Astrolux S1 5A emitter - green tinge?

So I ordered this in the warm white, after already having receive the neutral white (3D tint).

The Neutral White has no hint of any colours to it, just a fairly neutral 5000k tint which works fine.
This 5A that has arrived, is definitely around 4000k but has a very distinct green tinge to it. Makes the greens seem much greener and the browns seem greener also.

Is this right? Or should I contact BG in regards to this?
Problem is, on it’s own it’s not noticeable, but when compared to other flashlights that I use as “controls”, it shows up quite clearly whereas the neutral one looks fairly lacking in any sort of colour problems.

I wouldn’t be happy about a tendency to green tint, regardless of the color temperature. But it’s a personal decision as to whether to keep it or return it.

I agree that the XP-L 3D versions of this light are awesome with a neutral neutral.
