I'd been seeing these on ebay for a long time and finally gave in to temptation! Probably not made very well but still fun! Should these be used in a certain position?
I almost forgot, one of my other finds along with the sign light that I have posted (that nobody seems to be interested in (according to lack of comments)) the other I found is a coated SBMV Iwakski lamp in A shape!
But check with the datasheet on their manufactrurer's web...
