    This paper compares the different visual objectives that have been used in side-by-side matching experiments. In tests, two different fluorescent lamps were compared in juxtaposed booths by a series of observers. It was found that:(i) there was no significant difference in illuminance ratio when matching the booths according to six different visual objectives including equal brightness, equal clarity and equal pleasantness; and (ii) the matched condition was not predicted by illuminance based on V(l). The data exhibited the error associated with the application of dimming previously noted by Fotios.
