Deciphering Tru-Glo sights

So, I'm interested in some good, day/night, preferably glow-in-the-dark sights, for my XDs EDC. I'm trying to decipher the different levels of the Tru-Glo sights...

Only some of them say "glows in the dark".

TFX-PRO has a ring around the front sight; does that glow in the dark as well?

Do they all?

What's the difference between TFX, TFX-pro, and Tritium-pro? The writeups all look the same to me...just different wording for same/similar features?

The way they do their graphics, it almost makes it look like they have a glow/tritium dot at the front end of the fiber optic tubes along with the 'sunroof' to let ambient light in, to light the fiber optics...is that the case? Or is that just the way they do their product images?

Is (forgive me) "tritium" another word for "glows in the dark"? Or does it need to be light-recharged in order to glow? I've done a lot of stage and theatre work where we use "glow tape", but it needs occasional recharges under light, in order to glow again; is tritium eternal-glow, or does it need recharging?

I have an instant-on laser on my XDs...but I want to have the best possible iron backups I can, in case the laser doesn't light when I draw for some reason, when I need it most.
 
Fiber Optic are fiber optic (no glow at night)
Tritium just Tritium
Tritium pro have tritium and hi viz ring around the vials.
TFO is tritium and fiber optic
TFX is Tritium and fiber optic but everything is encapsulated making them tougher think TFO but milspec. Plus they have white ring Around the front vial
TFX pro same as TFX but orange ring around the front.
 
Tritium is a radioactive material that glows in the dark IE night sights. They have a 12 year service life and do not need recharging.
The combination of fiber optic with the tritium means they glow at night and during the day.
fiber optics only, need a light source to glow IE the sun.
 
Excellent, thank you for the clarification. The XDs has the factory fiber-optic front sight and simple dot rear sight...virtually useless in my natural environment for carry (live sound production in nightclubs - very dark). I'll have a look at the TFX and TFX pro to see if my eyes prefer the white ring, or the orange...and I'll have a look at the Tritium Pro as well since I don't carry in "combat" situations. Perhaps "mil-spec" would be overkill for EDC.

The TFX PRO Day/Night Pro Orange will show rear green with front green and orange ring during the day at night they will be all bright green and very visible. I have these on basically every pistol I own. I might also add they have great customer service.
