Fluorescent street lighting

It had unusual markings-I think it included an amp rating but no wattage; had a mogul base. I finally tried it in an old lamp with one of those bases. As the educated on here could guess, when I flipped the switch there was a flash of light, the filament burned out and the circuit breaker tripper. I later learned it was used in a special type of street lamp circuit-series string, I think. I still have the bulb and package because it's kind of neat to look at.

Considering that they were used in circuits that run at such high voltages, and that it tripped the breaker, I doubt it's burned out. Have you seen a broken filament or checked it for continuity?

Hard to tell what such a reply is supposed to suggest but it didn't surprise me.

The label is fully intact and more than just printed letters, and I know where the company was based so it shouldn't be that hard. Besides, information for many things Canadian is very difficult to find on Google so I'll just have to check other sources.
