CMA dude the Ms006 have two switches on them.  Which allows you to adjust the power output of the lights.  Bascially if you have both switches on all of the 6 lights are on.  If you switch one switch off them 4 lights are on and 2 are off.  If you switch the other switch off and switch the other switch back on, 2 lights are on and 4 are off.  If you switch both switches off all 6 lights are off.
EDIT: Hence essentially you can have 2 x ms006 and run them light 2 x ms004 if you just leave two of the lamps off and four on. But seriously.. can you ever have too much light?
Yes I know the answer is yes you can have too much, but it's good to have the option to crank it up!
