Found it, but it was rather expensive.
It was a bit of a suprise when I saw the inside; the light came from two LED- strips!
I stil had some left at home and made my own LED- light, and was suprised by the result.
Step 1: Prepare the Wood
Step 2: Prepare the LED-strip
Carefully peel the protection off the copper contacts.
This requires careful preparation, see that the copper on the LED-strips is clean.
Solder wires at the strips.
After testing I finished the strips with heat schrink. This is not necessary, isolating tape is also good, but I prefer this.
Step 3: Stick Together
I also used a glue gun.
This was still not good enough, the LED-strip went loose.
I made three perspex strips with a hole, and fasten them. (I used clear material because I want the full rendement of my LED's.)
Step 4: Finish!
I myself am very glad with the result.
Totally made from leftovers of previous projects I made a luxury light above my new built workbench, with low energy consumption and remote control!
