 Below is from the Nikon SB-800 manual, as can be seen reducing the flash duration reduces power.
1/1050 sec. at M1/1 (full) output 
1/1100 sec. at M1/2 output 
1/2700 sec. at M1/4 output 
1/5900 sec. at M1/8 output 
1/10900 sec. at M1/16 output 
1/17800 sec. at M1/32 output 
1/32300 sec. at M1/64 output 
1/41600 sec. at M1/128 output
