View Full Version : LED M6 Pure White Look Yellow after a Year?

I just got a warranty replacement set of M6 Pure White lights and when I went to use them they didn't match my two year old pure whites. My older lights which had all of three months of use had yellowed and looked more like classic white. Has anyone seen this happen? I can understand a little fade but this was a night and day difference.

I have heard this to be quite normal for retrofit led c-9's, especially those left as permanant. in fact, I was told that the blueish white ones get better every year.

I have found it from rust around the metal base of the bulb.
It gets in the bulb and discolours the whole thing.
