Different animals. The wattage
rating of the "TP-22"
socket is not much of an issue because you can always put a higher temperature rated
socket into a
fixture of lesser wattage - just don't do the reverse. Instead it's a problem of mounting holes of the lamp
base being similar and longer seat height of that distance the lamp
base which will
jack the lamp up above it's normal seat height. This given the lamp itself will have good contact with the pins which it would not on theneutral size. The
neutral wire should be going to the 2.4mm pin, a TP-22
socket has both the same size. See the notes below in pin length in the difference between the G-9.5 commonly called a TP-22
socket, and the GY 9.5
socket. Read the differences
line by
line.
In addition to this note the pin shape. A G-9.5
socket uses two pins of a certain dia. that are the same size. Any type of pin other than this in the GX, GY, or GZ range might or might not be similar and most likely are not. Sometimes they will fit, in this case you won't be able to install your old lamp into this new type of
base, nor will installing a FEL series of lamp work due to it's much longer center of the
filament length and seat height.
Can be done no doubt with some modification, but heavy modification that if it's not perfect will trash the
image. Much easier to just use the proper lamp
base. Sounds similar nowhere near similar.
