I need to buy a light kit to do some portrait photography!. Just doing it for family and close friends, not professionally, although I do want the photos to look good!. I'm looking at a JTL SL-160 basic lighting kit!. 160 w/s 120 GN!. Will these lights be strong enough on their own, or do I need a stronger light!? Thanks for everyones help, this forum has been really helpful!!!Www@QuestionHome@Com
