i want to convert an existing 120v recessed lighting installation to 12vac mr16 using existing fixtures.
the setup is a room with light switches on either side and three par38 sized cans in the ceiling. the total length of the run is <20ft. my plan is to wire a 120vac-12vac transformer between one of the switches and the cans (i would mount it on a drywall surface), then use an e26 extender + an e26->mr16 adapter.
the wiring is 14ga, so i don't expect there'll be a problem given that total amps will never exceed 12.5 (@12vac). the run is short enough such that i am not particularly worried about voltage drop.
can anyone think of any pitfalls here? my main concern is the 10x increase in current causing the wiring to heat up, but with 14ga wiring (which is theoretically rated for 15-20a) i can't see how that would be an issue.
of course i could do this using retrofit kits, but this way is $150 cheaper, and i get a better-quality transformer.
