One would think that there would be plenty of hot air accumulating
near the ceiling, but that wasn't the case. That's where the fan
ducts were located which helped to cool the lights. Few of those
lights ever burned out.

The marquee lamps were mounted on a vertical structure, with the lamps
pointed horizontally.

Vertical mounting for a GLS lamp seems to give a better life than other
orientations. A rough service type may have had a better life in this
application.
