230V Dummyload

Some time ago I came across 2 loose Incandescent light bulb. I sometimes use these to test dimmers. But I find it annoying that they roll of my desk and are so fragile. Therefore I made a case around them.

For the front I used a layer of red pvc on top of blue pvc. By doing this it reduces the intensity very much. Now I can look directly in to a 100W lamp.

Picture with the 25W lamp burning:

I drilled a 74mm cooling hole on each side of the case and glued some mesh to it.
