This doesn’t make sense since the problem exists in one of two light fixtures. He had swapped the bulbs and the problem followed the problematic bulb.

However, your idea of trying the bulbs in a standard lamp is a good one.

OK, it seems that I have missed that post. If the problem follows the bulb, then it woulld appear to be a bulb problem. BUT there is a chance that it could be a polarity issue. Some switching devices have somewhat polarized outputs. I have blown up a CFL ligh that way.

Yes the bulb was the problem. Bought a new outdoor led bulb and all is well. Thank you again to everyone.

 

One realcaution i that LED lights controlled by either motion sensors, or some varieties of timers and sensors, should be qualified as "Dimmable" because the control device is a triac or an SCR. Some electronic ballast type supplies "do not play well" with other than pure sine waves. Either flickering brightness or smoke escape can result. for some of them. That is especially true for CFL devices.
