LRV for baffles

Hi Carina, This is definitely a tricky question. I don't have a simple answer for you. I would simplify the ceiling to just be the projected area of the ceiling (in other words, the ceiling area without the structure and baffles), and reduce the LRV by a factor to compensate for the light losses caused by the baffles, etc.  As a lighting designer, to figure out that factor, I would lean on lighting calculation software like AGI to help figure this out, but I don't know if that is an option for you.  To do so, you would do a lighting calculation with the baffles and structure and make note of the light levels.  You could then run the same model with a false/flat ceiling, and then iteratively adjust the ceiling LRV in the model until the light levels reach the same levels as with the original model. The ceiling LRV of that matching calculation would give you a value for what the resultant LRV is given all of the losses in the ceiling geometry. I don't have a great solution other than that.
