I have it in service for 4 years one of the LR6 has started to change color and it is a pink hue.
Does anyone know what the warranty was 4 years ago? And is this considered more than 10% failed?
the original store I bought it from is closed.
You may want to contact Cree directly.
I just had the same issue with one turning pink after about four years. I have several others that seem fine. Did you get in touch with Cree and get it resolved?
