A method for illuminating an environment using an angularly varying light emitting device including determining a target illuminance based on a specification, identifying angular bins corresponding to illuminating one or more spatial zones or areas, and adjusting a first light flux output of at least one light source into angular bins based at least in part on the target illuminance. Adjusting the first light flux output may include adjusting it such that it is different from a second light flux output into a second angular bin. An imager may be used to identify an environment, activity, or estimate or measure the illuminance of the environment. Adjusting the light flux output in a bin may be based on daylight or traditional light fixtures or lamps. An angularly varying light emitting device or system may adjust the light flux output in an angular bin based on a target illuminance.
