So I went and pick up some Giesemann bulb from chance, and got home to replace my old bulb. One of the old bulb is actually new from end of Sept, Giesemann super purple ( Purchase from MD.) So this is the second time I touch the bulb to change it to the 3rd row. So the metal thing that connect to the socket from the bulb is lose, and if I tightening it. It's in a different position then other side. Do Giesemann cover in warranty?
Bulb is purchase from MD, not Chance.
