It was a whole hose square D surge protector, it fits into the first 2 breaker slots. It's still lit up green! It wasn't a lighting strike, a tree hit the line one house down and I believe one of the hots crossed or something. But I'm a huge fan of CAFCI breakers, as they protected a lot of stuff, where as regular breakers + GFCI receptacles just fried.
Not to get off topic from the original poster, for outlets, honestly a single receptacle per circuit is sufficient, if you want to do a double gang (4 outlets) for each circuit you're in overkill land, but you're going to use power strips for safety, so the number of physical outlets is inconsequential. The wiring is key, make sure to run 12 gauge at a minimum so you can have 20 amp circuits instead of 15 amps on 14 gauge wire. 2 circuits is fine, realistically unless you're doing metal halides 1 circuit is probably sufficient, but 2 is safer.
