We need more info to help. Are they solar, low voltage, line voltage? Are they connected to a timer or ambient light sensor, remote control, controlled by a smart controller of any kind? Do they all turn on/off at the same time, or each turn on/off at different times, or a group of lights turn on/off together? How long are they off before they turn back on? Is it a consistent time or it varies each time?

OK I went to Lowes about a year bago and bought a set of six portfolio 11 watt lights with a reansformer wire. They worked fine

The timer can be set for any nember of hours and has a light sensor. I set it to stay on for 5 hours.

While it is on, it probably goes on and off itself every few minutes.It stays off probably less that a minute

Hello David,

From what you have described, the issue is more than likely related to either the photosensor you are using or, the low-voltage transformer itself. Considering that more than one light is being affected, this leads us to believe that the source of the problem stems from the power source portion of the design. I would recommend trying out a new photocell device before attempting to replace your transformer or any fixtures.

Hopefully this helped to provide some insight!

I would remove or disable the photocell and timer and see if it affects everything. Try a different outlet or extension cord if used. I suspect its a failing transformer, but we’ll rule the accessories out first.
