Well you could cover about 4'x 10' of it anyways,think of each one like a conventional 1k and your pretty close.
The
gavita foot print isnt really square,its a little more like a rectangle like the reflector.Movers are cool,ive never really ran one myself but i would guess the 9ft to be good but the 6' width might be a little optimistic but hey if it works it works!How does it yield?One thing i have learned is everyone has different ideas,give 5 people the same equipment and they will set it up 5 different ways and none are wrong,just different.
Ive run them for a few years,i had 1ks at first but got rid of them because of my 8' ceilings,live and learn.I change the bulbs once a year.
Id use 1ks if i had ceilings that tall,2 up high would crosslight a nice area and six is right,easy to suck the heat out of the peak too.
