Or you could make a more generic function:
*def setIntensity(intensityValue, lightList = None):
if lightList == None: lightList = cmds.ls(sl=1)
for light in lightList: cmds.setAttr(light+".intensity", intensityValue)
*
Then for general use:
1. Select lights and run:
*setIntensity(0.5)
*
2. **Run:
lightList = ['back_building_light_1', 'back_building_light_2', '
back_building_light_3']*
setIntensity(0.5, lightList)*
