Hoping a seasoned veteran TV guy can help me here

I typically work on arcade monitors and several of the CRT have really bad burns. I have a few TVs that I'd like to swap the tube out, but most in the arcade monitor world really only focus on size, yoke specs (impedance and resistance) and neck socket. I think there's other spec that need to be reviewed for compatibility. For example:
G2 voltage
Deflection angle
Phosphor/finish types (I've seen some face plates which are dark and others that are more lighter silver)

I have problems finding datasheets for CRT and the ones I can find, I don't know what some of the data points mean. For example, I keep seeing "Light Transmission of face glass at center" and has percentages.

Any help with "Light transmission," finding data sheets of CRTs past 1999, or other industry references/tricks/pointers would be greatly appreciated.

That is how clear the glass is. What percent of the light makes it through the class.

There are many different types of coatings for CRT glass. Some reflect light from the room and others do not. There is flat vs matt. etc.

Thanks for the response. Just curious, some specs are lower percentage than others within the same tube family. Wouldn't you want all the light to come through?
