Atlas (sylvania usa made) F40T12 Blacklight blue lamps lit

While british lamp manufacturers listed blacklight blue lamps in their cataloge no examples that are actually made in the UK are known. This leads me to beelive, that these lamps were sourced by other manufacturers. I was pleased when i found this particular example of an atlas branded lamp. What intreaged me was that it was a T12 tube which i don’t have yett. Also very interesting is, that it was made in the USA. I suspect by Sylvania as both companies worked together and shared knowledge.

This brings me one step further in getting all thorn/atlascoulours in 4 foot tubes.
