I created this blend for weekend challenge #548 over at

The theme for that week was: Soviet Technology.

After some searching, I discovered that Russian Oleg Losev reported creation of the first LED in 1927.

So I decided to model an LED light. I used Blender 2.69 and rendered in Cycles.

The modeling was not that difficult, but getting the materials to do what I wanted was a struggle that I feel I didn't quite meet. However, I am still somewhat pleased with the final result.

This image is straight out of Blender with minimal compositing, and no additional tweaking with any external image editors.

    Very nice. One observation: the cathode lead should be shorter than the positive one (or viceversa). Regards.

    Thanks oldtimer, for the compliment and the observation. I just went and looked through all of my reference images and noticed it. most of the images I used were close ups that cut off the leads before they ended but at least two of them showed the varying lead lengths. Good catch!
