A rather high wattage for an S11 envelope, nearly double that of the 40w high intensity intermediate based bulbs. Likely for a certain type of slide projectors. Found at an sale.

Hadn’t yet powered it, I could imagine how extremely hot this one will get.

Long live the great old 20th century quality in electrical & lighting products!

I have this bulb! I powered mine up.. Inside a fixture that was originally meant for 12V RV interior lighting.. it made the metal on the fixture start smoking....

Wow! Hope that didn’t do to much damage to your RV fixture. If I power this, likely from a low voltage source or just continuity test to see if filament is still intact. Doubtful running this one on full power.

Long live the great old 20th century quality in electrical & lighting products!

UPDATE the designation is PH/111A. The P is likely misprinted to appears as an F.
