This fans gear is maxed out at one foot at just the right angle. Its a mater of how long your lever is, how strong your fan is, and how you position the lever angle. You can get a high quality commercial shop fan for less than any light mover i have seen + you have a really nice fan and a light mover. Its kind of like buy one get one free.
Keep in mind the fun is getting there. everyone's set up is different and it will be trial and error. I started with just a chain from the shroud to the light and it just pulled the light and let it swing back, and progressed through about three more setups before being kind of satisfied.
I have a 1k on the way with another light mover idea that i am sure will be a head scratch er before ending on simplicity.
If you are like me, its just in my blood to take other peoples junk and make it good agian, its all i ever had.
