I have a ceiling light in my sitting room that takes 10 G4 10w halogen bulbs, the bulbs dont last long so i thought id buy some led ones to replace them. I bought G4 2w ones I put 4 in and tried them and it worked great, i then changed all of them and all bulbs flickered and went off. I tried them one by one and now none work. i even tried my old bulbs are they wont work so i have no idea whats happened and im now in darkness, can anyone help please
