If you don't yet have the gigs how can you know if lighting is even desirable?
Most of the weddings I do have no lighting at all. It's just not part of what they desire. My biggest lighting events in the DJ realm were Bar Mitzvahs, not weddings.
Most of my lighting today has functional requirements in addition to decor, meaning chandeliers and general illumination for tents and other non-conventional event spaces that have no lighting, or gymnasiums or other large spaces that need something different than the space typically uses. I typically don't buy lighting gear anymore, I rent exactly what I need when I need it rather than trying to repeat the same narrow answer to every lighting challenge. Instead, my inventory purchases focus is on the rigging, cabling, and control needed to make it all functional. I own the backbone rather than the actual fixtures, which allows me to rent a much higher grade of equipment and be more versatile than repeating the same thing over and over.
