I am trying to control an el-cheapo 2 bulb 4' florescent Shop Light with
an MS16A Motion Sensor and an RR501 Transceiver.

The shop light has a 3 prong plug, but the Transceiver only has a 2
prong receptacle, so I used a 3 prong adapter to plug the shop light
into the Transceiver.

What I'm finding is that (99% of the time) when the sensor sends the
signal to turn off the Shop Light, it turns off and then immediately
comes back on. The Transceiver goes click-off-click-on.

I've experienced this problem with modern fluorescent lights. My
un-elegant solution was to have a plain old incandescent night light on
the same load. As for grounding, in many cases it's important with shop
lights. Run a jumper wire from the outlet ground to the pigtail on the
adapter plug.



Thanks! I tried the incandescent lamp and it solved the problem.

You are assuming there's an outlet ground. Bad assumption. :-(
