Ty Glen...! This is very interesting since the Vials are always "Full Lume" then they would Naturally beat out any other form of Lume on every watch other than Those using the Vials...Great Info  Here's an article I borrowed from another website describing Tritium Vials, like those found in the Ball HydroCarbon, Luminox etc....

"So, what exactly are the tritium vials? In brief and very basic terms: tritium vials (gaseous tritium light sources) are sealed glass tubes, the inner surface of which are coated with phosphor. The sealed tubes are filled with gaseous tritium which emits electrons which in turn excite the phosphor, causing it to glow. Thus, no external light source is required to charge the tubes and they will continue to glow constantly. For how long? Tritium in this form has a half life of 12.3 years which basically means that half the existing glow will be lost after a further 12.3 years. For all intents and purposes, one could expect a useable glow from the tubes for 12 to 15 years from new/fresh."

 
Guys,

I apologize for the basic and perhaps stupid question but I couldn't find anything on a search.

When watches are described as having a "good lume" what exactly does that mean.?

a) lasts for 4 hrs after being in the sun all day?

b) lasts 6 hrs?

c) you're right,  that is a stupid question :)

thanks as always boys
