I have electronic transformers rated at 12vac running my kitchen lights they are 12v 50w halogen down lighters. I recently purchased a 6 watt 12v LED marke3d as AC/DC lamp to use in these fittings. Bench testing this LED lamp it works perfectly on 12v either AC or DC. However it does not work on the electronic transformer. I have measured the output of the transformer with the 50watt halogen lamp connected and my digital meter reads 56vac Can anyone lead me to understanding why? Thanks in advance
