strung together this:
Probably not a good idea.
Oh really.
Yes, really.
The current for a LV fitting will be some 20 times that of a mains one,
and the heating for a given contact resistance 400 times.
What significance would the current draw be then?
The contacts of the mains lamp may have been designed for a much, much
lower current (lower pressures, smaller contact area) than the LV ones.
If you exceed the designed current by a factor of 20, then the sockets
can just die.
Much as if you tried to pull 260A from a mains plug.
Yes, but the contacts are irrelevant here - they will have to be binned and
replaced with the standard LV connector (completely incompatible).
Dichroic/non-dichroic may be an issue, but not connectors.
This is in the assumption that the tails of the LV connector are connected
directly to the feeding LV cable or mini-"transformer", and that there is no
built in switch or other intermediate connectors (which should not be used
for LV).
