Hi all,

Haven't seen much evidence that "nit" light levels (luminance across surface) are readily documented, particularly since signs are often customized fabrications. Has anyone identified a reasonable method for project teams to calculate performance if internal light fixture is known.....not sure if one can extrapolate nit light levels using initial lumens? I'd expect the color and opacity of the sign surface to be a major factor as well.....light emitted from a thin gauge white plastic sign face would be brighter than a thick gauge dark blue plastic, for example.

Welcome any tips to overcoming this obstacle, particularly when eliminating internally lit signage is not an option and all other credit requirements can be met by the Project design!
