Longbow Mini Problem?

[Warbird]

I have a Longbow Mini flashlight with what seems to me to be a slightly yellow hotspot.I really like this light and want to keep it but is it normal that the hotspot should be a yellowish to greenish tint?

I guess it is the Luxeon Lottery whether it is to be white or not. Does anyone know if I can send it to Longbow Gear in AZ. and get an Exchange?

Thanks
Jim
