I prefer to just add them in Artlantis, but all lights can be exported - which will then put them at the desired coordinates for fine-tuning in Artlantis if you need interior lights at particular locations. Only one camera (the current one) is exported to Artlantis, but you can set up as many as you want once in Artlantis - and retain these (as well as materials, lights, etc) with future model updates by using the 'reference file' feature of Artlantis.
Cheers,
Karl
