30 watts? But aren't the common F48T12's 39 watts? Maybe this is an energy-saving version ?

I assume this is not an energy-saver lamp, but simply a different, and therefore incompatible, type of lamp, like the F96T8 is to the F96T12.

It's possible there is a magnetic ballast in Mexico that's designed for two of these lamps and that's what's in the fixture. These bulbs may also be designed so they work properly on a 2xF48T12 magnetic ballast at a reduced lamp current due to higher operating voltage. They seemed to work properly on all of the booths (there were at least 20 of these fixtures in operation) for the duration of the show. The F48T12 was (is?) very common there; on my first visit, the entire jetway was illuminated with 2xF48T12 wraparound diffuser fixtures. Some had EOL lamps and were rectifying instead of trashing the cathodes like we usually see with slimlines here. Maybe their F48T12 ballast has lower OCV than ours?
