This post is mostly a reminder to myself, and hopefully assistance to anyone else looking for the mechanism to convert a regular exterior/outdoor light fixture to a motion sensing fixture.
Rona carries the Heath-Zenith adapter sensor, model #HZ-5210-GR, for $34.95.
I’m considering adding the adapter to a Rona fixture, the “Martes” lantern by Globe, $40.99 (though it was under $40 a few weeks ago when I bought seven of them). I do like the look and the price point, though I’m not crazy about oil-rubbed bronze as a finish — I’d prefer black, but apparently that’s too boring, so ORB seems to be everywhere. I’m hoping when the lights are up they’ll read black, maybe with the help of some Rustoleum spray paint if not in reality.
