An Aether II only uses one Lense per light unlike the Original which took 6 lenses per light.They are the: FL model - Flood light which is 35 degNF model - Narrow Flood which is 24 deg SP model - Spot which is 15 degYou also can use no lens for the widest flood which will light a large area up.RJ
This may help with angle of lenses, to gauge on the rough throw of light.
