While I can't offer any technical specs I can personally offer a small tidbit of info in the form of a great thread. Hazard502 has an awesome thread going on right now about Tri-Adegan Silver and various filtering options right here:
http://www.saberforum.com/index.php?topic=38175.0That being said, the two main ways to filter Adegan Silver are with the US color discs but also Lee color swatches (shown also in the above thread.) As far as specifically which is brighter, Tri-silver with blue filter or single LED Blue, I'll have to leave that for the next commenter
