During our night dives I really haven't been able to tell much of a difference between the 18w and the 21w and even the 10w HIDs seem just as bright though the beam is not as large and doesn't penetrate as far.
However last night while swimming out to our drop the four of us pointed our lights at the building across the street. The 10w lights barely showed up and were washed out by the 18w. The 21w washed out the 18w.
Then we realized that if we didn't quit shining our lights on the building the residents would probably call the police.
