Your paid a lump sum gig to gig. Salaried lighting designers do not exist, at least not that often in the
theatre world. Your paid a sum that does not have taxes, social security, medicare, or whatever other charges are taken out of your paycheck. Added to that, your not getting any benefits or retirement. You might bring in 50k a year if you are good, but that gets eaten up quick come tax time. Added to that, you have the overhead of buying a computer, paying an accountant, keeping software up to date, incidental travel expenses, paying an assistant if needed, keeping an apartment that you will never see, or whatever else you can think of.
Most gigs can pay from 100 to 5,000 per show. Usually it takes about a 2 weeks worth of time to put up a show. That time can be spread over months, but your going to be spending at least 14 days working on the show from pre-production to opening. That can change depending on the
theatre and the caliber of the show. Broadway LD's still do 10-15 shows per year.
To "make it" as an LD, most people want to be doing at least 2 shows a month, if not 3. In order to pull that off you not only need to be working at multiple theatres but also be working in multiple cities.
Its a hard
road to get started at. If you can get your USA829 card it get a
bit easier and the money gets better. Still though, its a hard
road to go up. Working as an assistant in between gigs for other designers is the way to get started.
So, as far as a salary goes... there is no way to predertermine it. Of all of my freinds that are soley designers in NYC, none of them are only doing that. One has a temp job in an office, another does the waiter thing.
Because LD's can work so many shows a year, they are less in demand then scenic and costume designers. A costume designer or
scenic designer has a good year if they do 5 or 6 shows. They are paid much more but they are usually on site for much longer.
If you want to do the M.E and LD thing all rolled into one that opens a few doors for you at smaller companies. That can also close doors for you later on. It has been said that when you move to NYC you have two choice, your either a designer or a technician and once you pick one don't look back. You can argue that one however you want, but I am just throwing it out there.
