    Lux levels for fluorescent light fitting in test mode

    As the title says. I'm looking for some data so that I can calculate lux levels from a 58w fluorescent batten fitting in test mode (working off of battery). I have looked on Thorn's website but all I can find is data for normal operation (not in test). Any help would be much appreciated.
