We just got some brand new Birdies and MR16 lamps to go with them. Yesterday I put an edison plug on one and when I plugged it into a regular wall socket the lamp exploded like a gunshot. I thought, bad lamp, so I tried again. Same result. Then I thought I wired the plug wrong, so I tried a new plug. Same result. I thought it might be that unit, so I wired a different one. Same result. So I thought it was my wiring, so I had our LD wire it and same result. Then I thought it was the outlet, so I went to another room and tried it again. Same result. We even brought another lamp from another space to test. Lamp flared, then went out. Any ideas?
