About Energy ratings:

Energy is measured in Joules. 1 Joule = 1 Watt-second. Energy listings are the maximum per-flash energy rating (input to flash tube) for each available model. In the United States, the Watt-second is the customary unit, but this is more awkward than the Joule which is an internationally recognized unit of energy.

Some manufacturers name their models based on "effective" Watt-seconds instead of actual energy input to the flash tube. This takes into account the beam concentrating properties of the permanently attached or removable standard reflector.

Energy delivered to the flash tube provides a relative, not absolute indictation of light intensity versus another flash unit. This is because light intensity depends on many factors including flash lamp design, the application of UV attenuating coatings, diffusers, reflectors, interference from modelling lamps, etc.
