Here is a photo of several CD 154 colors on my light stand that I use for photography. To the upper right is a really beautiful Depression Glass Green CD 154 McLaughlin I recently acquired from a west coast collector. He was not quite sure of the color at first, nor was I, describing it as having much more of a yellow cast than the more common apple or lime greens. Although "Depression Glass" comes in several shades or tones of green, the more common is the bright yellow-green that resembles very closely some of the later dark vaseline glass colors. Don't know yet if this one will actually fluoresce under ultraviolet (black light), but considering there was lots of fluorescent vaseline glass produced in the same period as these insulators, I'm keeping my fingers crossed.

Were there any true fluorescent insulators known made by any of the major manufacturers that have been verified and cataloged ?
