I know we had this discussion in regards to installed racks, and the answer was that 2.4ks don't cost that much extra over 1.2ks, so they're advisable, and quite standard. From my searching around it looks like the dimmer pack market is split between 1.2k and 2.4k. Looking at SmartPack prices on Production Advantage, it appears that 12x1.2k and 6x2.4k are pretty equivalent in cost. In regards to Dimmer Packs, what would you prefer? At the same cost: Less 2.4k / More 1.2k Edit: And please post and outline some of your thoughts.
