I was noticing the recent trend of illuminated reticles amongst the various manufacturers and it got me to thinking. How reliable are they and what would the serviceable lifespan be? Many of us shoot with scopes that are 20- 30 years old or more. Would you expect that with an illuminated scope? If the illumination fails, is the scope still useable or is it now a paperweight? Anyone have one fail at a crappy time?

How about batteries leaking from sitting unused? I think most use the coin style batteries, so not sure if it's an issue with that type.

My only experience with an illuminated scope is the Trijicon Accupoint that uses fiber/tritium. I've had it about 10 years now and it's still bright, but I understand it's pricey to get them repowered. I just bought a second one in 1-6 x 24 and expect it to serve me just as well, but it got me to thinking about scopes with electronics.
