Some food for thought.
1. You can "learn" how to run all the sophisticated audio gear in the world, but no school can give you an "ear" for sound. You can learn color theory and programming syntax, but no school will give you an "eye" for creative lighting.
These things can be learned, but not really in a class room.
2. Pick one. Audio or Lighting. Nobody really makes a successful career out of both, although I suspect there are many that will argue that, it will depend on what you consider to be successful.
3. Don't think spending ten's of thousands of dollars will mean when you graduate your going to get a job as a lighting
programmer or mixing
FOH (or monitors). Your going to have to work your way up, alongside people who opted to spend the same 2 to 4 years you spent in school working
thru the local union
hall or in a rental shop (getting paid to learn, not the other way around).
While Full Sail may have a wonderful video and graphics department, I have know too many people who have graduated and then started working as stagehands and in rental shops after spending 10's of thousands of dollars.
If you want to be a
lighting designer, go to a real college- at least you'll get to work on several real productions each year and you'll be learning the nuts and bolts as well as the production...
If you want to be a
production electrician, go to your local IA union and sign up to be on the
call list, or find a
stagehand labor company and get on their list (try the union first). Ditto for a career in audio... learn the trade from the
ground up, it will take years. I don't care how smart you are or how technically proficient you are, if you can't run a crew or can't deal with the stress of getting a show in, up and working in a short amount of time with an inexperienced crew in a
venue that wasn't designed to hold hang trusses and lighting or PA clusters, then all that knowledge won't mean squat when the show isn't ready on time... and nobody remembers the gig's you did a great job on, but everyone will remember the one that
bit the dust.
Of course their are exceptions...
