TYOH in a modded Longbow.
I think my friend Robocop has a TXOHorJ in a Firefly that looks very similar though we haven't had the chance to compare them.
The one thing I've noticed different about this one is that every other time I compare two LEDs on a wall, both will show color variations.
My TYOH looks WHITE. All the time. It shows a little shift side by side very close up, but usually the color variations of the other LED will stand out much more.
That may be due to the difference in brightness, since it is my brightest LED light, but I've never seen an increase in brightness make this much difference. The biggest test is on a map with multicolored divisions, but standard markings. With this TYOH, all colors are rendered equally, with none being emphasized or washed out (for instance, my TYOK in another light washes out blue and to a lesser extent green, while emphasizing red and yellow).
I can't think of anything being demonstrably whiter than that.
I'm hoping my other two YO bin emitters are this good whenever I get around to putting them in something.
