Electronic transformers do not work with LED lights. When replacing your transformer / power supply with a new one, we strongly recommend you purchasing a dedicatedLED power supply / transformer. The right kind of transformer is an investment to guarantee the maximum lifespan of the LED lights. This would need to be a constant voltage LED power supply / transformer.Unlike electronic transformers, commonly used for halogen lights these do not have minimum load requirements, but do have a maximum so make sure the sum of Wattage used by your LED lamps or lights is less than the maximum rating of the LED power supply / transformer. To maximize the efficiency and lifespan of your LED transformer keep the total power consumption close to 80%.
Please note: LED power supplies / transformers are design specifically for LED lights.
