pipesmoker,
From what I read here the 2nd generation module it a little bit different, particularly construction, as photos show they are now using an emiter instead of the star used in my two modules (shown in the DIY post above).
I don't have one of these newer modules, so I can't comment on them being better, but by ugrading the star in the old ones you can certainly make them "better" to you in terms of tint/intensity /ubbthreads/images/graemlins/wink.gif
