We did a job a few months ago and installed cove LED lights strips (38 feet in length). The cove lighting is in a public restroom and is on an occupancy sensor switch. The transformer has failed twice in the last 6 months. The LED light supplier who also provided the transformer appropriate to the light strip says the frequents on/off of the light strip is causing the transformer to fail (it flickers). They claim that the LED light and transformer is designed to stay on all day, not to be turned off and on constantly. Does this sound right? If the supplier is correct I'll have to tell the owner, but if they are BSing me I need a new supplier. Thanks
