Newly Enlightened
The H600Fd Mk IV I received from Zebralight has a noticeable green tint.
It's not clear to me if the tint is an artifact of the LED type that the light uses, or whether the tint is a factor of losing the tint lottery.
In any case, I am a tint snob. Which means I'm conscious of tint when using the light. Typically, I use it for much of the day and night. It is the main source of artificial light here.
I am also a tint slob. I don't let the tint get to me. I imagine the daylight coming out of the lamp is like sunlight filtered through a verdant leaf canopy.
Now, magenta filters out green. A while back I got some filters from Lee and from Rosco. Links in this thread to how to get a swatch book of filters no longer work. Below are updated links.
Flipping through the Lee swatch book, I found:
Bingo!
I cut off a piece of Quarter Minus Green/magenta film, trimmed it to attach to headlamp lens, attached with my favorite method of using parafilm, and voila! tint was mostly subdued. Whites now appeared...well, white.
BF (before filtering): peering into light, green tint was apparent, especially when catching the light from edge of lens
AF: Light appears mostly white.

Update
The filter color is a light magenta. That is why it is called a "Quarter Minus." There is also a "Half Minus." Still, it is slight overkill in this scenario. What is really needed is an "Eighth Minus." The "Quarter Minus" filter eliminated the green tint, replacing it with just a hint of magenta tint. An improvement, but still not there.
I used a pin from the sewing kit to remedy the overshooting of the goal. Tiny holes poked in the magenta filter allow a better balance of magenta versus green. To quote Goldilocks, the beam now seems just right.
