THere were 3 standby fittings in the pile, but they are not being retained as standby, so I got the lamps. Interesting in having a E14 base on a 250W lamp.
I guess the reason for so small socket is the desire to save space in the lantern and the short expected burning time (only the restrike time of the main HID source, so few minutes), so the thermal inertia would keep the temperature at reasonable level.
These are halogen intermediate lighting lamps, that are connected to the ballast of the HID lamps, and turns on when the HID lamp, shuts down because of a power interuption or cycling.
Usually used in hi/low bay fixtures.
Double ended halogen lamps of the same wattage are more common in Israel for intermediate lighting of HID fixtures then screwbased lamps like these.
All the Best
