First black end cap Westy T-5 I've ever seen.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

Zinc Beryllium phosphor?

The future of street lighting is Induction, not nasty HPS lights or cr@ppy LED lights!
Preheat CFL's should make a comeback!

Probably not, more likely magnesium tungstate which glows blue. Z.B. phosphors were used as a base phosphor in the "white" lamps such as white, cool white, soft white, daylight and warm white. It was replaced by calcium halophosphate in 1949.

Is magnesium tungstate bad like ZB phosphor?

No, it is still used today in Daylight lamps mixed with calcium halophosphate.
