3D printed flexibility

Today, I printed a new version of KK001. This light has a built-in 220 to 12 volt transformer. The KK001 trafo is rather big, so the light needed a big space to hide it. The printing of this hiding place took too much time, so I started looking for a smaller transfomer and some months ago, I discovered a very small and cheap LED driver. Now, I could design and print a much smaller ground part for my lights, which I did. Opqrstu3D was very happy with it’s little Chinese princess. Until I used it with one 1 watt LED bulb only. The LED worked for 3 minutes, then it suddenly stopped. I unplugged it and tried again: the same thing happened. The LED was undamaged, but very hot. Opqrstu3D did not write about this this, because mounting a 2,5 Watt LED solved the problem. Meanwhile, I asked Frank form topledshop.com if he knew what was happening and of course he knew: This little princess produces constant current which works fine with 2.5 to 3 watts. At 1 watt only, you need a constant voltage transformer.

Last week, I bought a constant voltage 12 volt transformer at TopLedShop. Today, opqrstu3D designed and printed a hiding place around it and mounted the original KK001 light shells. Again, an example of the wonderful flexibility in 3D printed product design.
