I ended up with a set of Troy's tritium buis. However, before i got them I didnt see too much information or pics out there on them. I figured I would share a few if anyone else has been debating purchasing them, as well as a few of my first impressions. Its not easy to demonstrate their capability in pictures, but i will try to share what I have. Bare with the lack of clarity please, the lack of light makes it difficult for the camera to focus.

This is the rear sight as it would be seen during normal daylight use. As you can see the tritium just appears as two small white dots.

As ambient light becomes dimmer, tritium becomes apparent. Note: the glow is distinctly brighter and sharper in person.

As you can see, it does not require total darkness for the tritium to be visible. It becomes useful in lowlight coniditions where you can still see you front sight pose but this makes its aquisition considerably faster.

If you haven't already read, the two rear dots blur out if you approach nose to charging handle. They do still provide a situational awareness to whether or not you are lined up. The dots are big at this point but usable. It is possible to back off slightly and use the rear tritium more like a handgun sight, by lining up the three dots opposed to using the rear aperture as a ring. Using them in this manner the rear dots stay small and tight in appearance. It might not be ideal but it will certainly work.

Here's an example of very low light condition. Again, the dots are much brighter and crisper in person

And finally, near no light. At this point i can see nothing in front of me other than the tritium on the sight. They look like green globs, but they can still be aligned vertically and horizontally.
(UPDATE) I've taken additional pictures of several of the sight's unique features that may be of some interest.

As you may notice, the aperture on the black tritium sight is significantly thicker than the original which is on the left, this is to encase the tritium, and is often not easily seen in most of the industry pictures.

Take notice of the front sight post... FYI, the tritium is only on one side. Additionally, due to its design, it can only be used in 2 turn increments. The length of the post prevents the user from using each turn (unless you turn it sideways which would make it giant). * Take note: if you turn the FSP to the non tritium side... There would be a bright green dot in the direction your facing... Something to think about...
Please feel free to ask any questions if you have any and post any of your own experiences with the sights. I've been adding a few more pictures below with some of the replies to go a bit further into detail; scroll down to see and check back for more later-
