Anyone have any documentation on the DALI protocol for fluorescent lamps? It's apparently an addendum to IEC929. I'd like to see more about it before considering writing some PIC code to talk to DALI ballasts. A Google search (DALI fluorescent) turns up lots of stuff saying how great it is plus something about Salvatore Dali and fluorescent bunnies... Thanks!
