For 3-pin connector as shown in the attached picture (file 3518), unit price I much higher than what your PO indicated.
It is THB60/set of male & female (2pcs).
Also, it cannot be fixed to DOT-LESS II fixture, unless you dismantle the fixture and re-solder it.
Why don”t you propoed conventional non-IP plug-in-tiny connector which you originally ordered in this PO? (per attached photo #4762)
