I have a few MR16 bulbs (including that SORAA) LED, they are all low voltage AC input. I want to be able to turn them on and off with a logic level signal.
While I can drive with DC and simply use an open collector/drain transistor, I do wonder about the long term reliability of them with DC...
... but what would people prefer to do? Assume 12VAC (60Hz) and 12VDC are both readily available.
option 1: as above, drive with an open collector/drain DC with DC control.
option 2: use a TRIAC to gate 12VAC with a DC control
option 3: Use a relay to gate 12VAC.
option 4: use an H-bridge and drive with DC control
option 5: Take the MR16 LEDs apart, rid the rectifiers, use DC direct.
The higher number options are getting less and less desirable due to cost...
And is there another option that would be even better?
