Review on Elco Lighting RP 1B Insulation Sensor by Jessica Velasquez

Does your drop ceiling flash and turn off or not turn on even though the circuit breaker is not off? This sensor is to blame. They are standard on some types of lights to detect overheating and turn off the light before a fire starts. They may become moody or not open up as they age. The good news is that they can be replaced without having to buy a new light. Make sure you check what you have before ordering. To check if the problem is with the sensor, temporarily disable it and see if the indicator lights up.
