John Timberland 150W Landscape Transformer with Photocell unit
So the 39549 - John Timberland 150W Landscape Transformer with Photocell unit only lasted 6 years in a protected part of our front yard. I would expect a unit like this to last 15 to 20 years. We're now ordering another transformer so we don't have to rip out the lights and start over again.
