, the LEDBERG from Ikea for $12.00.
Double Side tape
Small saw or dremel tool (to cut the channel)
Drill and bits
Screws and nuts.
Step 2: Assembly
It was just a matter of putting together the strip into the aluminum channel.
the nice thing of the Ledberg is that the on/off switch is on the cord close to the light assembly so there is no electrical work involved.
The lamp have 3 strips of led's that can be connected together to the power strip. I use only two of them.
the measure of each of the individual strips is around 10" plus the connection to the power a couple of inches more.
I've cut the Aluminum channel 22" long to fit the 2 strip set up. the thickness of the strip is around 3/8" which fit neatly into the channel.
I set it into the channel with a few pieces of double side tape.
I drill a couple of holes at the bottom of the channel to connect it to the base, as well some cutting to allow the lamp to go up and down.
