Hi,
I'm a light designer architect with a lot of experience in interior and lighting design. I have a lighting simulation job in my portfolio, where I was able to control the amount of lux distributed in the room. In addition, I performed others with the same purpose, and I know I can do this job.
I saw the .pdf and the .dwg files you posted, I can create this model in DIALux, make simulations, and add, move, or remove lamps if it is more appropriate for the lighting you want. If you enjoy my work, we can continue working on other projects. I await your reply.
